In the Northern highlands of Mars, an area known as Arabia Terra, researchers have found remnants of super-volcanoes. Sci-news.com defines super-volcanoes as “a massive volcano that produces more than 1,000 cubic km of material during one eruption.”
Volcanoes have been known to be a part of the Martian landscape, most resembling mountains found in Hawaii after the layers of lava have formed a shield-like shape. The recently discovered super-volcanoes, however, have collapsed and now resemble craters rather than mountains.
It is said that this discovery can help scientists better understand the atmosphere of Mars because atmospheres consist of gases originally emitted from volcanoes.
