Weathering, Erosion & Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks 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.

How do waves affect beaches?

Back

Waves deposit and wash away sand, changing the shape and size of the beach over time.

Front

What role do plants and lichens play in weathering?

Back

Plants and lichens contribute to weathering by breaking down rocks physically and chemically through their growth and metabolic processes.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle, which is broken into tectonic plates.

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer beneath the lithosphere that allows tectonic plates to move.

Front

What is the core of the Earth?

Back

The core is the innermost layer of the Earth, consisting of a solid inner core and a liquid outer core, and is the densest layer.

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 different location.

Front

What is chemical weathering?

Back

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