GEOLOGY

Detailed explanation-1: -This rock type mainly comprises coal and limestones, which are formed due to the accumulation and deposition of dead plants and animals in rock layers.

Detailed explanation-2: -Organic sedimentary rocks form from the accumulation of plant or animal debris. Examples include: chalk, coal, diatomite, some dolomites, and some limestones.

Detailed explanation-3: -Sedimentary rocks are one of three main types of rocks, along with igneous and metamorphic. They are formed on or near the Earth’s surface from the compression of ocean sediments or other processes.

Detailed explanation-4: -Organic detrital rocks form when parts of plants and animals decay in the ground, leaving behind biological material that is compressed and becomes rock. Coal is a sedimentary rock formed over millions of years from compressed plants.

Detailed explanation-5: -These types of sedimentary rocks are called “clastic rocks. “ Clastic rocks are rock fragments that are compacted and cemented together. Clastic sedimentary rocks are grouped by the size of the sediment they contain.
