Earth Science Unit 3 Lesson 1

4. Group of interacting parts forming a unified whole.
5. All water cycling liquid, vapor, and ice forms.
8. Related component working within the larger Earth system.
9. Sudden downward movement of rock and soil along a slope driven by gravity.
10. Rapid geologic event where overflowing water erodes and deposits sediment in hours or days.
12. Layer of surrounding gases driving weather and climate.
13. The removal and transport of sediment, which can happen rapidly during heavy floods.
16. Organism that produces chemicals to break down rocks on a small scale.
17. Landform created by sediment deposited at the mouth of a river over months or years.
18. Drives erosion and deposition processes to transfer matter across Earth's surface.
19. Geological feature driven by internal heat and magma.
20. The makeup or substances that determine how resistant a rock is to breakdown.
23. Global-scale movement of Earth's crustal plates that shapes ocean basins and mountain chains.
24. Underground water containing natural acids that can dissolve rock to form caves.

1. All living organisms, from bacteria to giant trees.
2. Includes rocks, minerals, landforms, and Earth's interior.
3. Large mass of ice that exists year-round and flows slowly over land.
6. Interacting parts of Earth whose complex relationships drive surface changes over time.
7. Chemical process, such as reactions with oxygen and water, that breaks down minerals in rocks.
11. Occurs when eroded materials are dropped or laid down somewhere new.
12. Scraping of rock surfaces by other materials carried by wind, water, ice, or gravity.
14. Force pulling water downward to carve landform features.
15. Fragments of weathered rock that build up to form soil, rock formations, and sand dunes.
21. Fast-flowing body of water that tumbles rocks and carries sediment downstream.
22. Very small space scale of geologic change, such as the formation of crystals.
