Due: Turn in Tables 1 and 2 before class on November 13, 2020
In this exercise, you will make rough estimates of the rate of cratering on the Earth; solarviews.com/eng/tercrate.htm is a nice reference for Terrestrial impact craters.
1. Fill in Tables 1 and 2 using the crater list found on Views of the Solar System; http://solarviews.com/eng/crater.htm (the link found on the site solarviews.com/eng/tercrate.htm above). Keep a copy of your Tables 1 and 2.
