What are 3 requirements for an organism to become a fossil?

(a)  

• Quick Burial

• Layers of Sediments build up over the organism

• Left for a long period of time

• Animal needs to die of a disease

• Ocean water covers organism.

How are marine fossils found on the tops of mountains?

• Organism died in water and fossilized. Then continental plates collided causing uplift.

• Rivers carry fossils up to mountain tips.

• Animals pick up fossils to chew on the bones and carry them up mountains.

What is the Theory of Continental Drift?
