What is erosion?

Back

Erosion is the removal and transport of material from one location to another by natural forces such as wind, water, or ice.

What role does water play in mechanical weathering?

Back

Water contributes to mechanical weathering through temperature changes, causing rocks to expand and contract, leading to cracks.

Front

What is till?

Back

Till is unsorted rocks and sediments left behind when a glacier melts.

What is deflation in the context of erosion?

Back

Deflation is the process by which wind removes loose particles from the ground, often leading to the smoothing of rocks.

Front

True or False: Waves erode cliffs only through the force of their pounding.

Back

False. Waves can also erode cliffs through chemical processes and the movement of sediment.

Front

What is the main cause of erosion by water?

Back

The main cause of erosion by water is the movement of water, which can carry sediments and shape landscapes.

What is chemical weathering?

Back

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

How does temperature affect weathering?

Back

Temperature changes can cause rocks to expand and contract, leading to physical weathering and the formation of cracks.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken materials.
