#1. Clastic or Detrital Sedimentary Rocks The class(t)ic 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 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. Chemical Sedimentary RocksSedimentary 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.
The 3 main categories of sedimentary rocks are clastic, chemical, and organic.
They are; Mechanically formed sedimentary rock, Chemically formed sedimentary rock, and Biologically formed sedimentary rock.
organic, chemical, and clastic

there are 3 types of rocks- Igneous Rocks, Sedimentary Rocks, and Metamorphic RocksThere are three main type of rocks in the world. The names are Igneous, Sedimentary, and Metamorphic.The three main types, or classes, of rock are sedimentary, metamorphic, and igneous and the differences among them have to do with how they are formed. Sedimentary.
Sedimentary Rocks are classified based on some criterials, such as Origin and Mode of formation. Sedimentary Rocks can be classified into 3 as follows; 1. Clastic Sedimentary Rock. eg. Sandstone. 2. Organic Sedimentary Rock. eg. Limestone. 3. Chemical Sedimentary Rock. eg. Gypsum.
Igneous, metamorphic and sedimentary.
The three main groups, igneous, metamorphic and sedimentary are all part of the rock cycle. They are different in the way they formed and in their properties. Igneous rocks are formed when magma/lava cools and solidifies; metamorphic rocks are formed when a buried existing rock is heated up by the Earth's natural heat and is altered in its structure; and sedimentary rocks are formed when existing igneous or metamorphic rocks are weathered and eroded, and the resulting rock fragments are compacted together to produce a new rock. Each of these 3 types of rock can become any of the other types; ie an igneous rock can be subjected to further heating, which alters its structure, and turn into a metamorphic rock; or a sedimentary rock could be drawn back down into the Earth's molten mantle via a subduction zone, undego melting, and then later rise back to the surface and solidify to become an igneous rock.
There are three major types of rock: igneous (formed from the cooling and solidification of magma or lava) sedimentary (laid down as sediments) and metamorphic (changed by heat and/or pressure)
sedimentary
Clastic (those formed of particles of other rocks) and non-clastic (organic and chemical precipitate or evaporite rocks).

Make a list of the properties of each describing each property. In this way the similarities and differences will become more transparent. Asking others to complete your assignment or homework is self defeating.
