Sedimentary rocks are broken into two classes: clasticand chemical. Clastic sedimentary rocks are composed of rock particles, and chemical sedimentary rocks are composed of precipitation of minerals in solution.
A residue is something that is left behind after a reaction that is undesired. A precipitate is the amorphous solid formed after a reaction and is usually the desired result.
The key is the sediments. ... Biochemical sedimentary rocks are formed from organic processes that involve living organisms producing the sediments. These living organisms can be snails and clams whose discarded calcium carbonate shells can form limestone.
Finding the problem is one of the organizational processes that support problem solving. Other organizational processes that also support problem solving include formulating the problem, choosing a solution, utilizing the solution, and reviewing the outcome.
Sedimentary rocks come from the fragments of pre-existing rocks called sediments. There are three types of sedimentary rocks, each coming from different kinds of sediments. Clastic sedimentary rocks are created from the broken pieces of other rocks, while chemical sedimentary rocks form from mineral crystals like halite and gypsum

Biochemical sedimentary rocks.
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.
Non-clastic rocks
The sedimentary rock formed from minerals precipitating from a solution is called chemical sedimentary rock. It is formed through processes such as evaporation or chemical reactions, without the involvement of organic material or clastic particles.
Clastic sedimentary rock forms when fragments of preexisting rocks are compacted or cemented together. Organic sedimentary rock forms from the remains of plants or animals. Chemical sedimentary rock forms when minerals precipitate from a solution or settle from a suspension.
Chemical
Chemical rocks are sedimentary rocks that form from the precipitation of minerals in water. They are made up of minerals that have been dissolved in water and then deposited as the water evaporates or is removed. Examples of chemical rocks include limestone, gypsum, and rock salt.
Limestone is a sedimentary rock that forms as a result of chemical processes. It is composed primarily of calcite or aragonite minerals, which precipitate out of solution in bodies of water. Over time, these deposits solidify to form the limestone rock.
Chemical sedimentary rocks precipitate from solution. Organic is a subsection of chemical and includes limestone and coal, detrital, or clastic, are detritus, or fragments, of other rocks (e.g., sandstone). ChaCha on!
These minerals are called evaporites.
Sedimentary rocks can be found anywhere rock particles, clay, and organic matter has deposited itself and lithified from overburden pressure or chemical precipitation from a saturated solution. Sedimentary rock covers 75% of the surface of the Earth's continents.
