Question

Why do scientists study fossils?

a) Fossil evidence shows that changes that occurred in the past no longer occur.
b) Fossils give information about the colors and outer coverings of organisms that are no longer living.
c) Fossils give information about the time period in which organisms lived in the past.
d) Fossils help prove that organisms of the past have little relation to present-day organisms.

Answer 1

Hi,

By studying fossils, scientists can learn how life has changed over time, how earth's surface has changed and what past environments were like. Fossils form when living things die and are buried by sediment; they are usually found in Sedimentary rock. Only the hard parts of organisms generally leave fossils because the soft parts generally decay too quickly to fossilize. In case you didn't know, there are two types of fossils; rock fossils and preserved fossils.

Option c) is the correct option above.

c) Fossils give information about the time period in which organisms lived in the past.
