Plate Tectonics

4. These occur at transform boundary faults and can cause tremendous devastation
5. Layer of Earth with the lowest temperature
6. When one tectonic plate moves underneath another one, it’s called this
7. Type of plate boundary where two plates collide
9. Earth’s thickest layer
11. Theory that the lithosphere is divided into tectonic plates that move on the asthenosphere
12. The bending and crumpling of rock. This happens at continental vs. continental convergent boundaries and results in the tallest mountains
14. This is the process of creating new oceanic crust
15. Theory that the continents were once joined as one large, single land mass
17. Word used to describe the state of the mantle
18. Type of plate boundary where two plates separate or move apart

1. Scientist that proposed Earth’s continents were once joined together in a single land mass
2. The process of plates sliding past each other in opposite directions. This can be found at transform boundaries and results in faults.
3. Layer of Earth that is composed of Fe & Ni and is solid
5. Type of crust that is thick and contains granite
7. This is a type of heat transfer (hint: lava lamp). Some scientists believe these are occurring in the mantle and moving the tectonic plates
8. Areas along a transform boundary created by the shearing of two pieces of crust. There is a famous one in California
10. This forms on land at divergent plate boundaries. There is a great one in eastern Africa
13. These form under water (on the ocean floor) at most convergent boundaries
16. Layer of Earth that is composed of Fe & Ni and is liquid
