What is the air pressure at the top of Olympus Mons?

What is the air pressure at the top of Olympus Mons?

72 pascals
The typical atmospheric pressure at the top of Olympus Mons is 72 pascals, about 12\% of the average Martian surface pressure of 600 pascals.

How big would Olympus Mons be on Earth?

Olympus Mons is a shield volcano 624 km (374 mi) in diameter (approximately the same size as the state of Arizona), 25 km (16 mi) high, and is rimmed by a 6 km (4 mi) high scarp. A caldera 80 km (50 mi) wide is located at the summit of Olympus Mons. To compare, the largest volcano on Earth is Mauna Loa.

How does Olympus Mons compare with mountains on Earth?

Olympus Mons rises three times higher than Earth’s highest mountain, Mount Everest, whose peak is 5.5 miles above sea level. A cliff, or escarpment, surrounds the outer edge of the volcano, reaching as high as 6 miles (10 km) above the surrounding area. (The cliff alone is about as tall as Mauna Loa.)

Is Olympus Mons above the atmosphere?

Olympus Mons is so tall that it essentially sticks up out of Mars’s atmosphere. The atmosphere on Mars is thin to begin with, but at the summit of Olympus Mons, it is only 8\% of the normal martian atmospheric pressure. That is equivalent to 0.047\% of Earth’s pressure at sea level.

What kind of rock is Olympus Mons?

The surface of Mars, including Olympus Mons is basalt of a type (tholeiites) similar to that of Earth’s oceanic crust. This is the general conclusion drawn from Martian meteorites, analyses of soils and rocks at robotic landing sites, and information gathered with orbiting spacecraft.

Is Olympus Mons on Earth?

Olympus Mons on Mars, the tallest planetary mountain in the Solar System, compared to Mount Everest and Mauna Kea on Earth. The region spans 2,500 miles across the surface of Mars and contains 12 large volcanoes that are up to 100 times larger than any volcanoes on Earth.

Is Olympus Mons bigger than Mount Everest?

Olympus Mons is a shield volcano located in Mars’ western hemisphere. It is the largest volcano in the solar system at 72,000 ft tall (two and a half times the height of Mount Everest) and 374 miles wide (nearly the size of the state of Arizona).

Which of Earth’s volcanoes is most similar to Olympus Mons?

On Earth, when lava erupts from volcanoes it can be between 700 and 1,200°C. The volcanoes on Hawaii are most similar to Olympus Mons, as they have very wide bases and the slopes of the volcano aren’t very steep. Although they are a lot smaller in Hawaii, the volcanoes are very similar.
