Weathering and Erosion

Front

What is Weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through natural forces like wind, water, and temperature changes.

Front

What is Erosion?

Back

Erosion is the movement of soil and rock from one location to another, often caused by water, wind, or ice.

How does wind contribute to weathering?

Back

Wind can blast sand at rocks, causing them to break down and form features like arches.

Front

What role does water play in erosion?

Back

Water can carry soil and sediment away from one place and deposit it in another, reshaping the landscape.

Front

What is a Delta?

Back

A delta is a landform that forms at the mouth of a river where it meets a body of water, created by the deposition of sediment.

Front

How does freezing water cause weathering?

Back

Freezing water expands in cracks of rocks, causing them to break apart.

Front

What is the difference between weathering and erosion?

Back

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

Front

Can plants cause weathering?

Back

Yes, plant roots can grow into cracks in rocks, causing them to break apart over time.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown 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.
