Be quantitative (e.g. ± 1 billion years).4) Based on your data, do you think you could tell the difference two surfaces 100 million yearsapart in age? Why or why not?5) Describe one way that you could increase the accuracy of your age determination.6) Currently the state of Washington has zero 5 km impact craters.
