Weathering & 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 process that moves small pieces of Earth's surface from one place to another, often caused by water, wind, or ice.

Front

What causes a mudslide?

Back

A mudslide is a fast erosion event caused by moving water and gravity, often occurring after heavy rain.

Front

What is deposition?

Back

Deposition is the process where eroded materials are dropped off in a new location, forming new landforms.

Front

How does water contribute to erosion?

Back

Water can wear away rocks and soil as it flows, carrying away particles and reshaping the landscape.

Front

What role does wind play in erosion?

Back

Wind can pick up and carry small particles of sand and soil, leading to erosion, especially in dry areas.

Front

What is the Grand Canyon primarily formed by?

Back

The Grand Canyon was largely formed by the erosion caused by the Colorado River over millions of years.

Front

What is expansion and contraction?

Back

Expansion and contraction refer to the process where materials like rocks expand when heated by the sun and contract when cooled, causing cracks.

Front

What natural forces can cause erosion?

Back

Water, wind, and ice are all natural forces that can cause erosion.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks into smaller pieces, while erosion moves those pieces to a different location.
