Soil, sand, and minerals washed from land into water usually after rain, that pile up in reservoirs, rivers, and harbors, destroying fish-nesting areas and clouding the water so that needed sunlight might not reach aquatic plants. Careless farming, mining, and building activities will expose sediment materials, allowing them to be washed off the land after rainfalls.
Particulate material, including soil, sand, and minerals, transported and deposited by water or wind (see erosion). Waterborne sediments cloud the water diminishing sunlight available to aquatic plants; sediments deposited in reservoirs, rivers, and harbors destroy fish and wildlife habitat and may fill shipping channels. Farming, mining, and building and construction activities that expose soil to wind and rain are major sources of sediments.
Sediments are loose, unconsolidated accumulations of mineral or rock particles that have been transported by wind, water, or ice, or shifted under the influence of gravity, and redeposited. Sediments can also be materials that precipitated, either chemically or biologically, from chemicals dissolved in water.
a complex mixture of materials transported by flowing water that eventually settles and accumulates
Particulate organic and inorganic matter that accumulates in a loose unconsolidated form. It may be chemically precipitated from solution; secreted by organisms; transported by air, ice, wind, or water; or washed off the land after rainfalls and deposited.
layers. In geology, rocks that are created through the repeated deposition of soils (sand, mud, etc.) are called sedimentary rock. Sandstone and slate are good examples.
the matter, such as soils, sand and rocks, that settles or is deposited on the bottom of a water body by the action of water, wind or glaciers.
Small pieces of rocks, shells, or the remains of plants and animals that have been carried along and deposited by wind, water, or ice.
Materials that form as a direct result of the weathering of rocks. Often they are transported to accumulate in another location, forming a deposit.
fragments of material produced by weathering and erosion of rocks
particles deposited by wind or water.
small particles of rock usually transported and deposited by water.
