Martian lava tubes are volcanic caverns on Mars that are believed to form as a result of fast-moving, basaltic lava flows associated with shield volcanism. [1] Lava tubes usually form when the external surface of the lava channels cools more quickly and forms a hardened crust over subsurface lava flows. [2]
Arsia Mons is a shield volcano with a relatively low slope and a massive caldera at its summit. The southernmost of the three Tharsis Montes volcanoes, it is the only major Tharsis volcano south of the equator. [2] Topographic map of Arsia Mons. The volcano is 435 kilometres (270 mi) in diameter, almost 20 kilometres (12 mi) high (more than 9 ...
Olympus Mons (/ əˌlɪmpəs ˈmɒnz, oʊ -/; [4] Latin for ' Mount Olympus ') is a large shield volcano on Mars. It is over 21.9 km (13.6 mi; 72,000 ft) high as measured by the Mars Orbiter Laser Altimeter (MOLA), [5] about 2.5 times the elevation of Mount Everest above sea level. It is Mars's tallest volcano, its tallest planetary mountain ...
Valles Marineris (/ ˈvælɪs mærɪˈnɛərɪs /; [1] Latin for Mariner Valleys, named after the Mariner 9 Mars orbiter of 1971–72 which discovered it) is a system of canyons that runs along the Martian surface east of the Tharsis region. [2] At more than 4,000 km (2,500 mi) long, 200 km (120 mi) wide and up to 7 km (23,000 ft) deep, [3][4 ...
The NASA Perseverance rover may have found a pivotal clue that’s central to its mission on Mars: geological evidence that could suggest life existed on the red planet billions of years ago. The ...
Elysium Mons / ɪ ˈ l ɪ z i ə m ˈ m ɒ n z / is a volcano on Mars located in the volcanic province Elysium, at , in the Martian eastern hemisphereIt stands about 12.6 km (41,000 ft) above its base, [2] and about 14.1 km (46,000 ft) above the Martian datum, [2] making it the third tallest Martian mountain in terms of relief and the fourth highest in elevation.

Volcanism is a process in which magma from a planet's interior rises through the crust and erupts on the surface. The erupted materials consist of molten rock (lava), hot fragmental debris (tephra or ash), and gases. Volcanism is a principal way that planets release their internal heat. Volcanic eruptions produce distinctive landforms, rock ...
