What is erosion?

Back

The geological process where rocks or sediments are moved or transported from one place to another, often by water, wind, or ice.

What is deposition?

Back

When eroded materials are dropped or laid down in a new location, forming new landforms.

How does a river erode sediment?

Back

A river erodes sediment by flowing water that carries away particles from the riverbed and banks.

What happens to sediment when a river slows down?

Back

The river loses energy and drops sediment, leading to deposition.

Front

What are glaciers?

Back

Huge masses of ice that move slowly over land, eroding and transporting sediment.

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.

What role does water play in weathering?

Back

Water can cause chemical weathering by reacting with minerals, and physical weathering through freeze-thaw cycles.
