Plate Tectonics

1. A zone where one plate moves under another plate.
4. Places of permanent convection. Volcanoes move in chains.
11. A type of fault when the break in the crust is due to compression built up at a convergent boundary.
12. A piece of lithosphere that slides slowly over the asthenosphere.
13. The tectonic plate that is more dense and thinner.
14. A deep valley in the ocean caused by convergent boundary plate movement.

1. A type of fault when the break in the crust is due to shearing built up at a transform boundary.
2. A boundary where two plates come (move) together.
3. What happens when plates move by sliding past each other and the rock slabs rub against each other.
5. A super continent made of all the current continents together 225 million years ago.
6. A boundary where two plates move along side each other.
7. A type of fault when the break in the crust is due to tension built up at a divergent boundary.
8. A boundary where two plates move away from each other.
9. A landform with magma inside that erupts and is pushed out of an opening and magma becomes lava.
10. The tectonic plate that is less dense and thicker.
