Venus Global Geography

This is a map of the surface of Venus (turned sideways!). As can be seen on the map, the surface of Venus consists of 2 large continents with mountain ranges, and a few large islands. There are many craters, mixed with evidence that liquid once flowed.

There is no continental drift as is seen on Earth. Nevertheless, the surface of Venus is very unusual and shows many signs of a surface which is in motion.

Compare this active surface with that of Earth, Mars, or Europa.
