Sedimentation is the process by which particles settle out of a fluid, such as water or air, and accumulate on a surface. This natural phenomenon plays a crucial role in shaping landscapes, forming sedimentary rocks, and creating habitats for various organisms. Factors like gravity, water flow, and wind influence how and where sediment is deposited. In aquatic environments, sedimentation can lead to the formation of river deltas and lake beds. Over time, layers of sediment can compact and cement together, resulting in rock formations like sandstone and shale. Understanding sedimentation is essential for fields like geology and environmental science as it impacts ecosystems and natural resources.
