Weathering and Erosion

Front

What is erosion?

Back

Erosion is the process that picks up and moves weathered rocks and soil from one place to another.

Front

What is a glacier?

Back

A glacier is an enormous mass of ice moving over land, causing weathering of rock and soil.

Front

What are sand dunes an example of?

Back

Sand dunes are an example of deposition.

Front

What is weathering?

Back

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

Front

What causes weathering when wind blasts sand at rock?

Back

This process is called weathering.

Front

What is deposition?

Back

Deposition is the process by which water, ice, wind, or gravity deposits rock sediments and soil in a new place.

Front

What role does gravity play in erosion?

Back

Gravity helps move fragments of rock and soil downhill, contributing to erosion.

Front

How does water contribute to weathering?

Back

Water can break down rocks through processes like freeze-thaw cycles and chemical reactions.

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

What is an example of mechanical weathering?

Back

An example of mechanical weathering is when water freezes in cracks of rocks and expands, causing the rock to break.
