Weathering, Erosion, and Deposition

Front

What is Erosion?

Back

The process of moving sediment by wind, water, ice, or gravity.

Front

What is Weathering?

Back

Any process that breaks down rocks without changing their chemical composition.

Front

What is Mechanical Weathering?

Back

A type of weathering that breaks down rocks into smaller pieces without altering their chemical structure.

Front

What is Deposition?

Back

The process in which eroded sediment is dropped and added to a landform or land mass.

Front

How do glaciers contribute to erosion?

Back

Glaciers carve U-shaped mountain passes through the process of erosion.

Front

What happens to rocks in a river over time?

Back

Rocks grind along the bottom of a river, making them smooth through weathering.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves the broken pieces away.

Front

What is an example of chemical weathering?

Back

The process of rocks reacting with water or acids, changing their chemical composition.

Front

What role does gravity play in erosion?

Back

Gravity pulls sediment downhill, contributing to erosion.

Front

What is the impact of wind on erosion?

Back

Wind can carry small particles of soil and sand, leading to erosion.
