7. And yes, Mars has massive volcanoes.
Mountains filled with magma from the Earth’s mantle and occasionally spew it out in magnificent eruptions are somewhat familiar on Earth, but did you know that there are volcanoes in other parts of the solar system, as well? Scientists have found volcanoes on different moons, especially those orbiting Jupiter and Saturn, as well as on Mars.
There is so much volcanic activity on Mars that scientists have subdivided the planet into provinces based on its volcanoes. Olympus Mons is a volcano on Mars that is the largest known volcano in the entire solar system. And if you are familiar with Greek and Roman mythology, you know that Olympus Mons means Mount Olympus, where Mars, the god of war, lived.
