Explain the characteristics and formation of deposition landforms including levees, flood plains and estuaries.

Deposition landforms such as levees, flood plains, and estuaries are created through the accumulation of sediment transported by rivers. Levees form along riverbanks as sediment is deposited during flooding events, raising the bank height. Flood plains are flat areas adjacent to rivers that are periodically inundated, allowing sediment to settle and enrich the soil. Estuaries occur where rivers meet the sea, leading to the deposition of sediment as the river's velocity decreases. Understanding these processes helps explain how landscapes evolve and the ecological significance of these areas.
