Why does Mars have the largest volcano in the Solar System?

Solar SystemMars

Quick Answer

Mars’ low gravity and lack of moving tectonic plates let lava build up in one place for a very long time. That is why Olympus Mons grew to enormous size.

The Full Story

Mars has the largest volcano in the Solar System, Olympus Mons, because lava repeatedly erupted from the same region over immense spans of time. Unlike Earth, Mars does not have active plate tectonics to move the crust and shift volcanic hotspots away. Its lower gravity also allows a mountain to grow taller before collapsing under its own weight. Olympus Mons rises about 22 km above the surrounding plains and is roughly 600 km wide.
