ocean sediment

Ocean sediment consists of particles that settle at the bottom of the ocean, including tiny shells, volcanic ash, biological debris, and minerals. These sediments accumulate over time, forming layered deposits that record Earth's history. The composition varies by location, influenced by nearby land, biological activity, and ocean currents. Sediments are important for studying past climates, supporting marine life, and exploring natural resources like fossils or minerals. They also play a crucial role in the Earth's carbon cycle, helping regulate global climate by storing carbon in deep ocean layers.
