Why is Olympus Mons so big?
Olympus Mons is a Latin translation of Mount Olympus. Found in the planet Mars, Olympus Mons is known to be the tallest volcano within the Solar System. Rising twenty-five kilometers above the plains and five hundred fifty kilometers in diameters, Olympus Mons is said to be two and a half times bigger than the biggest proclaimed volcano on Earth and is said to three times taller than Mount Everest. Despite its humungous size, this volcano is deemed to be the youngest among the other volcanoes found in the Solar System. Found during the 19th century by an astronomer named Patrick Moore, Olympus Mons was observed to be asymmetrically formed with average slopes that go shallower upon reaching the base of the volcano.
Olympus Mons was described as a shield volcano. A shield volcano means a volcano came to exist due to the massive build up of lava. Same as how the state of Hawaii emerged, Olympus Mons was made up of hot molten rocks that resemble that of a warrior shield, thus giving the famous volcano a low profile and large size. Its large size has brought people, especially astronomers, in great awe. Olympus Mons grew as large as the state of Arizona primarily because the surface gravity in Mars is much lower compared to the surface gravity on Earth. This simply means there’s lesser restriction in the growth of any volcano that can be built in Mars. And the other reason is that the crusts in Mars are less active and remains to be stationary that allows lava to pile up one layer over another.
These properties in Mars make up the existence of the largest and most famous volcano in the Solar System, Olympus Mons or more simply known as, Mount Olympus.
