Weathering, Erosion, Deposition

Front

What is weathering?

Back

Weathering is the process that breaks 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 the Earth's surface by wind, water, or ice and transported to another location.

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

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 physical weathering?

Back

Physical weathering is the process of breaking down rocks without changing their chemical composition, often through temperature changes, freeze-thaw cycles, or abrasion.

Front

What is chemical weathering?

Back

Chemical weathering involves the alteration of the mineral composition of rocks through chemical reactions, such as oxidation or hydrolysis.

Front

What is frost wedging?

Back

Frost wedging is a type of physical weathering where water seeps into cracks in rocks, freezes, expands, and eventually causes the rock to break apart.

Front

What factors influence erosion?

Back

Factors that influence erosion include vegetation cover, water flow speed, and the amount of water present.

Front

How does vegetation affect erosion?

Back

Vegetation helps to anchor soil in place, reducing the likelihood of erosion by water or wind.

Front

What is the role of water in erosion?

Back

Water can erode land by carrying away soil and rock particles, especially during heavy rainfall or flooding.
