No, deposition occurs when the agents of erosion, like water, wind, or ice, drop or deposit the sediment they have been carrying. This sediment is usually dropped in a new location where the energy of the transporting agent decreases, leading to the sediment being deposited.

The final deposition of sediments usually occur in their final resting place called the deposition environment. These sediments are buried by other sediments.
Final deposition of sediment usually occurs in environments such as river deltas, deep ocean basins, or along coastlines where the energy of the transporting medium (water or wind) decreases enough for sediments to settle out and accumulate. These areas are typically characterized by low energy conditions that allow for the deposition and preservation of sediment.
It commonly occurs in bodies of water such as lakes or oceans.
Yes, sand bars are an example of deposition. They form when sediment is deposited by the movement of water, usually in rivers or along coastlines. Over time, the sediment accumulates and forms a bar of sand.
A deposition is represented by a sedimentary rock cycle diagram. It shows the process of sediments being deposited and compacted over time to form sedimentary rocks. This diagram usually includes layers of sediment accumulating to show the deposition process.
The layered look in deposition occurs because different minerals settle out of the transporting medium (usually water) at different rates, with heavier particles settling first. This results in the formation of distinct layers of sediment over time. Additionally, changes in conditions like water flow or sediment composition can also contribute to the stratified appearance of deposition.
A sandbar is typically formed through deposition. It occurs when sediment, usually sand, is deposited by ocean currents or waves, building up a ridge or bar along a shoreline or in a body of water. This deposition process helps to create new landforms and habitats along coastlines.
Varves are glacial lake deposits, usually an annual sediment of thick pale sediment denoting summer deposition when some ice melted and left silt and sand to settle in a lake, and a thin, dark layer of clay for a winter deposit when little sediment entered the lake.
Deposition from water occurs when sediment, such as sand or silt, settles out of the water and accumulates on the riverbed, lake bed, or ocean floor. This process is driven by a decrease in the energy of the water, which is usually caused by factors such as decreased flow velocity or changes in water temperature. Over time, the sediment builds up layer by layer, forming sedimentary rock.
