Shaping Earth’s Surface

2. Mountains formed by the folding of Earth's crust due to compressional forces.
4. The force that squeezes rocks together, often causing folding.
6. A plate boundary where two plates slide past each other horizontally.
8. The effect of things acting upon one another.
10. To move something out of its position.
14. A large sea wave caused by an underwater earthquake or other disturbance.
17. A sudden release of energy in Earth's crust, causing ground shaking.
18. The height above sea level.
19. An area with many fractures in Earth's crust associated with a fault.
20. The edge where two tectonic plates meet.
23. A curved chain of volcanoes formed above a subducting plate.
24. Forming a 90-degree angle.
27. Large pieces of Earth's crust that move over the mantle, causing geological events.
30. A deep gorge carved by river erosion.
31. The breaking down of rocks by natural forces like water or wind.
32. To come together with force or impact.

1. Involving sudden and great damage.
3. The process of a denser plate sinking below a less-dense plate at a convergent boundary.
5. A circular depression formed by the impact of a meteoroid.
7. Movement of one tectonic plate in relation to another.
9. To cause something to happen.
11. Molten rock that has erupted onto Earth's surface.
12. The movement of weathered materials by wind, water, or ice.
13. A plate boundary where two plates move toward each other.
15. Stress that pulls rocks apart, leading to faults or rifting.
16. A deep valley formed where tectonic plates move apart, typically at divergent boundaries.
19. Mountains formed when blocks of Earth's crust move up or down along a fault.
21. A plate boundary where two plates move apart.
22. A break in Earth's crust along which movement occurs.
25. The rapid downhill movement of soil and rock caused by gravity.
26. A vent in Earth's crust where molten rock, gases, and ash are expelled.
28. Molten rock beneath Earth's surface.
29. The force acting on rocks to deform them.
