EVERYDAY SCIENCE

Detailed explanation-1: -Organic sedimentary rocks are formed as a result of the decomposition of dead plants and animals. It contains fossils and some examples include chalk, limestone, coal, and dolomite.

Detailed explanation-2: -Organic Sedimentary Rocks Examples include fossiliferous limestone and coal. Fossiliferous limestone and coal are two examples of organically-formed sedimentary rocks.

Detailed explanation-3: -Biologic sedimentary rocks form when living organisms die, pile up, and are then compressed and cemented together. Types of biologic sedimentary rock include coal (accumulated plant material that is carbon-rich), or limestone and coquina (rocks made of marine organisms).

Detailed explanation-4: -Limestone is a sedimentary rock made almost entirely of fossils. Fossils are the remains of ancient plants and animals, like an imprint in a rock or actual bones and shells that have turned into rock. Fossils are found in sedimentary rocks and hold the clues to life on Earth long ago.

Detailed explanation-5: -Biologic Sedimentary Rocks: Biologic sedimentary rocks form when large numbers of living things die. Chert is an example for this type of rock, and this is one of the ways limestone can form. Limestone can also form by precipitating directly out of the water.
