___________ is the process of wind, water or other factors breaking rock down. This is most likely to happen on the surface of the rock where the rock comes into contact with air and water.

• Erosion
• Weathering
• Deposition
• Rock Cycle

What is deposition?

• Pieces of sediment come to rest on a surface

• Movement of sediment

• Breaking down of sediment 

 Deposition is a process that

• Dissolves sediment

• Breaks down rock to form sediment

• Removes sediment from land forms

• Drops sediment to form landforms

Where do deltas form?

• Desert Areas

• At river mouths

• On the Banks of Rivers

• In Valleys Formed by Glaciers

The course or path of a river is called:
