3. A large natural elevation of the Earth's surface rising abruptly from the surrounding area.
6. The thin, outermost layer of the Earth where we live.
7. A fracture in Earth's crust where blocks of rock have slipped past each other.
9. Molten rock located beneath the Earth's surface.
11. The layer of gases surrounding Earth, held in place by gravity.
12. Natural features of the Earth's surface, such as mountains, valleys, and plains.
13. The central part of the Earth below the mantle, consisting of a liquid outer core and solid inner core.
14. The breaking down of rocks and minerals on Earth's surface through exposure to the atmosphere.
17. The rigid outer layer of the Earth, comprising the crust and upper mantle.
18. All the water on Earth's surface, including oceans, lakes, rivers, and glaciers.
20. Drift The gradual movement of continents across the Earth's surface over geological time.

1. A broad area of flat or gently rolling land with minimal elevation changes.
2. The regions of Earth where living organisms exist, encompassing land, water, and air.
4. An opening in Earth's crust where molten rock, ash, and gases erupt.
5. Molten rock that reaches the Earth's surface during a volcanic eruption.
8. A low area of land between hills or mountains, often with a river running through it.
10. The thick layer of solid and molten rock beneath the Earth's crust.
15. A sudden shaking of the ground caused by the movement of tectonic plates.
16. Tectonics The theory explaining the movement of large pieces of the Earth's crust over the mantle.
19. The process by which soil and rock are worn away and moved elsewhere by wind, water, or ice.
