Sediments can be carried from one place to another. The movement of sediments by wind, water, ice, or gravity is called erosion. The process of dropping sediments in a new location is called deposition.

Sediments transported and deposited by glacial ice are known as till. Subglacial sediment (e.g., lodgement till) is material that has been eroded from the underlying rock by the ice, and is moved by the ice. These sediments form lateral moraines (Figure 16.1) and, where two glaciers meet, medial moraines.

Debris in the glacial environment may be deposited directly by the ice (till) or, after reworking, by meltwater streams (outwash). The resulting deposits are termed glacial drift. The resulting deposit is called a flow-till by some authors. …

Erosion can move sediment through water, ice, or wind. Water can wash sediment, such as gravel or pebbles, down from a creek, into a river, and eventually to that river’s delta. Deltas, river banks, and the bottom of waterfalls are common areas where sediment accumulates.

Sources of sediment are then defined as a combination of geomorphic elements and human uses (i.e. streambanks, upland cropland, pastured gullies, and forests).

It consists of two processes which always act together: fragmentation (known as mechanical or physical weathering) decay (known as chemical weathering)

Sedimentation, or clarification, is the processes of letting suspended material settle by gravity. Sedimentation is accomplished by decreasing the velocity of the water to a point which the particles will no longer remain in suspension.

Sedimentation techniques use solutions of lower specific gravity than the parasitic organisms, thus concentrating the latter in the sediment. Sedimentation techniques are recommended for general diagnostic laboratories because they are easier to perform and less prone to technical errors.

Sedimentary processes, namely weathering, erosion, crystallization, deposition, and lithification, create the sedimentary family of rocks.

Water Erosion

The physical processes on Earth create constant change. These processes—including movement in the tectonic plates in the crust, wind and water erosion, and deposition—shape features on Earth’s surface.

Explanation: The four common Planet Surface Processes are: Cratering, Volcanoes, Erosion, and Weathering (chemical and physical). Accretion, collisions and radioactive decay would be required in the formation.

Natural processes are interactions among plants, animals, and the environment. These interactions, which include photosynthesis , pollination, decomposition , and others, help create and shape natural communities .
