Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice, and/or by the force of gravity acting on the particles.ivers and streams carry sediment in their flows. This sediment can be in a variety of locations within the flow, depending on the balance between the upwards velocity on the particle (drag and lift forces), and the settling velocity of the particle.
Sediment is any material deposited on the earth's surface that is derived from rocks by weathering. The products of weathering include rock fragments (detritus), new minerals, such as kaolinite and hematite, and dissolved ions, which may later precipitate from water.. Detrital sedimentary rocks: These rocks are composed of mineral grains and/or rock fragments transported and deposited by some geologic agent. Detrital rocks are typically composed of mineral grains derived from silicate rocks.
