Marble is the one that does not originate in sediments laid down by water, wind, or ice. The three most common cementing agents in a sedimentary rock are calcite, silica, and iron oxide.
Sedimentation
The combination of weathering and movement of resulting sediments of rocks is known as erosion. Weathering breaks down rocks into smaller pieces, while erosion transports these sediments to new locations through the action of water, wind, ice, or gravity.
Weathering is the process by which rocks are broken down into smaller pieces through exposure to weather conditions such as wind, water, and temperature fluctuations. These smaller pieces, known as sediments, can eventually be transported and deposited by natural forces like water or glaciers, leading to the formation of sedimentary rocks.
Sediment is small pieces of sand, soil, rocks, and other materials that settle at the bottom of a body of water. Over time, sediment can build up in layers and eventually harden into rocks or soil deposits.
Water chemically and mechanically weathers sedimentary rocks. It also weathers and erodes all rock types, transporting and depositing the sediments, a step in the formation of sedimentary rock.
Wind and water
Sedimentation
Yes, phosphate is released as rocks and sediments wear down due to weathering processes. This released phosphate can then be transported by water and incorporated into soil and bodies of water, where it becomes available for uptake by plants and other organisms.

Weathering and erosion are the processes that change rocks into sediments. Weathering breaks down rocks into smaller pieces, while erosion transports these sediments to new locations where they can accumulate. Over time, compaction and cementation turn these sediments into sedimentary rocks.
Oceanic water dissolves sediments, rocks, and salts due to its composition of various ions like sodium, chloride, magnesium, and calcium. These ions enable the water to break down minerals in the sediments and rocks, carrying them away in solution. Additionally, the continuous movement and turbulence of ocean currents help in the process of dissolving and transporting these materials.

Moving water drops sediments it is carrying when its velocity slows down. This can happen when the water enters a wider channel, encounters obstacles like rocks or vegetation, or when the gradient of the river decreases, allowing sediments to settle out of suspension.
rock cycle
When rocks settle down at the bottom of a river, the process is called sedimentation. This occurs when the water's flow slows, allowing particles and sediments, including rocks, to accumulate on the riverbed. Over time, these sediments can build up and form layers, contributing to the river's geological features.
Sediments are produced
weathering can break down rocks into sediments then erosion carries the sediments from one place to another. Last but not least deposition lies all the sediments down
