I really like the Dynamic Earth because it tells everything you need to know about earth. My favorite part was that the pictures were really beautiful. I also really liked the video of how earth and solar system was formed.
The earth is made up of different layers. The layers are the inner core, outer core, inner mantle, outer mantel, and the crust. The core is made out of iron-nickel, which is 1500 °C. It is hotter than the sun. The inner core is a solid metal because of the pressure. The outer core is molten and it 1350° C, and the movement is what makes the earth’s magnetic field. The mantel is made of liquid silicate and is 1200°C. There is an upper and lower mantel, which make up the liquid that moves the plates in the crust. The Crust is where people live and the temperature varies depending where you live.
METEORITES:
Meteorites are big rocks that crash into earth. They come from asteroids. Meteorites and earth are very similar because they were born at the same time as the earth and sun. Meteorites tell us what kinds of materials are inside the earth because we can’t drill inside earth. Another thing we can study is peridotites, which are rocks that come from the upper mantle. Peridotites come to the surface by hitching a ride on the magma.
