Volcanoes such as the hawaiian chain that form over mantle plumes are some of the largest shield volcanoes on earth. however, several shield volcanoes on mars are gigantic compared to those on earth. what does this difference tell us about the role of plate motion in shaping the martian surface?

The difference between the size of the Hawaiin volcanoes and the gigantic Martian volcanoes tell us that the role of plate motion in shaping the Martian surface would not have been as significant as it has been on Earth.

Explanation:

The Earth's surface is substantially a result of the motion of the plates. But that doesn't appear to be the case with Mars. The huge volcanic vents are evident that there must have been tremendous lava flowing and forming most of the Martian surface.
