Final answer:
Sedimentation occurs when the energy of the water decreases and sediment gets deposited. This happens as rivers and streams flow away from their source, causing the current to slow down and allowing sediment to settle.
Step-by-step explanation:
Sediment deposition when the energy of the water decreases is called sedimentation. It occurs as rivers and streams flow away from their source and the width of the channel widens, causing the current to slow down. The slower-moving water leads to the settling of sediment. For example, as waves reach the shore, the depth decreases and the wave energy is compressed, resulting in sediment deposition and the formation of higher waves.
Sedimentation features are geological formations resulting from the deposition and accumulation of sediments over time. These features provide insights into past environmental conditions and geological processes, offering valuable information for understanding Earth's history and dynamic landscape evolution.
