Layers of sediment

Layers of sediment refer to distinct levels of soil or rock formed by the accumulation of materials over time, such as sand, silt, clay, and organic matter. These layers are created by natural processes like erosion, weathering, and deposition from water, wind, or ice. As new material settles on top of older layers, each layer can preserve a record of past environments and life. Scientists study these layers to understand Earth's history, including climate changes and the evolution of species, making sedimentary layers valuable for both geological research and natural resource exploration.
