Earth's spheres/Weathering, erosion, deposition

Front

What is physical weathering?

Back

Physical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition, often through mechanical forces like freezing and thawing.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often through reactions with water, acids, or gases, leading to the formation of new minerals.

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 when the transporting medium loses energy.

Front

How does water contribute to erosion?

Back

Water contributes to erosion by flowing over land, carrying away soil and sediment, and reshaping landscapes through processes like river flow and rainfall.

Front

What role do plants play in weathering?

Back

Plants can contribute to weathering by breaking down rocks through root growth and by producing organic acids that chemically alter minerals.

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 the dissolution of limestone by acidic rainwater, which can create caves.

Front

What is the difference between erosion and deposition?

Back

Erosion involves the removal and transport of materials, while deposition is the accumulation of those materials in a new location.

Front

What is sediment?

Back

Sediment refers to small particles of rock, minerals, and organic material that are transported by wind, water, or ice.
