What is the main cause of erosion and deposition by water?
Erosion is the process of water wearing away the land, removing sediments and particles. Deposition is when the water slows down and drops the sediments and particles it was carrying. Both erosion and deposition shape and change the landscape over time.
Erosion and Deposition by Water
Erosion is the process by which water wears away the land, usually through its movement in streams or rivers. Deposition is the process by which water leaves behind sediment in new areas, such as sandbars or levees. Floodplain is an area of land that is prone to flooding along a river or stream, and is often shaped by the erosion and deposition of water over time.
Erosion and deposition by water is responsible for the formation of many natural features such as deltas, meanders, oxbow lakes, and floodplains. In some cases, the rock that is eroded is carried away, and then deposited elsewhere in the form of sedimentary rock. The process of erosion and deposition is so slow that it's often hard to see changes over short time periods, but over thousands of years it can reshape entire landscapes.

Question: What are the different ways in which water can cause erosion and deposition? Clues: • Erosion is when water uses its energy to move material from one place to another. • Deposition is when water drops the material it was carrying. • Water can erode and deposit materials through its different processes such as flooding, stream flow, and ocean currents. In pairs: Select and solve one of the tasks: A. Work in pairs and draw a diagram that illustrates the different ways in which water can cause erosion and deposition. B. Explain your diagram to your partner and explain how each process works.
