Lesson 1 to 3 Review

4. The breakdown of rocks through chemical changes.
8. A tall column of rock isolated from the shore by wave erosion.
10. All the water on Earth, including oceans, lakes, rivers, and groundwater.
12. The frozen water part of Earth, including glaciers and ice caps.
13. The two things that move between different spheres.
15. Water found underground in the cracks and spaces in soil, sand, and rock.
16. Rain or snow that contains acids from air pollution and breaks down rocks.
17. A chemical reaction where a material combines with oxygen, often causing rust.
20. The movement of sediment or rock by wind, water, ice, or gravity.

1. Breaking down of rocks into smaller pieces without changing their composition.
2. Type of physical weathering where water freezes in cracks, expanding and breaking rock.
3. Curving bends in a river formed as water erodes the outer banks and deposits sediment on the inner banks.
5. The solid part of Earth, including rocks and landforms.
6. The two things that move between different spheres.
7. The boundary where land meets a body of water.
9. Way to keep track of energy transfers into and out of Earth's systems.
11. All living things on Earth.
14. Factor that influences how much erosion can occur based on the steepness of the slope.
18. The layer of gases that surrounds Earth.
19. The dropping or settling of eroded material.
