#1. The classic route begins with the weathering and erosion of sedimentary, igneous, or metamorphic rocks. Through these processes, larger rock is broken up into smaller particles which are transported by moving water, ice, gravity or wind, and deposited at the bottom of a lake, a river delta, an ocean, or similar location where further movement is restricted or slowed down. The rock particles can range in size from boulders to clay particles less than .002 mm in diameter. If these rock particles are covered by additional particles, eventually the weight from above will start the process of lithification. Lithification is the compaction and cementation of particles which form rock. Compaction squeezes out the fluids and space that exist between the particles, and cementation results when the fluids that are squeezed out are replaced with minerals that were in the fluids. Once cementation occurs, the new sedimentary rock has been formed. Rocks formed in this manner include sandstone, shale, mudstone, breccia, and conglomerate and are called clastic sedimentary rocks. #2. Organic sedimentary rocks like some limestones and coal are formed largely from the remains of once living organisms. Chalk and fossiliferous limestones are formed from the skeletons of marine organisms. Coal is formed from vegetation that previously existed in swampy and marshy waterlogged soils which prevented their full decay after their death. As their remains piled up and were covered by more and more deposits, they gradually underwent compaction and cementation as described in #1. above. #3. Sedimentary rocks can also form when minerals in a body of water have so saturated the water that they precipitate out, like a cloud that is so full of moisture that it pours out rain. Some limestones are formed in this manner as the mineral calcite precipitates out of a saturated solution and undergoes the process of compaction and cementation. The supersaturated solutions can also be caused by evaporation of a body of water high in mineral content. As the water evaporates, the mineral percentage of the remaining solution becomes higher and higher, until the mineral crystallizes. Rocks such as rock salt and rock gypsum are formed in this manner. Sedimentation from precipitation and evaporation form rocks called chemical sedimentary rocks.
There are three different forms of sedimentary rock the clastic, organic sedimentary rock and chemical sedimentary rock. The above mentioned has its different process of sedimentation making it all different in the process of sedimentation or cementation.
The process of sediments being compacted and cemented to form sedimentary rocks is called lithification.
Some types of igneous and sedimentary rocks can form on Earth's surface.
Any rock type; metamorphic, sedimentary, or igneous.
All types of rock (igneous, metamorphic, and sedimentary) can be eroded and deposited to form the constituents of sedimentary rocks.
Cementing is not a process involved in the formation of sedimentary rock.

sedimentary rock is formed by the rock cycle

Mechanically formed sedimentary rock , Chemically formed sedimentary rock and Organically formed sedimentary rock.
In order to become a sedimentary rock a rock must be broken down or eroded by weathering. The sediments of the rock then go through the lithification process where they are cemented and compacted together forming a sedimentary rock.
If the original rock is eroded or broken away and then returned to sedimentary-forming conditions, it will form another sedimentary.
Igneous, metamorphic, and sedimentary.
Sedimentary rock can form another rock by being tossed and thrown into the water it takes about maybe 10 years for Sedimentary rock to form another rock.
The process by which layers of sedimentary rock are formed is called strata.
