Trivia: What is the name of the solar system’s largest mountain, found on Mars?
North King
Olympus Mons
Aconcagua
Elysium Mons
Correct Answer: Olympus Mons
So why is this answer correct? : Olympus Mons is approximately 2.5 times taller than Mount Everest, and its 374-mile diameter is about the size of Arizona. The mountain is actually a shield volcano (named because it looks like a shield lying on the ground), much like the Mauna Loa volcano in Hawaii. Scientists believe Mars’ stationary crust is a major reason why Olympus Mons grew to such an enormous size.
