sediments

Sediments are particles of mineral and organic material that settle and accumulate over time, often transported by water, wind, or ice. They can include sand, silt, clay, pebbles, and biological debris. Sediments build up to form layers of sedimentary rocks through compaction and cementation. They also play a crucial role in shaping landscapes, creating habitats, and preserving fossils. Sediments vary in size, composition, and origin, and understanding them helps geologists learn about Earth's history, climate changes, and natural processes.
