Which type of fossil is formed by sediments and found in sedimentary rock? mold of a fish petrified wood carbon film of a leaf preserved insect

carbon film of  a leaf preserved insect

Sedimentary rock is a rock that is formed by the compaction of sediments with the effect of heat and pressure inside the earth crust. These rocks are responsible for preserving fossils of dead animals and plants. When an organisms dies, the carcass decomposed by the decomposers present in the soil. The hard parts remains undecayed like wood, leaves, shells, bones and other skeleton remains. These remains are covered by the piles of sediments formed sedimentary rocks after compaction. A carbon film is the trace of organic matter that forms the replica of the animal or plant structure over another structure like rock. Sedimentary rock will provide a adequate pressure on the body of the organism, will result in formation of a carbon film of  a leaf preserved insect.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
