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.
Chemical sedimentary rocks form from solutions (water with something in it).
No, sedimentary rocks formed from fragments of other rocks are called clastic sedimentary rocks. Chemical sedimentary rocks form from minerals that are dissolved in water and precipitate out to form rocks like limestone or halite.
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.
Igneous and metamorphic rocks can form sedimentary rocks when they undergo weathering. As these rocks break down into smaller particles through physical and chemical processes, they can be transported and deposited, eventually lithifying into sedimentary rock. Additionally, pre-existing sedimentary rocks can also contribute to the formation of new sedimentary layers through similar weathering and erosion processes.
Chemical sedimentary rocks can form through processes such as precipitation, where dissolved minerals in water solidify and accumulate to create rock layers. Another process is evaporation, where water evaporates leaving behind concentrated minerals that eventually form into rock.

Although sedimentary rocks form in a variety of processes, the first process that would occur in the formation of the most common sedimentary rocks would be that of weathering, which is the breakdown of rocks into smaller pieces through chemical or mechanical means by nature.
A. Lava cooling. Sedimentary rocks are formed through the accumulation and cementation of sediments through physical or chemical processes, or by the build-up of plant and animal remains. Lava cooling forms igneous rocks, not sedimentary rocks.

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.
The main sub-categories of sedimentary rocks are clastic, chemical, and organic. Clastic sedimentary rocks form from the accumulation and cementation of fragments of pre-existing rocks. Chemical sedimentary rocks form from the precipitation of minerals from water solutions. Organic sedimentary rocks form from the accumulation and compression of organic materials, such as plant or animal remains.
Sedimentary rocks are formed from the accumulation of particles, which can be either clastic or chemical in nature. Clastic sedimentary rocks are composed of fragments of other rocks and minerals, while chemical sedimentary rocks form from the precipitation of minerals from solution. Both types result from processes like erosion, deposition, and lithification. Examples include sandstone (clastic) and limestone (chemical).
Some examples of chemical sedimentary rocks include limestone, dolostone, and rock salt. These rocks form when minerals precipitate out of a solution, such as when water evaporates or through processes like precipitation.
The importance of clastic versus chemical sedimentary rocks largely depends on the context in which they are analyzed. Clastic sedimentary rocks, formed from the accumulation of fragments of other rocks, are crucial for understanding geological processes and sediment transport. In contrast, chemical sedimentary rocks, which form through the precipitation of minerals from solution, are significant for studying past environmental conditions and biogeochemical cycles. Ultimately, both rock types provide valuable insights into Earth's history and processes.
