Sediment 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.ediment is transported based on the strength of the flow that carries it and its own size, volume, density, and shape. Stronger flows will increase the lift and drag on the particle, causing it to rise, while larger or denser particles will be more likely to fall through the flow.

Rocks Sedimentary rocks are formed from eroded fragments of other rocks or even from the remains of plants or animals. The fragments accumulate in low-lying areas—lakes, oceans, and deserts—and then are compressed back into rock by the weight of overlying materials.

What are sediments? Rockhound. Sediments in geology are solid fragments of inorganic or organic material that come from the weathering of rock or biological processes and are carried and deposited by wind, water, or ice. Sediments are types of rock that are formed by the deposition of material from the Earth's surface.There are different types of sediments rocks.ediments are tiny pieces of earth that travel by being carried by either wind, water, or ice. they are involved with the process of fossils since it covers and buries an orga … nism when it dies and eventually settle under great amounts of heat and pressure.

- Enjoy our sedimentary rock facts for kids. Find interesting information and a range of examples that help explain what sedimentary rocks are and what makes them different from other kinds of rocks. Sedimentary rocks are formed by sediment that is deposited over time, usually as layers at the bottom of lakes and oceans. This sediment can include minerals, small pieces of plants and other organic matter. The sediment is compressed over a long period of time before consolidating into solid layers of rock.

- An introduction to SEDIMENTARY ROCKS. Sedimentary rocks form from sediment. Sediment is a general term that indicates loose grains (such as the sand at the beach) and chemical precipitates (such as crystals of salt).Sedimentary rocks can be subdivided in three categories: clastic, chemical, and biochemical sedimentary rocks.ediment is a general term that indicates loose grains (such as the sand at the beach) and chemical precipitates (such as crystals of salt).

Marine sediment Marine sediment, any deposit of insoluble material, primarily rock and soil particles, transported from land areas to the ocean by wind, ice, and rivers, as well as the remains of marine organisms, products of submarine volcanism, chemical precipitates from seawater, and materials from outer space (e.g., meteorites) that accumulate on the seafloor.

- Consolidated sediments are sedimentary rocks, including conglomerate, sandstone, siltstone, shale, limestone, and coal. Geologic processes over time can fold, break, erode, and change (metamorphose) sedimentary rocks. Unconsolidated sediments are loose materials, ranging from clay to sand to gravel. Ground water flows through spaces between the grains. Geologic processes can likewise erode and metamorphose unconsolidated sediments. Earthquakes, for example, can liquefy unconsolidated sediments (but not consolidated sediments).

- Sedimentary rocks are formed by sediment that is deposited over time, usually as layers at the bottom of lakes and oceans. This sediment can include minerals, small pieces of plants and other organic matter. The sediment is compressed over a long period of time before consolidating into solid layers of rock. Sedimentary rocks forms layers called strata which can often be seen in exposed cliffs.

Sedimentary Rocks All rocks, once exposed on the surface of the Earth are subjected to processes of erosion, transportation and ultimately deposition. These topics are covered in detail in Geol. 201. For our current purposes, it is sufficient to state that such processes produce sediment which may ultimately be transformed into sedimentary rock. Sediment can be defined as any material that settles to the bottom of a fluid. Sedimentary rocks are classified in to three major categories based on the nature of the sediment. I. Detrital or Clastic Sediments These rocks are composed of fragments of pre-existing rock that have been eroded, transported and deposited in an accumulation that has subsequently been converted into a hard coherent sedimentary rock.

sedimentary Sedimentary rocks are formed from grains of minerals and rocks, dissolved minerals and other material, such as plant matter or animal remains, which have been transported and deposited as sediment.lant material can be found as fragments in sandstones or other sedimentary rocks, and if it makes up the bulk of the rock it is termed coal. The shells of many marine organisms are made of calcium carbonate, and form limestone or calcite-rich sediments such as marl (a calcareous mudstone).

Sedimentary rocks Sedimentary rocks. Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding.lastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.

- Sedimentary rocks are types of rock that are formed by the deposition of material at the Earth 's surface and within bodies of water.his sediment is often formed when weathering and erosion break down a rock into loose material in a source area. The material is then transported from the source area to the deposition area. The type of sediment transported depends on the geology of the hinterland (the source area of the sediment).

Sediment Sediments are most often transported by water (fluvial processes), wind (aeolian processes) and glaciers. Beach sands and river channel deposits are examples of fluvial transport and deposition, though sediment also often settles out of slow-moving or standing water in lakes and oceans. Desert sand dunes and loess are examples of aeolian transport and deposition.

What Is a Sedimentary Rock? Sediment is the sand you find at the beach, the mud in a lake bottom, the pebbles in a river, and even the dust on furniture. The sediment may, in time, form a rock if the little pieces become cemented together. There are other types of sedimentary rocks whose particles do not come from broken rock fragments.

Sedimentary rock Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water. Sedimentation is the collective name for processes that cause mineral and/or organic particles (detritus) to settle in place.

- Sedimentary rocks are types of rock that are formed by the deposition of material at the Earth 's surface and within bodies of water.lastic sedimentary rocks are composed of silicate minerals and rock fragments that were transported by moving fluids (as bed load, suspended load, or by sediment gravity flows) and were deposited when these fluids came to rest.

Sediment Transport and Deposition Sediment refers to the conglomerate of materials, organic and inorganic, that can be carried away by water, wind or ice 3. While the term is often used to indicate soil-based, mineral matter (e.g. clay, silt and sand), decomposing organic substances and inorganic biogenic material are also considered sediment 1.ediment transport is the movement of organic and inorganic particles by water 10. In general, the greater the flow, the more sediment that will be conveyed. Water flow can be strong enough to suspend particles in the water column as they move downstream, or simply push them along the bottom of a waterway 11.

Sedimentary Rocks: Depositional Environments and Structures Sediments are the end product of the destruction of preexisting rocks (igneous, metamorphic or sedimentary) on the earth's surface. The two major processes leading to decomposition of rocks are (1) mechanical breakage and (2) chemical dissolution.omposition, texture and color are important means of identifying sedimentary rock types, and the observation of sediment types in modern depositional settings is a key factor in identifying means of distinguishing ancient environments based on sedimentary rock types and facies associations.
