Question 12 12. _____ bones are more likely than _____ to be scattered, trampled, weathered, and/or crushed.

Question 13 13. In uranium-lead dating, we see that two unstable uranium isotopes decay into stable lead isotopes. Which of the following statements is true about this decay?

Question 14 14. James needs to write a report which will describe the ups and downs of mammals in a previous time period. Why would discussing epochs make sense?

Question 15 15. Which of the following types of radioactive decay does not result in a change in the number of protons and neutrons within a nucleus, but does release a lot of energy?

Question 16 16. Why do many geologists study layers of strata?

Question 17 17. Which of the following statements is true of radiocarbon dating?

Question 18 18. The change from catastrophism to uniformitarianism made scientists decide that Earth must be _____ than previously thought.

Question 19 19. 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.
