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.

What is mechanical weathering?

Back

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

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often leading to the formation of new minerals.

What is biological weathering?

Back

Biological weathering occurs when living organisms, such as plants and animals, contribute to the breakdown of rocks.

Front

What is abrasion in the context of weathering?

Back

Abrasion is a type of mechanical weathering that occurs when rocks and sediments grind against each other, often due to wind or water movement.

Front

What is salt weathering?

Back

Salt weathering is a type of mechanical weathering that occurs when salt crystals form in the pores of rocks, causing them to break apart.

How does the speed of a stream affect sediment transport?

Back

As the speed of a stream increases, it can carry larger amounts of sediment and larger particle sizes.

Front

What factors influence sediment deposition in a stream?

Back

Sediment deposition in a stream is influenced by the speed of the water, the size of the particles, and the slope of the streambed.
