Q1.Where are fossils found?

In water In metals In sand In rock

1/5

Q2.Which of the following is NOT a way that fossils form?

Parts of the organism that decay get replaced by minerals The organism decays completely Some of the conditions needed for decay are missing Traces of the organism remain

2/5

Q3.How did this fossil form? (Image credit: CCO public domain - Petr Kratochvil -A shell fossil)

Parts of the organism that decay get replaced by minerals The organism decays completely Some of the conditions needed for decay are missing Traces of the organism remain

3/5

Q4.Tick TWO ways the fossil record provides evidence for evolution

Select two (2) boxes

It shows that animals have bones It shows how some species have evolved from a common ancestor It shows how species have changed over time It does not show soft-bodied organisms It is millions of years old

4/5

Q5.Tick THREE reasons why we cannot be certain of how life developed on Earth

Select three (3) boxes

Many fossils have been destroyed by geological activity Soft-bodied organisms rarely leave fossils The fossil record shows how species have changed on Earth The fossil record shows us how closely related species are Some fossils may not have been discovered yet
