Answer 1

Microfossils

Question 2

Can be the actual remains of an organism

Answer 2

Macrofossils

Question 3

is the preserve evidence of the activity of an organism.
Example, foot imprints in mud made by walking on top or tracks made by organisms that burrow on sand or mud.

Answer 3

Trace fossils

Question 4

This happens when the remains of dead animals are buried in soil, mud, or sediment and minerals in water from the ocean, rain, or river replaced the organism’s original body structure. This mineral hardens into a fossils

Answer 4

Mineralization

Question 5

A fossil forms when a dead organism is compressed overtime and pressure drives off the organism’s liquid and gases, only the carbon outline or film of the organism remains.

Answer 5

Carbonization
