No, they are not. Dolomite ( Ca,Mg(CO3)2 ) is a carbonate mineral similar to Calcite ( CaCO3 )
Chalk consists of biogenic Calcite deposited from shells and skeletons of microorganisms in water (mostly marine), and Dolomite occurs where Magnesium (Mg) has substituted Calcium (Ca) in the crystalline lattice of Calcite.
Coal on the other hand is the product of compressed organic compounds (Hydro- carbons), primarily from buried plants.
What else can I help you with?
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.
What examples of a sedimentary rock are chalk and coal?
Chalk is a type of limestone. Limestone and coal are both organic sedimentary rocks.
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.
What is an organic rock?
Organic sedimentary rock is derived mostly from the remains of organisms which have lithified into rock. Examples would be coal and chalk.
What is the difference between chalk and coal?
Chalk is a soft, sedimentary rock composed primarily of calcium carbonate, used for writing and drawing. Coal is a hard, dark, combustible rock formed from decayed plant matter, used as a fuel source. chalk is used for writing and coal is used for energy production.
What kind of rock is a sedimentary rock?
It is Limestone Gypsum Coal Dolomite Halite Sandstone Conglomerate Shale
List 2 kinds of rock that are easily weathered by carbonic acid?
Limestone Chalk Calcareous sandstone Dolomite
What is a sedimentary rock formed from materials that were once living?
A sedimentary rock formed from materials that were once living is called organic sedimentary rock. Examples include limestone, coal, and chalk, which are composed of the remains of marine organisms, plants, or other organic matter.
What is gypsum an example of?
Rock gypsum is a sedimentary rock. These rocks can be transparent or opaque. Examples could be chalk and chalk boards.
What is an example gypsum?
Rock gypsum is a sedimentary rock. These rocks can be transparent or opaque. Examples could be chalk and chalk boards.
What type of sedimentary rock is coal and chalk?
Coal is a sedimentary rock that forms from the remains of plants and organic matter, while chalk is a sedimentary rock primarily composed of the calcium carbonate remains of marine organisms like plankton and shellfish.
What are some examples of organic rock?
Examples of organic rocks include coal, which forms from compressed plant material, and limestone, which can contain fossilized remains of marine organisms like shells or coral. Another example is chalk, composed mainly of microscopic shells from plankton.
