Weathering & Erosion

Front

What is weathering?

Back

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

Front

What is erosion?

Back

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

Front

What role does water play in weathering?

Back

Water can cause weathering by freezing and thawing, which cracks rocks, and by carrying away small particles.

Front

How does wind contribute to erosion?

Back

Wind can carry sand and small rocks, which can wear away larger rocks and soil over time.

Front

What is the Grand Canyon an example of?

Back

The Grand Canyon is an example of a landform created by erosion, primarily by the Colorado River.

Front

What is a riverbed?

Back

A riverbed is the ground over which a river flows, often shaped by the running water that carves it out.

Front

What is the effect of ice on rocks?

Back

Ice can cause weathering by expanding in cracks of rocks when it freezes, leading to the rocks breaking apart.

Front

What are tree roots' role in weathering?

Back

Tree roots can grow into cracks in rocks, and as they grow, they can break the rocks apart.

Front

What is gravity's role in erosion?

Back

Gravity pulls rocks and soil down slopes, which can lead to erosion, especially during rain.

Front

What is sand?

Back

Sand is small particles of rock that can be carried by wind or water, contributing to weathering and erosion.
