Weathering, Erosion, & Deposition

Front

What is Weathering?

Back

Weathering is the process that breaks down rocks 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 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 after being transported by erosion.

Front

How do plant roots contribute to Weathering?

Back

Plant roots can grow into cracks in rocks, exerting pressure and causing the rocks to split apart, which is a form of weathering.

Front

What role does water play in Erosion?

Back

Water can carry away soil and rocks, especially during heavy rains or floods, leading to erosion of the land.

Front

Can you give an example of Deposition?

Back

An example of deposition is when a river slows down and drops off sand and gravel at its mouth, forming a delta.

Front

What is the difference between Weathering and Erosion?

Back

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

Front

What natural forces can cause Erosion?

Back

Natural forces that cause erosion include water, wind, ice, and gravity.

Front

What is an example of physical Weathering?

Back

An example of physical weathering is freeze-thaw action, where water seeps into cracks, freezes, expands, and causes the rock to break apart.

Front

How does human activity contribute to Erosion?

Back

Human activities like deforestation, construction, and farming can increase erosion by removing vegetation that holds soil in place.
