3
If the day were 12 hours long, what would be the approximate time interval between high and low tide?
4
Highway surfaces develop "potholes" over time. How can you use the number of potholes as an indication of the "age" of the paving? How is this like using craters to estimate the age of the Moon's surface?
5
