100
this is the breaking of rocks into smaller pieces without changing them chemically

Oxygen combines with iron in rock and soil. It forms iron oxide, or rust. Rust weakens the rock and makes it easier to break down. This is an example of what?
What is chemical weathering

Contour plowing, planting vegetation, and building windbreaks are all ways to prevent this
What is erosion

U-shaped valleys are often formed when this erodes rock and soil.
What are glaciers
400
weathered rock pieces, deposited by wind, water, or ice
What is sediment
400
What features are formed on coasts from deposition?
What are barrier islands
400
Water seeps into cracks in rocks. When water freezes into ice, it expands. If the water freezes inside these cracks, it helps break the rock apart like a wedge. Freezing and thawing of rock also helps break it down. This is an example of what?
