Question 6 6. Why do many geologists study layers of strata?

Question 7 7. If two dinosaurs, one small and one large, both die in similar conditions and are both rapidly buried in the same material, which is more likely to be preserved as a fossil?

Question 8 8. Which of the following is the term used for the process by which an unstable atomic nucleus loses energy by releasing radiation?

Question 9 9. If a parent nucleus is feeling unstable because the ratio of neutrons to protons is too great, it might undergo a type of radioactive decay which results in the neutron emitting an electron (a beta particle) from the nucleus and turning into a proton.
