Weathering, Erosion, and Deposition

Front

What is weathering?

Back

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

Front

What is erosion?

Back

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

Front

What is deposition?

Back

Deposition is the dropping of sediment that has been transported by water, wind, or ice.

Front

How do ocean waves contribute to erosion?

Back

Ocean waves wash away rocks and soil along the shore, gradually shaping the coastline.

Front

What role does freezing water play in 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 to new locations.

Front

What causes rocks to become smooth in a river?

Back

Rocks bumping and scraping against each other in a river smooth their edges.

Front

What is the main cause of mechanical weathering?

Back

Mechanical weathering is mainly caused by physical forces like freezing and thawing, or the growth of plant roots.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical breakdown of minerals in rocks, often due to water and acids.

Front

What is a glacier?

Back

A glacier is a large mass of ice that moves slowly over land, causing erosion and deposition.
