sediments in environmental science

Sediments are tiny particles of soil, minerals, and organic matter that accumulate in places like rivers, lakes, and oceans. They originate from natural processes such as weathering and erosion, where rocks and soil are broken down and transported by water, wind, or ice. Sediments can influence water quality, habitat health, and the movement of nutrients and pollutants. They play a key role in shaping landscapes and forming natural features like deltas and beaches. Understanding sediments helps scientists assess environmental health, track pollution sources, and manage land and water resources effectively.
