4th Grade Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces due to natural forces like wind, water, and ice.

Front

What is erosion?

Back

Erosion is the movement of sediments from one place to another, often caused by water, wind, or ice.

Front

What is deposition?

Back

Deposition is the dropping off of sediments in a new location after being transported by erosion.

Front

How does ice cause weathering?

Back

Ice can freeze in the cracks of rocks, expanding and causing the rocks to break apart.

Front

What role does water play in soil formation?

Back

Water helps to break down rocks into small pieces, which contributes to the formation of soil.

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

How do waves affect the shape of a riverbank?

Back

Waves can erode the bank of a river, changing its shape over time.

Front

What is an example of mechanical weathering?

Back

An example of mechanical weathering is rocks bumping and scraping against each other in a river.

Front

What is chemical weathering?

Back

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

Front

How does wind contribute to erosion?

Back

Wind can carry small particles of sand and dust, eroding surfaces as it moves.
