The process of how an organism is formed into a fossil is called

• Fossilization

• Metamorphosis

• Decompostion

• Discovery

Which step in fossilization comes first?

• An organism dies and the soft part of it decay.

• Over time, layers build pressure that turn the layers to stone.

• Wind and water erosion expose the fossil to the surface.

• Minerals around the skeleton preserve the bones.

What is the final step of fossilization?

• Minerals around the skeleton preserve the bone.

• The animal is covered of layers of dirt and sediment.

• Wind and water erosion expose the fossil to the surface.

• Over time, layers build pressure that turn the layers into stone.
