GEOLOGY

Detailed explanation-1: -Fossils usually form when the organisms die and get buried due to different reasons. The bodies or remains of the organisms then get covered by ashes, sand, lava, or soil to form layers over them. These layers get hardened over time due to different factors like pressure.

Detailed explanation-2: -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-3: -Fossils are formed in a number of different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. So, the soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock.

Detailed explanation-4: -Note: Fossils are formed by the process of fossilization. When a dead, decaying matter gets buried in sand, hot mud or rock, the hard parts of the body of the organism that doesn’t decompose easily, gets imprinted on the surrounding matter and turns into fossils.

Detailed explanation-5: -After death, the soft parts of an animal’s body degrade, leaving the hard parts such as the bones behind. This was buried by sediment which is made up of microscopic rock fragments. As new layers of sediment are placed on top of the skeleton, the sediment begins to solidify and convert to rock.
