You want to use radiometric dating to determine the age of a specimen. You use Isotope Z, which has a half-life of 645 years. You measure your sample and find that 1/16 of the original amount of Isotope Z is present. How old is the sample?
If the Atlantic seafloor is spreading at 2.9 cm/year and is now 6,350 km wide, how long ago (in years) were the continents in contact?
.......yr
How does that time span compare to the age of Earth? (Enter your answer as a fraction of Earth's age.)
If a tectonic plate is moving at 8.4 cm per year and a string of volcanoes appearing in the middle of the plate is 4,000 km long, how old is the oldest volcano (in millions of years)?
