2. Not all soils are the same. Because soils are made from weathered rock fragments, the types of soil that forms depends on the type of rock that weathers.

4. Sometimes, the bedrock is the parent rock if the soil above it formed from the bedrock below. Soil that remains above its parent rock is called residual soil.

8. The upper part of the wave moves more rapidly and grows taller, and begins to curl and break. These breaking waves are known as surf.

11. Breaking waves also wash away fine grains of sand, which are picked up by the waves and wear down and polish coastal rock.

13. Sea cliffs are formed when waves erode and undercut rock to produce steep slopes.

17. Waves carry a variety of materials, including sand, rock fragments, dead coral, and shells.

20. A sandbar is an underwater or exposed ridge of sand, gravel, or shell material.

27. Continental glaciers smooth the landscape by scraping and eroding features that existed before the ice appeared.

32. Streams carry sorted material and deposit it in front of the glacier in a broad area called an outwash plain.
