1. What is a fossil?
3
1. What is a fossil?
  • Preserved remains of a once living organism.

4
2. What is a scientist who studies fossils
called?
5
2. What is a scientist who studies fossils
called?
  • Paleontologist

6
3. How is a fossil formed?
7
3. How is a fossil formed?
  • When living things are buried by sediments and
    the sediments harden into rock and preserve the
    shapes of the organisms.

8
4. Give 3 reasons why scientists study fossils.

4. Give 3 reasons why scientists study fossils.
  • Provide evidence of how life has changed over
    time.
  • Help scientists infer how Earths surface has
    changed over time.
  • Clues to what past environments were like
  • Climate has changed over time

10
5. What type of rock could you find a fossil in?
  • Sedimentary

11
6. What does petrified mean? How does a
petrified fossil form?
12
6. What does petrified mean? How does a
petrified fossil form?
  • Petrified means turning into stone.
  • A petrified fossil forms as minerals replace all
    or part of an organism.

13
7. What is the difference between a mold and
cast fossil?
14
7. What is the difference between a mold and
cast fossil?
  • A mold is a hollow area in sediment in the shapre
    of an organism or part of an organism.
  • A cast is a copy of the shape of an organism.
  • MOLD CAST

15
8. What is a carbon film fossil?
  • An extremely thin coating of carbon on rock left
    when gases escape a buried organism

16
9. What is a trace fossil and give 2 examples.
17
9. What is a trace fossil and give 2 examples of
trace fossils.
  • Evidence of the activities of ancient organisms.
  • Ex fossilized footprint trails or burrows of
    animals

18
10. Give 3 different ways an organism can leave
behind preserved remains with little or no change.
  • Preserved in tar pits, amber, or by freezing

have gathered about past life is called

  • The fossil record

12. Give 2 reasons why the fossil record is
important.

12. Give 2 reasons why the fossil record is
important.
  • Provides evidence about the history of life
  • Shows that organisms have changed over time

have changed over time. How?
