How are fossils created?
A
Traces of organisms get turned into stone.
B
Dead organisms are quickly buried for millions of years.
C
Animals get trapped.
D
All of the above
Explanation: 

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: -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-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: -Several different physical and chemical processes create fossils, according to the New York State Geological Survey. Freezing, drying and encasement, such as in tar or resin, can create whole-body fossils that preserve bodily tissues.
