Question
Which of the following conditions led to fossil formation?
- When the body of a dead animal is left on the ground surface
- If the animal body does not have any hard parts
- If the bones of the animal are very light
- If the animal body is buried deep into the ground
The correct answer is: If the animal body is buried deep into the ground
During ancient times, when the remnants of animals or plants became hardened and fixed within a sedimentary rock or volcanic ash, it led to the formation of fossils. When the remnants of living organisms get saturated and hardened with minerals like calcite or silica, they get transformed into stone.
