Earth's Crust

This blog post is a reflection of what I this week in science class about earth's structure and caves. We watched 2 Bill Nye videos called Earth's crust and caves.
The layers of the world!!
1 thing that I learned was the layers of the earth. Which are: Crust(we live on that layer), Mantle(that's the second layer), the Outer Core(getting hotter), and finally the Inner Core(the hottest!!!). The inner core is basically solid. The outer core is made out of liquid. The mantle is made of plastic. And the the thing that we stand on rite now, the thing that is the smallest but it gives us the most protection,, is made out of rock.



In this picture that i found shows the different temperatures and the length of layer. It also shows what the layers are called and what the layers are made of.








The Animals that live in the caves!!
There are three types of groups of animals that live in caves. The 1st group is called Trogloxenes. They are cave visitors. For an example a bear an owl and a bat are Trogloxenes.
The 2nd group is called Troglyphiles. They love the caves! 1 of the animals that loves the caves the most is a worm. The reason why they love it so much is because i is very moist and wet down in the caves and that means that if it is wet and moist then the ground gets wet and the worm love mud, so that's why they love being down in the caves!


And the 3rd group is called Troglodylos. They are cave dwellers. Some of the animals that live there are fish, lizards, spiders, and crayfish. Crayfish
