Fossils are Formed When

Question

Fossils are formed when
A) rocks are heated by volcanic activity and then cooled rapidly.
B) rocks are heated by volcanic activity and then cooled slowly.
C) bone is mineralized by interaction with surrounding rock.
D) animals die slowly through starvation.

Accepted Answer

Fossils are formed when the mineral content of bone and other organic materials is replaced by minerals from surrounding rock through a process called mineralization. As the rock hardens around the bone or organic material, it creates a preservation of the original structure as a fossil.
