Plate Tectonics

3. The largest layer of Earth's interior, making up approximately 84% of Earth's volume.
4. Sometimes when an animal dies and its body decays, it can leave an imprint in the sediment. If this imprint fills in with minerals from sediment and groundwater, it can harden to form a fossil. This fossil is called a _____ fossil.
6. A plate boundary where two plates are colliding.
7. An opening in the Earth's crust through which lava, ash, and gases erupt.
10. A plate boundary where two plates are separating.
11. An intense shaking of Earth's surface.
14. A plate boundary where two plates are sliding past each other.
15. The type the rock that is formed from lava or magma cooling.
17. A large wave caused by movements in Earth's outer layer, or crust, which move ocean water.
18. The type the rock that is formed through heat and pressure with going through a liquid state.

1. A zone in the upper mantle of the earth, consisting of hot, plastic rock, that underlies the solid lithosphere.
2. A natural upward projection of the earth's surface, higher and steeper than a hill and often having a rocky summit.
5. The type the rock that is composed of different sediments.
6. The very hot, very dense center of our planet
8. The outermost shell of a terrestrial planet.
9. Any remains, impression, or trace of a living thing of a former geologic age.
12. An area of the Earth's mantle from which hot plumes rise upward, forming volcanoes on the overlying crust.
13. The imprint left by the shell on the rock that surrounded it.
16. The rocky outer part of Earth. It is made up of the brittle crust and the top part of the upper mantle.
19. Geological records of the activities and behaviors of past life.
