Weathering and Erosion

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 one location and transported to another, often by wind, water, or ice.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition. An example is ice wedging.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, leading to changes in their composition. An example is rusting.

Front

What is abrasion?

Back

Abrasion is the process of scraping or wearing away of rock surfaces through friction, often caused by wind or water carrying particles.

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass, often occurring in river deltas.

Front

What is oxidation in the context of weathering?

Back

Oxidation is a chemical weathering process where oxygen reacts with minerals, often leading to rust formation in iron-rich rocks.

Front

What is the role of tree roots in mechanical weathering?

Back

Tree roots can grow into cracks in rocks, exerting pressure and causing the rocks to break apart, which is an example of mechanical weathering.

Front

What is a destructive force in geology?

Back

A destructive force is a natural process that breaks down or removes landforms, such as erosion by rivers carving canyons.

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 new locations.
