Weathering and Erosion Test

Front

What is Physical Weathering?

Back

Physical Weathering is the process where rock breaks down into smaller rock and minerals without changing its chemical composition.

Front

What are two common causes of Mechanical Weathering?

Back

Water and ice are two common causes of Mechanical Weathering.

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 Soil?

Back

Soil is a loose mixture of rock fragments, organic material, water, and air that can support the growth of vegetation.

Front

What is Oxidation?

Back

Oxidation is a chemical reaction that occurs when a substance combines with oxygen.

Front

What is Chemical Weathering?

Back

Chemical Weathering is the process that breaks down rocks through chemical changes, often involving water and substances dissolved in it.

Front

What is an example of Mechanical Weathering?

Back

An example of Mechanical Weathering is ice wedging, where water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart.

Front

What role does water play in weathering?

Back

Water contributes to both physical and chemical weathering by breaking down rocks through freezing and thawing cycles and by dissolving minerals.

Front

What is the difference between Weathering and Erosion?

Back

Weathering is the breakdown of rocks in place, while Erosion involves the movement of those broken materials from one location to another.

Front

What is the impact of vegetation on soil erosion?

Back

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