Weathering, Erosion, Deposition

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 Deposition?

Back

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

Front

How does water contribute to Weathering?

Back

Water can cause weathering through processes like freeze-thaw cycles, where water seeps into cracks, freezes, expands, and breaks the rock apart.

Front

What role do glaciers play in Erosion and Deposition?

Back

Glaciers erode the landscape by scraping and carrying away rocks, and when they melt, they deposit the materials they carried.

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 is an example of physical Weathering?

Back

An example of physical weathering is the cracking of rocks due to temperature changes, such as heating and cooling.

Front

What is an example of chemical Weathering?

Back

An example of chemical weathering is the reaction of acid rain with limestone, which dissolves the rock.

Front

What is an example of Erosion by wind?

Back

An example of erosion by wind is the formation of sand dunes, where wind moves sand particles from one place to another.

Front

What is an example of Deposition?

Back

An example of deposition is the formation of deltas at river mouths, where sediment is deposited as the river slows down.
