Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces by natural forces such as water, ice, and temperature changes.

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 water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often occurring at the mouth of rivers or on beaches.

Front

How does water contribute to weathering?

Back

Water can enter cracks in rocks, freeze, and expand, causing the rocks to break apart.

Front

What role do rivers play in erosion?

Back

Rivers can carry away mud, soil, and rocks, effectively eroding the land as they flow.

Front

What happens during deposition at the ocean floor?

Back

Sediments settle and accumulate at the bottom of the ocean, forming layers over time.

Front

Can weathering occur without erosion?

Back

Yes, weathering can occur independently of erosion; rocks can break down without being transported.

Front

What is an example of mechanical weathering?

Back

An example of mechanical weathering is rocks being smoothed by tumbling in a stream.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to reactions with water or acids.

Front

How do waves contribute to deposition?

Back

Waves can carry sand and other materials and deposit them on beaches, reshaping the shoreline.
