GEOLOGY

Detailed explanation-1: -Fossils are formed in many different ways, but most are formed when a living organism (such as a plant or animal) dies and is quickly buried by sediment (such as mud, sand or volcanic ash).

Detailed explanation-2: -Most fossils form when living things die and are buried by sediments. The sediments slowly harden into sedimentary rock and preserve the shapes of the organisms. Fossils are usually found in this type of rock.

Detailed explanation-3: -’Trace fossils’ are the evidence left by organisms in sediment, such as footprints, burrows and plant roots.

Detailed explanation-4: -Most fossils form when a dead organism is buried in sediment. Layers of sediment slowly build up. The sediment is buried and turns into sedimentary rock. The remains inside the rock also turn to rock.

Detailed explanation-5: -Mold Fossil: Forms when sediments bury an organism and the sediments change into rock; the organism decays leaving a cavity in the shape of the organism.
