Explanation:

1. A fault is a fracture or zone of fractures in Earth's crust where movement occurs.
2. A convergent boundary is where two plates move toward each other.
3. Subduction is when one tectonic plate sinks beneath another into the mantle.
4. The asthenosphere is semi - fluid and allows tectonic plates to move.
5. A divergent boundary is where two tectonic plates move away from each other.
6. Plate Tectonics is the theory that explains Earth's lithosphere being divided into moving plates.
7. A tectonic plate is a large, rigid piece of Earth's lithosphere that moves independently.
8. A transform boundary is where two tectonic plates slide past one another horizontally.
9. The mantle lies between the crust and the core.
10. A fold is a bend in rock layers caused by pressure and stress.
11. An earthquake is a sudden shaking of the ground due to movement along a fault.
12. The core is the central part of Earth made mostly of iron and nickel.
13. A volcano forms when molten rock, gases, and ash erupt through Earth's crust.
14. The Mid - Ocean Ridge is an underwater mountain range that forms at divergent boundaries.
