EES Exam Review
#3:
Semester Final Exam
Earth Science:
1. Define radiometric isotope decay.
2. What is a parent isotope?
3. What is a daughter isotope?
4. Define Half-life.
5. How do scientists determine the half-life of an object?
6. Using the below equation determine the age of a rock sample that is mostly made of Uranium that has decayed into Uranium-234. The rock sample has 12 parent isotopes and 36 daughter isotopes, it has gone through 2 half-lives, and the length of the half-life for Uranium-234 is 80,000 years.
Equation: # of half-lives x length of half-life = age of sample.
