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.
