How do most fossils form? Be sure to explain your answer.
Most fossils are formed in water. So, for a fossil to form, an organism must die and fall to the bottom of a lake or ocean. Layers of sediment then cover the organism. Eventually, over millions of years, the layers of sediment become rock and preserve the shape of the organism.
