Weathering, Erosion, Deposition, Compaction, Cementation and Lithification.
There are two processes in which sedimentary rocks form. One is chemical, and the other is by deposition (sediment being deposited and then cemented together). Examples of chemical sedimentary rocks are limestone, dolomite, and rock salt.
Igneous, metamorphic, and existing sedimentary rocks can weather and erode to form sedimentary rocks. Igneous and metamorphic rocks can break down into sediments through processes like weathering and erosion, which then may accumulate and lithify into sedimentary rocks. Existing sedimentary rocks can also be reworked and lithified to form new sedimentary rocks through processes like compaction and cementation.
Sedimentary rocks.
Sedimentary rocks form at or near the Earth's surface through the accumulation and compression of sediments. These sediments can come from the weathering and erosion of pre-existing rocks, as well as from the remains of plants and animals. Over time, these sediments are compacted and cemented together to form sedimentary rocks.
Clastic sedimentary rocks form from the breakdown and erosion of larger rocks, through processes like weathering, transportation, and deposition. These sediments are then compacted and cemented together to form rocks like sandstone, shale, and conglomerates.
Sedimentary rocks are formed through three main processes: clastic, chemical, and organic. Clastic sedimentary rocks form from the accumulation and compaction of mineral and rock fragments, such as sand or clay, that are transported by wind or water. Chemical sedimentary rocks develop from the precipitation of minerals from solution, often in bodies of water, while organic sedimentary rocks are composed of accumulated plant or animal remains, such as coal or limestone. Together, these processes contribute to the diverse formations found in sedimentary rock layers.
Sedimentary rocks form when layers of rock particles are compacted or cemented together over time. Examples of sedimentary rocks include sandstone, shale, and limestone.
Compaction and cementation of sediments are the processes of lithification which form clastic sedimentary rock.
It's when parts of both igneous and metamorphic rocks are crushed together and then they form sedimentary rocks.

Sediments in sedimentary rocks are often caused by precipitation.
Sedimentary rocks are the type of rocks that can only form on or very near Earth's surface. Sedimentary rocks form from weathering processes that occur on Earth's surface.
