Is chalk clastic or non clastic?
Chalk is non-clastic, as it is primarily composed of the mineral calcite (calcium carbonate) formed from the remains of microscopic marine organisms such as plankton. These organisms contribute to the fine-grained texture of chalk through chemical precipitation rather than mechanical weathering or erosion.
How do you classify sedimentary rocks?
The basic division of sedimentary rocks is into clastic and chemical rocks. Clastic rocks are formed when grains form a sediment and are then cemented together, as happens with sandstone or shale. Chemical rocks form when solid precipitates out of solution, for instance when calcium carbonate is formed from sea water to give chalk.
What type of sedimentary rock is chalk clastic chemical or biochemical?
Chalk is a biochemical sedimentary rock, formed mainly from the calcareous remains of microscopic marine organisms like plankton. It is primarily composed of calcium carbonate and is often found in extensive deposits in areas that were once covered by ancient seas.
Chalk and coal are examples of a kind of sedimentary rock that is called?
Chalk and coal are examples of biochemical sedimentary rocks. Biochemical sedimentary rocks are formed from the accumulation and compression of organic remains such as shells, coral, or plant material.
Chalk and coal are examples of a kind of sedimentary rock called?
Chalk and coal are examples of a kind of sedimentary rock called biochemical sedimentary rock. Biochemical sedimentary rocks form from the accumulation and lithification of organic remains, such as shells and plant material.
Is chalk clastic chemical or organic?
It is clastic
What are the subtypes of sedimentary rocks?
Chemical: Minerals were dissolved in water to form it. Organic: Formed from the remains of living things. Clastic: Formed form bits of other rocks.
What are the types of sedimentary rocks?
Clastic and nonclastic

How are clastic sedimentary rocks divided?
Clastic (or detrital): Sedimentary rock formed from particles of other sedimentary, metamorphic, or igneous rock which has been weathered, eroded, deposited, compacted and cemented. Examples of clastic sedimentary rock include shale, sandstone, mudstone, and conglomerate.Chemical: Chemical sedimentary rocks have intergrown mineral crystals that are precipitated from saturated aqueous solutions and chemical residues. The precipitated minerals that are commonly included are halite, quartz, limonite, calcite, chert, dolomite, hematite, and gypsum; consequently, common chemical rocks are limestone, chert, and rock gypsum.Organic:Organic sedimentary rock is rock that is derived or generated from sediments that are produced by organisms. Coal and chalk are examples of organic sedimentary rock.

What is an example of a sedimentary rock that is biochemical (organic)?
Limestone and chalk are formed from organic material Limestone - Clastic shell fragments Chalk - Microscopic shells of calicum carbonate plates formed by single celled algaes Chert - Microscopic siliceous organisms, recrystallized silica
What are three types of sedimentary rocks?
Clastic, chemical, and Organic
What are some organic sedimentary rocks?
Coal and chalk.
What examples of a sedimentary rock are chalk and coal?
Chalk is a type of limestone. Limestone and coal are both organic sedimentary rocks.
