Question

Why are the volcanoes on Mars bigger than those on Earth?

Answer 1

HII FRIEND HERE IS YOUR ANSWER

Because the lower gravity of Mars generates less buoyancy forces on magma rising through the crust, the magma chambers that feed volcanoes on Mars are thought to be deeper and much larger than those on Earth. If a magma body on Mars is to reach close enough to the surface to erupt before solidifying, it must be big.
