Back

The correct order is weathering, erosion, and deposition.

Front

Back

Deltas are typically located at the mouth of a river.

Front

What shape do deltas usually have?

Back

Deltas usually have a triangular shape.

Front

What role does water play in delta formation?

Back

Water helps transport sediments from the river to the delta, where they are deposited.

Front

How do deltas benefit the environment?
