What is Erosion?

Back

The process in which wind, water, ice, or gravity transport rock fragments from one location to another.

Front

What is Mechanical Weathering?

Back

The process where physical forces break down rocks without changing their chemical composition, such as wind blowing sand onto rocks.

Front

How does freezing water cause weathering of rocks?

Back

Freezing water expands in cracks and makes rock break.

Front

What is a mutualistic relationship?

Back

A type of symbiotic relationship where both species benefit, such as a bird eating insects off a rhinoceros.

Front

What is Chemical Weathering?

Back

The process that breaks down rocks through chemical reactions, such as acid rain wearing away rock over time.

Front

What is Deposition?

Back

The process by which sediments, soil, and rocks are added to a landform or land mass.

Front

What is Sedimentation?

Back

The process of settling or being deposited as sediment, often in bodies of water.

Front

What is the difference between Erosion and Weathering?

Back

Erosion involves the movement of rock fragments, while weathering is the breaking down of rocks in place.

Front

What is an example of physical weathering?

Back

The breaking of rocks into smaller pieces without changing their chemical composition, such as freeze-thaw cycles.

Front

What is an example of chemical weathering?

Back

The process of acid rain reacting with minerals in rocks, leading to their breakdown.
