Crater Maker lets students think like planetary geologists.

Students will explore the following paradox: we see craters on the Moon, Mars, and Mercury, but it is very hard to find craters on Earth. Why does Earth lack impact craters?

They will work in teams to examine surface maps of Earth and one other planetary body: Mercury, Venus, Earth, the Moon, Mars, and the moons Io, Ganymede, Europa, and Titan. They will have data on size, temperature, atmosphere, volcanic activity, weather and oceans.

They will discover that crater size and distribution is a very useful way of determining the age of a planetary surface, and that the lack of craters indicates a very young surface, with weathering playing a large role in erasing impact craters, but also volcanism.
