Why could there be ocean fossils found on top of a mountain?
The area used to be underwater.

What is different about relative age and absolute age?
The relative age is in comparison to another rock/fossil. The absolute age is the number of years old something is.

How do fossils form?
An animal or plant dies and is buried. It rots away, leaving a space. The space is filled with minerals.
