Layers of the Earth

4. A liquid layer that generates the Earth’s magnetic field due to its motion.
8. A dark rock that primarily makes up the oceanic crust.
9. A semi-fluid layer below the lithosphere where tectonic plates move.
10. A layer beneath the crust, composed of semi-solid rock that flows slowly.
12. A rigid layer consisting of the crust and upper part of the mantle.
13. A solid sphere at the Earth's center, composed mainly of iron and nickel.
14. The Earth's outermost layer, consisting of solid rock.
15. A protective field generated by the outer core, shielding Earth from solar wind and cosmic rays.
16. The innermost layer, consisting mainly of iron and nickel and divided into the inner and outer core.

1. Waves of energy that travel through the Earth’s layers, used in studying the internal structure.
2. The dominant rock found in the Earth’s mantle.
3. Large pieces of the Earth’s lithosphere that move due to mantle convection.
5. A force that increases with depth within the Earth, affecting material states.
6. The movement of material within the mantle, driving tectonic plate movement.
7. A common rock found in the continental crust, lighter in color and density.
10. A boundary separating the crust from the mantle, also known as the Moho.
11. A process occurring in the outer core, generating the Earth’s magnetic field.
