Weathering, Erosion & Deposition

What is weathering?

• occurs when the eroded materials are dropped or laid down

• fragments of weathering rocks

• the process by which rock materials are broken down by the action of physical and chemical process

• the process by which wind, water, ice or gravity transport weathered materials from one location to another

• erosion

• deposition

What are glaciers?

• They are winding rivers that carry sediment to a delta

• They are waves that constantly crash against the shoreline.

• are huge masses of ice that move slowly over land.

• They are sand dunes that form from wind depositing sediments.
