Weathering and Erosion

Front

What is weathering?

Back

Weathering is the process where rocks break down into smaller pieces or minerals due to natural forces like wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the movement of sediment from one place to another by natural forces such as water, ice, gravity, and wind.

Front

What is deposition?

Back

Deposition is the process where sediment is dropped or deposited in a new location after being transported by erosion.

Front

What is a slow land change?

Back

A slow land change is a change that takes a long time, such as the gradual wearing away of rocks.

Front

What is an example of erosion?

Back

An example of erosion is sand being pulled away from a beach by waves.

Front

What causes weathering?

Back

Weathering is caused by natural elements like water, ice, temperature changes, and biological activity.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks into smaller pieces, while erosion moves those pieces to a new location.

Front

What role does gravity play in erosion?

Back

Gravity helps move sediment downhill, contributing to erosion, especially in landslides and riverbanks.

Front

How do plants contribute to weathering?

Back

Plants contribute to weathering by their roots breaking apart rocks as they grow.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breaking down of rocks without changing their chemical composition.
