Coal is a sedimentary rock. However, harder forms of coal, because of exposure to elevated temperature and pressure, are metamorphic rock.
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.
The material comprising the rocks coal and limestone are derived from organisms. Therefore, they are classified as organic sedimentary rocks.
it can be sedimentary rocks
Coal and chalk.
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.
Chalk is a type of limestone. Limestone and coal are both organic sedimentary rocks.

Coal and Sandstone are two types of sedimentary rocks.
Granite, shale, coal, and limestone are commonly known as types of rocks. Granite is an igneous rock, shale is a sedimentary rock, coal is a sedimentary rock that forms from organic matter, and limestone is a sedimentary rock composed mainly of calcite.
No. For example, coal is a black sedimentary rock.
Fossils rocks are sedimentary rocks such as coal, limestone, sandstone, and shale.
Examples of organic sedimentary rocks include coal, which forms from the accumulation and compaction of plant remains, and limestone, which can contain organic debris such as shells and coral. Organic sedimentary rocks are derived from the remains of living organisms.
