Terrigenous sediments are materials that originate from land and are transported to oceans and lakes by processes such as erosion, river flow, and wind. These sediments primarily consist of particles like sand, silt, and clay, which are derived from rocks and soil. They play a crucial role in shaping marine environments and can influence the habitats of various aquatic organisms. Once these sediments reach water bodies, they settle on the seabed or lake floor, forming layers over time. The composition of terrigenous sediments can vary based on the surrounding geology and climate, impacting the marine ecosystem and the geological history of the area.
