Explain how a river delta is formed, identifying which parts of the process are constructive and which are destructive.
How they are made: When the river reaches a slower-moving body of water, it drops the sediment (deposition). This buildup of new land is the constructive process that forms the delta.
Destructive: The river acts as a destructive force (erosion) higher upstream, where it breaks down rock and carries sediment away.
Constructive: When the river reaches a slower-moving body of water, it drops the sediment (deposition). This buildup of new land is the constructive process that forms the delta.
