The Day The Mesozoic Dieded

The video that i watched was about how scientists didn't know what killed the dinos or when they were killed. So they researched and they explored all around the world about this and discovered that none of the dinosaur fossils were above the KT boundary. That gave them the idea that they should compare the fossils above and below the boundary. They also discovered that the meteor that caused it all was under the Yucatan Peninsula. They even figured out that the meteor hit the edge of one of the continents and the seafloor was pushed into little rocks.

The Day The Mesozoic Died

The video talk about the Mesozoic Era and how the dinosaurs died. The theory came when a scientist proposed that a astroid from space came to earth and kill all the dinosaurs. There is a boundary  called the K-T Boundary, witch separates the Mesozoic Era with Cenozoic Era. The astroid hit in Chicxulub, Mexico. Dinosaurs that were close to the astroid were broiled alive and killed instantly. Dinosaurs that were further away death came later for them.

The Day the Mesozoic Died

For a very long time they couldn't figure out why there was thin clay layer around the earth's crust. Many had seen this layer and they started to gather information and missing pieces to this problem. They thought that since in places there were different types of rocks mixed together that there had to be a bigger cause then just natural processes. They had realized they were coming closer to the spot were they thought was a meteor. They finally used new tech to get a narrow area to search. They had finally found the spot where it landed. They have later discovered that there isn't any of the same species below KT boundary and above KT boundary. There had been many discoveries since then.

The Day the Mesozoic Era Died

In the video they talked about how the Mesozoic Era came to an end, how they figured out how, and how life was post- asteroid. Geologists and paleontologists had spend years trying to figure out what the KT boundary was telling, and after looking at it all around the world, they came to the conclusion that an asteroid had hit the earth, that was the size of Mt. Everest. After the asteroid hit, the earth heated up and killed off all the dinosaurs and 60% of the plant life. Evidence of life below and above the KT boundary is extremely different, there hasn't been a dinosaur fossil found above the boundary anywhere in the earth. After the strike, life such as mammals and small reptiles that had big populations, somewhat survived. Then, the age of mammals began.

The Day the Mesozoic Died

A massive crater came down and nailed the surface of Earth in Southern Mexico. It caused an insane amount of impact that sent debris in every direction, as well as massive tsunamis that sent 100 M high waves that covered half the land. The amount of ash that was sent into the atmosphere completely blocked off the sun and prevented any organism that relied on photosynthesis to flourish. And for organisms that didn't rely on photosynthesis, they were practically boiled under the heat of the crater. Discovering the crater was a different process though.  It took lots of research and searching, but once scientists discovered the KT boundary things began to piece together. They discovered that the KT boundary contained a rare element that was only found in astroids, so obviously an astroid had to have been there. They also examined that the texture of the layers above the KT boundary was different than the texture of the layers beneath the KT boundary. Scientists found that dinosaurs were only found beneath the KT boundary and above the KT boundary scientists were completely whipped out. They went and did more research down in Texas and discovered that mud from the bottom of the ocean was on land so it must've been underwater at one point in time. They continued to follow the information they gathered and they finally discovered a massive crater in the Ukantan Peninsula in Mexico that contained the same elements that was found in the debris that was found all over earth and in the KT boundary. Another thing that pieced it together was that half of the crater was in the water and half of it was on land so it would have sent waves all over Earth causing large tsunami's and dragging ocean mud onto present surfaces that ocean mud wouldn't be expected to be found.

The Day the Mesozoic Died

Once ago scientists believed that mesozoic era ended by very slow change overtime. But then a man thought otherwise. He thought they they all died in an instant by a giant meteor. Scientists wouldn't believe this catastrophic event. So he went out to prove them wrong. He eventually found a giant crater in Mexico. There him and his scientists found fossils of land and sea animals. You could just find them lying around all around the ground. He also found that rocks that could only be that way unless a catastrophic event happened. He proved those scientists wrong and today we believed that a meteor killed all the dinosaurs.

The Day The Mesozoic Died

The day the Mesozoic died, millions of years ago. There is a lot of proof of when they died, a lot of it has to do with the layers of the earth. All of the fossils are different and have different animals and fossils in them. When the meteor hit the Earth, it caused major amounts of heat to be put on all of the animals near it. All of the debris in the air blocked out the sun to the plants and animals. Once some of the animals started dying, it killed off others. And without the sun plants couldn't produce photosynthesis and they all died off.

The day the mesozoic died

I would say that this video helped me a lot. The k-t boundary was really the turning point towards dinosaurs. When that meteor hit, it was the end no matter what. The tsunami though was really interesting. I didn't know that that was a way for the the rocks to move all over the world. The part about how Wyoming had that big tsunami hit it and make all the rocks split up the fossils was confusing because I thought that all the dinosaurs died fast due to the meteor exploding and shooting lots of things in the air. The leafs remains in the rocks  was extradorniary because I never knew even the color would stay the same even through that many years.

The day the Mesozoic died -- Hannah

The day the mesozoic died in when all the dinosaurs died. A huge astroid hit earth at a very fast speed and collided with earth and made a huge explosion. The ash and smoke stayed in the air for a very long time and photosynthesis  died out and killed all the producers and then soon all the consumers died because they couldn't eat. You can find fossils all over the world form the dinosaurs and when you look at the mountains on earth you can tell by certain signs that somethings happened in earths history bc it looks different then before.

The Day the Mesozoic Died

In the video I watch, they talked about many things. One thing they talked about was that if an asteroid that was 10 kilometers deep landed on a sea or an island, it would displace incredible amounts of rock and water, that can cause tsunamis. The scientists took rock examples to use in the lab that showed all the signs of a high energy impact. This made everyone believe that there was a big crater buried on the peninsula. Later they named the crater the Chicxulub crater. 

When you crack open rocks you can see the leaves on plants and can tell what insects ate them. Fossils fill the whole place, which describes uniformitarianism which says that things in the past also happen today, which fossils do. Scientists found a boundary they named the KT boundary, which can tell the age of fossils. This boundary helped determine where many things lived because they can tell where in comparison they were from the boundary.

Smoke from fires later filled the air, as long as sulfur that exploded in the air, the Mesozoic era, the life of dinosaurs was over.  This wrecked over 60 percent of plant life. The asteroids were very bad within life back then. Many disasters occurred and many things died down.

The Day the Mesozoic Died (Kelsey Osborne P4)

           The Mesozoic Era was a time of many different creatures, especially dinosaurs, but they weren't there the whole time. Much of the land was underwater, which is marked off by a layer called the K-T boundary. When a meteor around ten kilometers wide hit the Earth, though, it displaced a lot of the water and land. All of the displacement as well as the debris coming off of the meteor buried most of the animals, not leaving much. A few of the smaller animals luckily survived the day the Mesozoic died, which left a promising future millions of years later for us.

The day the mesozoic died

In the video it started out with a discovery of the tk boundary. They explained how this told us about the eras and periods before us. They also showed us how to find a boundary and a difference between a boundary. They also showed us a discovery of a boundary.

After they taught us about the tk boundary. They then showed us how the mesozoic died and how they went extinct. They were all killed by an astroid that was aiming towards the earth. It landed by Mexico which killed all of the dinosaurs. That is how they were all killed.

The Day the Mesozoic Died

The Chiczulb crater has finally been found next to a town next to the gulf of Mexico. Researchers went out and looked to see which animals went extinct and ofter questions. Curt found the KT boundary in north dakota, and when he found that he could answer many more questions.  They are finding carbo films. fossils. and what insects eat what things. They are finding fossils almost anywhere, big, small, long, short. They have found out that 22 type of of dinosaurs lived in hell creek.

At the beginning of the video they were trying to find the cater that killed off the dinosaurs. it was 100 kilometer wide, and the sky was covered in smoke and the sky was not visible. Dinosaurs next to the crater died because of ashes and sparks just boring them to death. Dinosaurs farther away for the crater died a slower death because as fires started spreading around smoke filled the air and the animals breathed in the smoke and they died.

Geologist have found the crater of the asteroid that killed off the dinosaurs. It was around 100 kilometers wide. The explosion was so big the sky was covered in smoke and the sun was not visible. It killed off all of the dinosaurs in a time span of a couple hours.

Geologist have also found a boundary in the rocks called the KT Boundary. They can tall judge the age of fossils and rocks by how far they are from the KT Boundary.

The Day The Mesozoic died

I watched a video about the dinosaurs and how they died. There was a meteorite the size of Mt Everest and it was hurdling towards Earth 20x faster than a bullet. If the meteor were to land in water then it would have made 100m tall tsunami and it would keep going until 1 month passed. They told us how the dinosaurs died and that is how.

The Day The Mesozoic Died Video Recollection

In science class over the period of about two days, we've been watching a 34-minute video about the day the Mesozoic died. It talked about these scientists who investigate this asteroids crater. When it hit it displaced a lot of laters of ground material and left a big "dent" in the earth. When it hit a lot of dinosaurs were "broiled" alive within an hour of impact. This caused big fires. These fires launched dangerous substances into the air and completely whipped out the dinosaurs ability to breathe as well as obliterated the sun! Without the sun the plants couldn't complete their photosynthesis processes and everything dependent of that was lost. 

That was a really informative video. The scientist discovered that the astroid hit and measured it and it was ten times the sizes of a atomic bomb. When the bomb hit it created a small layer of clay that divided the Mesozoic ear that the dinosaurs lived on and the cenozoic

The day the mesozoic

what happened was that there was a thin layer of unknown clay they stated to dig and they started to find fossils and then they wondered what happened and so a comet or astorid came to earth making it the animals died painfully.and people started asking what happened to the animals and why did some died and how come other animals lived? that is a mystery that no one else knowns.

The Day The Mesozoic Died

         It was about how life on earth was slowly broken over time.  The dinosaurs became exitinct over the millions of years. In the years more species came to life and roamed the earth for lots of years and the population of species started to slowly go down. Between the volcanoes erupting and the ground weathering away the envoiroment for the species became very bad and many animals lives were lost. Only certain animals still live to this day but  most of them have died and not longer are in the earth only the fossils of the animals that once roamed the earth.

The Day The Mesozoic Died

           It explains a lot in which the dinosaurs died, because of a giant meteor shower, and they got burnt into a crispy potato chip. Now lets say if they were baked with the heat of a meteor shower, than how would that impact the dinosaurs in the water very far away from where the meteors struck. Also if there was a giant water and sediment movement then wouldn't it affect where the dead dinosaur bones were laid? I understood that there was a giant meteor and it crashed into the earth making a giant tsunami, and later a death of all the dinosaurs.

THE DAY THE MESOZOIC DIED

The video talks about how a Tsunami came and it moved everything around and made it look a lot different then what we know it as today. Rocks looked different after the Tsunami. The ground was torn up and rocky. There were many animals that died during this era.
Millions of years ago the whole world was underwater. Everything you look at right now was at some point in time underwater. If you would every go to yellowstone of somewhere with some big mountains. You will notice that there are outlines in the rocks that is proof that at some point in time it was underwater. After the Tsunami happened It all turned into the mountains you see today.

The day that Mesozoic died

The video that we watched was very informational because it told us the day that Mesozoic died. I really liked that how in depth the video went. I never really understood things like that before but i felt that i could understand it a whole lot better than before. The giant astroid that crashed and demolished the dinosaurs and they could not find where the astroid hit they had no evidence  even if it hit but then they found it in the Yucatan peninsula.

The Day The Mesozoic Died

This video talked about how the asteroid came out space and hit the Yucatan peninsula. The asteroid came down and hit the peninsula and created a bunch of huge tsunamis that took the rock and displaced it all over the ocean. Then the gasses and stuff from when the asteroid hit, filled the sky and all of the producers began to die because they couldn't do photosynthesis. Then the small animals began to die, which led to the larger meat eater began to die because they had no food 😱😭😭. Then after a while the sky began to clear and photosynthesis began again and life started back up with the small animals after about 1 million years. Larger animals began to roam and again. 😃🤗🤗

THE DAY THE MESOZOIC DIED

The day came to earth when a great asteroid fell to earth and killed all the dinosaurs but only small animals survived.   some of the animals that could survive were the animals that lived in the water and those who lived below the earth. The asteroid was the size Mt. Everest and the force of 100 atomic bombs.

The Day the Mesozoic Died

The video was about a belief that an asteroid struck the Earth and killed the dinosaurs. After that, a new era began. Researchers examined fossils and came up with this theory.

Video

The video told about how the Mesozoic era ended. How many things they had to find to solve it. then found out what hit the earth that ended life.

The Day the Mesozoic Died

The hypothesis of the way the Mesozoic died is that a large astroid or commit that was as big as Mount Everest hit Earth. IT mad a big crater by the gulf of Mexico. Most people didn't think that the astroid hit the Earth or that this hypothesis was true but after many years of research they proved with evidence like shocked quarts and shocked minerals that it really happened.

The Day the Mesozoic Died

People thought the dinosaurs died off slowly, but other people discovered that it really didn't happen that way. They found a clay layer that showed that none of the earlier fossils were still there. The clay layer was really weird, and they set out to find out why there was clay there and what it meant. Later down the road they discovered that an astroid had hit the Earth, but they couldn't find the crater. Around the Gulf of Mexico they found the crater, and all the puzzle pieces went together to explain the day the Mesozoic died.

The Day the Mesozoic Died

The video says that an asteroid was the cause of the death of all dinosaurs because when it hit the ground it sent impact over the land. The impact was so large that it killed everything that was living at the time. The ash from fires and everything else covered the sun which caused the things that thrived on the light to die off because they didn't have the light anymore. They discovered this by finding evidence of things that could only be there if a huge impact had been caused like many different kinds of rock that came from different areas on Earth were all found in the same area. Also, as they look at the KT Boundary they find lots of dinosaurs and reptiles before it, but there is no sign of any of them after it. Which helped them come to their hypothesize that an asteroid hit the Earth and killed them all off.

The Day the Mesozoic Died

The day the mesozoic died explains how the scientists discovered new ways to find the remains of animals. It also tells us what the cause was for all the death of the mesozoic animals. Then they told us what the of animals survived the terrible disaster. Finally it explained how you can tell if your area you live is a place where the mesozoic used to roam the land.

The day the Mesozoic died

The day the mesozoic dies mostly tells the story of how scientists examined many lines of evidence to retell and even that occurred 186 million years ago. Rocks that were formed during the "age of dinosaurs", or as we call it, The mesozoic Era, are found in the Connecticut river valley in portions of the States of Connecticut Massachusetts. Rocks of the Mesozoic Era have been dates as having to be formed during the period from about 65 to 248 million years ago. The mesozoic is about dinosaurs and when they existed on earth. The mesozoic tells us when is occurred. That was, as i said, about 186 million years ago. The mesozoic is split into three periods. The Triassic, Jurassic, and Cretaceous Periods. 

The Day the Mesozoic Died

What the video was explaining how scientists hypothesized how the Mesozoic era died. There hypothesis was that an astroid landed on earth and with the energy from that killed off all the reptiles and dinosaurs. As they look at the KT boundary they find lots of dinosaurs before it they found dinosaur fossils and remains, but after that they don't find anymore. Scientists are still trying to solve some of these mysteries, but they think they figured this one out.

The day the mesozoic died

There was dinosaurs in the beginning of the video and they where just living normal until an commit hit the earth that was huge and weighed hundreds of millions of tons and it landed in Mexico and the scientist found that because of some layer in the rock. Then after they studied they where able to tell what animals lived in what period, and what part of the earth.

The day the Mesozoic died

What this video was about is it was explaining how the Mesozoic era age of dinosaurs died and how we can tell that by aging rock and by minerals. How this happened you may ask? Well lemme tell you. What happened is millions of years ago dinosaurs thrived on this planet we know now as "earth" but one day an asteroid about the size of mount everest hit the earth creating the biggest explosion ever. What happened after this is the debris that exploded into the air orbited the earth for a while before it fell down and with that in the air and all the smoke in the air, there wasn't no sunlight. Because of this no photosynthesis no photosynthesis means no plants no plants mean no food for herbivores no herbivores mean no food for carnivores and that means the extinction of dinosaurs.

The Day The Mesozoic Died

It talked about how the dinosaurs died and how living things came back after the extinction. There was an astroid that hit the earth and they all died, but some smaller animals survived. They used rocks as evidence to show exactly how the astroid destroyed everything. Not a lot of people believed the guy, so he had to do more researching and eventually, they found exactly where the astroid is. There are boundaries and all of them so far have been found under a certain one. That shows that almost no living thing survived the astroid.

What’s the Matter

What’s the matter, oh it is that some people don’t know what things are. Most people now say that things are made of matter. They need to know that there is more to it. Sure everything is made of matter but can be classified as one of the 3 types of matter solids, liquids, and gases.

            First, one of the most common types of matter to find around are solids. The thing that you can easily classify them from the other types are their definite shape and definite volume. That means that they keep their same shape and have the same space all the time. Another way to spot them out is that their particles are in fixed positions. That means that the particles that make up the solid stay in the same spot all the time. Some examples of solids are computers, cars, and water bottles.

            Next, the second type of matter is a liquid. They have an indefinite shape and a definite volume. That means that their shape and and the space they take up is the same it takes up the shape of its container. Another way to think about them is that their particles attract. That means that it will fit to the shape of their container. Some common examples of liquids are water, soda, and milk.

Types of Volcanoes

Types of Volcanoes

            People have seen or heard about volcanoes, but do they know what kind they are? Volcanoes are one of the most destructive forces on Earth, and there is more to them than what people think. Today, we know about more about them than we did before. Since they are so destructive, people should know how to tell them apart, like the cinder cone, the composite, and the shield volcano.

            The most common type of volcano is the cinder cone. Cinder cone volcanoes are single vented, and because of that, they erupt straight up building the base higher with gas, ash, and lava. Cinder cones are usually not that violent, but they can do damage. There is usually not a lot of lava that comes out of it except for building the volcano higher. Mount St. Helens is a famous cinder cone volcano.  One other kind of volcano is a Composite volcano.

           

            Composite or stratovolcanoes, are steep sided with one main vent and smaller tubes reaching to the outside of the volcano. Composite volcanos can make up some of Earth’s highest mountains. They can be up to 10,000 feet tall. When a composite volcano erupts, it goes at very high speeds, shooting out hot magma and gas out the main or one of the tubes to the side. One famous composite volcano is Mt. Fuji in Japan. The last volcano is a shield volcano.

            Shield volcanoes are low to the ground with lots of vents layers with lava. When they erupt, it is low explosive, and the lava runs or splatters. The lava is very fluid so it can do a lot of damage to buildings and other things. Shield volcanoes are especially dangerous for towns that live right by a volcano because the lava runs a splatters fast. Mauna Loa is famous shield volcano. These are some of the volcanoes that people would see on a trip.

            When someone sees a volcano, they will now know what kind, what they look like, and how much damage they can do. There is cinder cone, composite (stratovolcano), and shield volcano.
