Weathering and Erosion

Front

What is erosion?

Back

Erosion is the process by which water, ice, and wind move particles of rock and soil from one place to another.

Front

What is weathering?

Back

Weathering is the breaking down of Earth’s crust into smaller and smaller pieces.

Front

What is deposition?

Back

Deposition is the placement of rocks and soil after they have been broken down and moved.

Front

What causes erosion?

Back

Erosion is caused by natural forces such as water, wind, and ice.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken pieces.

Front

Can erosion happen without weathering?

Back

No, erosion cannot happen without weathering because the materials need to be broken down first.

Front

What role does gravity play in erosion?

Back

Gravity helps to pull rocks and soil down slopes, contributing to erosion.

Front

Give an example of weathering.

Back

An example of weathering is when rainwater seeps into cracks in rocks and freezes, causing the rocks to break apart.

Front

What is mechanical weathering?

Back

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

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to reactions with water or acids.
