Earths Core : Armanielle

2.  The mantle is the thickest layer. It is 5 km thick.

3.  Together the crust and the very top of the mantle make up a layer called the

Lethal Sphere.

4. Under the layer called the Lethal Sphere is another layer in the mantle called the
asthenosphere.  

Share one fact you learned about the asthenosphere here: Metal Rocks

5.  The temperature at the top of the mantle (up by the crust)
is much cooler than the temperature at the bottom of the mantle (by the outer core).

What is the temperature at the top of the mantle? 4,000 °C(7,230 °F)  

6. What is the temperature near the bottom of the mantle? 7,000 degrees

7.  Is the outer core a solid or a liquid?    Liquid

8. What is the outer core mostly made of? Rocks and Mantle     

9. Is the inner core hotter than the sun?     It’s as hot as the sun.

10. How hot is the inner core, (10,800 F)

11. Why isn’t the inner core a liquid, when it is SO hot?! Why hasn’t it melted

Because its made from rocks and irons

12. Put the layers of the Earth in order from coolest to hottest!

Coolest:     Crust

Next-coolest: Mantle

Getting hotter: Outer core

Hottest: Inner core

13.  The outside layer of the earth is made up of two different types of crust called the
continental  crust and the outer crust. We live on the continent crust and the outer crust is
found under the oceans!

Explain, in your own words, what convection currents are and why they are important.
Write your answer here: They are important because One of the most important roles
of ocean currents is in governing Earth's weather and climate. Western boundary
currents such as the Gulf Stream carry large amounts of heat from tropical waters
to the north.
