Weathering, Erosion, and Deposition Flashcard

Front

What is the main difference between mechanical and chemical weathering?

Back

Mechanical weathering breaks rocks into smaller pieces without changing their chemical composition, while chemical weathering changes the chemical composition of rocks.

Front

How does the size of a rock or particle affect how fast it erodes?

Back

Smaller pieces erode faster.

Front

What are the main causes of erosion?

Back

Water, wind, ice, and gravity

Front

How do weathering, erosion, and deposition work together to change the Earth's surface?

Back

They create landforms like valleys and deltas.

Front

How do human activities affect erosion and deposition?

Back

They can increase erosion and deposition through activities like farming and construction.

Front

How do rivers shape the land through erosion and deposition?

Back

They create landforms like valleys and deltas.

Front

What are glaciers, and how do they cause erosion?

Back

Glaciers are large masses of ice that move and shape the land by carrying rocks and soil.

Front

How does wind shape the land in deserts?

Back

Wind creates landforms like sand dunes through erosion and deposition.

Front

What factors can make soil erode more quickly?

Back

Weather, plants, and human activity can increase soil erosion.

Front

Why is deposition important for building new landforms?

Back

Deposition creates features like beaches and river deltas by accumulating sediment.
