1. Weathering and erosion of existing rocks: Sedimentary rocks are formed from the weathering and erosion of pre-existing rocks. This process breaks down rocks into smaller particles, which are then transported and deposited in layers.
2. Deposition by water: Sedimentary rocks can also form from the deposition of sediments carried by water. Rivers, streams, and oceans can transport sediments and deposit them in layers, which eventually become sedimentary rocks.
3. Deposition by wind: Wind can also transport sediments and deposit them in layers, forming sedimentary rocks such as sandstone and siltstone.
4. Deposition by ice: Glaciers can transport large amounts of sediments and deposit them as they melt, forming sedimentary rocks like tillite and moraine.
5. Deposition by gravity: Gravity can cause sediments to accumulate at the base of slopes or cliffs, forming sedimentary rocks such as conglomerate and breccia.
6. Organic processes: Some sedimentary rocks, such as coal and limestone, are formed from the accumulation of organic material like plant remains or shells.
7. Chemical precipitation: Some sedimentary rocks, like rock salt and gypsum, are formed from the precipitation of minerals from water. This can occur in evaporating bodies of water or in areas with high mineral content in groundwater.

- Igneous rocks: Weathering and erosion of igneous rocks can produce sediments that can be deposited and lithified to form sedimentary rocks.
- Metamorphic rocks: Weathering and erosion of metamorphic rocks can also produce sediments that can be deposited and lithified to form sedimentary rocks.
- Sedimentary rocks: Weathering and erosion of existing sedimentary rocks can produce sediments that can be deposited and lithified to form new sedimentary rocks.
- Organic matter: Decaying plants and animals can produce organic matter that can be deposited and lithified to form sedimentary rocks, such as coal and limestone.
- Chemical precipitation: Minerals can precipitate out of solution to form sedimentary rocks, such as evaporites and travertine.
