Weathering & Erosion

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces.

Front

What does wind carry that causes weathering?

Back

Wind carries sand, which can wear down rocks.

Front

What is mechanical weathering?

Back

Mechanical weathering is the process of breaking rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

Chemical weathering involves changes in the minerals of rocks due to chemical reactions, often involving water.

Front

What is erosion?

Back

Erosion is the process that moves small pieces of Earth's surface to another location.

Front

What is deposition?

Back

Deposition is the process where sediments are laid down in new locations after being transported by erosion.

Front

How does sunlight cause weathering?

Back

Sunlight can cause expansion and contraction in materials, leading to cracks and breaking.

Front

What role does water play in weathering?

Back

Water can cause both mechanical and chemical weathering by freezing and thawing or by dissolving minerals.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves those broken pieces to new locations.

Front

Can plants cause weathering?

Back

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