Final answer:
Fossils are the preserved remains of organisms from the past. They are important for understanding the earth's history and how organisms have changed over time. Fossils form when organisms die and their remains are buried in sediment.
Step-by-step explanation:
What is a fossil?
A fossil is the preserved remains or traces of a living organism that lived long ago. Fossils can be bones, shells, imprints, or even preserved traces of plants or insects.
Why are fossils important for understanding the earth's history?
Fossils are important because they provide evidence about past life forms and the earth's history. They help scientists understand how organisms have changed over time and how the environment has changed.
How do fossils form?
Fossils form when organisms die and their remains are buried in sediment. Over time, the hard parts of the organism can become mineralized, turning into rock and preserving the remains.
