What is the difference between Weathering and Erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken pieces.

Front

What role does Wind play in Erosion?

Back

Wind can carry small particles of sand and dust away from one area and deposit them in another.

What is Mechanical Weathering?

Back

Mechanical weathering is the physical breakdown of rocks without changing their chemical composition.
