Why is mass extinction an important part of evolution?
It leads to the disappearance of all species.
It allows for the emergence of new species.
It has no impact on evolution.
It only affects plant life.
Differentiate absolute dating and relative dating in terms of the method used to age a fossil.
Absolute dating uses the position of fossils in layers of rock, while relative dating uses radioactive decay.
Absolute dating uses radioactive decay, while relative dating uses the position of fossils in layers of rock.
Both use the same method of radioactive decay.
Both use the same method of fossil position in rock layers.
Why is studying fossils important?
It helps us understand the future of technology.
It provides insights into past life forms and environments.
It is only important for finding oil.
It has no scientific value.
