Sediments are transported to new locations primarily through natural processes such as water, wind, and ice. In rivers and streams, flowing water erodes sediment from the landscape and carries it downstream. Wind can lift and move fine particles over long distances, while glaciers can drag and deposit sediments as they advance and retreat. Additionally, coastal processes like waves and currents can redistribute sediments along shorelines.
Sediments can change into sedimentary rocks through processes like compaction and cementation. They can also be eroded and transported to new locations by forces like wind and water.
Weathering and erosion break down rocks into smaller pieces called sediments. This process can happen through physical weathering (mechanical breakdown) or chemical weathering (decomposition of minerals). The resulting sediments can then be transported by wind, water, or ice to new locations.
Two processes that bring sediments to a new location are erosion, where sediments are broken down and transported by natural forces like water, wind, or ice, and sedimentation, where these sediments accumulate and settle in a new location, forming layers over time.
By water or wind
Common sediments produced by glaciers include till (unsorted mixture of rocks and sediment), moraine (deposits of till), outwash (sorted sediments deposited by meltwater), and glacial erratics (large boulders transported by glaciers from distant locations).
Sediments eroded from mountainsides and transported in streams are an example of the conservation of mass. The total amount of sediment that is eroded from the mountainside remains constant as it is transported by streams to other locations.
Sediments are small particles of soil or rocks that are transported by water or wind. They can vary in size from tiny clay particles to larger sand or gravel particles. Sediments can be carried downstream by rivers or blown by the wind to new locations where they may eventually settle and accumulate.

When rocks undergo weathering, they become smaller in size and break down into smaller pieces called sediments. These sediments can eventually be transported and deposited in new locations, where they may become compacted and cemented together to form sedimentary rocks.
Transported sediments are usually deposited at locations where the transporting medium's energy decreases, such as river deltas, beaches, and the mouths of rivers. The sediment settles out of the transporting medium and accumulates to form sedimentary deposits.

Weathering breaks down rocks into smaller pieces through physical, chemical, or biological processes. These smaller rock fragments, called sediments, are then transported by natural forces like wind, water, or ice and deposited in new locations. Over time, these sediments can accumulate and form sedimentary rocks.
The process by which sediment is removed from its source is called erosion. This can be caused by natural processes like wind, water, or ice, as well as human activities. Eroded sediment is then transported and deposited in new locations.
When waves erode through a cliff, they produce sediments such as sand, gravel, and rocks. These sediments can be carried away by the waves, deposited on beaches, or transported to new locations by currents. Over time, the continuous erosion can lead to the formation of sea caves, arches, and stacks along the coast.
Weathering, erosion, and deposition are the three processes that contribute to the formation of sediments. Weathering breaks down rocks into smaller pieces, erosion transports the sediments to new locations, and deposition is the settling of these sediments in new areas.
