Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process that breaks down rocks and other materials on Earth's surface into smaller pieces.

Front

What is erosion?

Back

Erosion is the process by which soil and sediment (weathered rock) are transported (moved) from one place to another by water, wind, glaciers, and gravity.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often forming new land features.

Front

How do humans increase erosion?

Back

Humans increase erosion by building on land, which can disturb the soil and make it more susceptible to being washed or blown away.

Front

What can result from long-term deposition?

Back

Over long periods of time, deposition may change the Earth’s surface by forming new land features.

Front

What is an example of erosion?

Back

A farmer's topsoil being blown away during a hurricane is an example of erosion.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks into smaller pieces, while erosion transports those pieces from one location to another.

Front

What role does gravity play in erosion?

Back

Gravity helps move soil and sediment downhill, contributing to erosion.

Front

What natural forces can cause erosion?

Back

Natural forces that can cause erosion include water, wind, glaciers, and gravity.

Front

What is the impact of erosion on landscapes?

Back

Erosion can change landscapes by removing soil and rock, leading to features like valleys and canyons.
