Weathering and Erosion

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces through physical, chemical, or biological means.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What is an example of physical weathering?

Back

An example of physical weathering is when water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart.

Front

What is an example of chemical weathering?

Back

An example of chemical weathering is when acid rain reacts with minerals in rocks, leading to their dissolution.

Front

What role does water play in weathering?

Back

Water can cause both physical and chemical weathering; it can freeze in cracks to break rocks apart and can also dissolve minerals.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass.

Front

How does wind contribute to erosion?

Back

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

Front

What is the difference between weathering and erosion?

Back

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

Front

What is an example of erosion caused by water?

Back

An example of erosion caused by water is a river cutting through rock and soil, creating a canyon over time.

Front

What is the impact of vegetation on erosion?

Back

Vegetation helps to reduce erosion by stabilizing the soil with roots and absorbing water.
