Loose materials formed when large rocks in the landscape are broken down and worn away are called sediment.
This breakdown or dissolution of large rocks on the Earth's surface is referred to as weathering. Agents of weathering include water, ice, acids, plants, animals, variations in temperature, etc. After the process of weathering, a process called erosion transports the pieces of rock and mineral away.
Sediment is a substance that is formed when rocks are broken down by weathering and erosion processes and then moved by the force of gravity acting on the particles or by the action of wind, water, or ice. Sediments can be classified on the basis of its size of grain, shape of grain, and composition.
