Mapping Mars: Geologic Sequence of Craters and River Channels

In this activity, students approach studying the surface of Mars in the same way as photogeologists. After drawing a simple features map, they will have the tools to state the general geologic history of a part of Mars' surface. They focus on the evidence showing river channels that once flowed and caused erosion. The evidence for water and volcanoes on Mars points to possible environments where life could have existed.
