Layers of the Earth: Flashcards
The structural layer that is the source of Earth’s magnetic field. Outer Core
2. The layer of Earth that “flows”. Asthenosphere
3. The structural layer found below the asthenosphere. Mesosphere
4. The structural layer that is made up of solid mantle rock. Mesosphere
The structural layer that is made of melted iron and nickel. Outer Core
6. The thicker type of crust. Continental
7. This layer makes up 2/3 of Earth’s mass. Mantle
8. The compositional layer found on the surface of the earth. Crust
9. The layer that has convection currents that moves the plates. Asthenosphere
10. The thinner type of crust. Oceanic
11. The older type of crust. Continental
12. Structural layer made up of the crust and the upper part of the mantle. Lithosphere
13. The less dense type of crust. Continental
14. The layer that contains magma. Asthenosphere/ mantle
15. The layer that makes up Earth’s tectonic plates. Lithosphere
16. Structural layer that is a solid metal ball in the center of the Earth. Inner Core
17. The youngest type of crust. Oceanic
18. The compositional layer made up of iron and nickel. Core
19. The compositional layer that is under the crust. Mantle
20. The three compositional layers. Crust, Mantle, Core
21. The five structural layers. Lithosphere, asthenosphere, mesosphere, outer core, inner core
22. Layers divided by what they are made of. Compositional
23. Layers divided by how they work. Structural
24. The top structural layer. Lithosphere
25. The middle compositional layer. Mantle
26. The innermost compositional layer. Core
27. The innermost structural layer. Inner Core
28. The “middle” layer. Mesosphere
29. The thinnest compositional layer. Crust
