Obviously there is no sea, so for for Mars, the zero
elevation is defined by the mean martian radius, 3382.9 kilometers,
and the [average] atmospheric pressure [which] is 6.1 millibars.
The atmospheric pressure on Mars is about 0.6% of Earth's atmospheric pressure at sea level. It averages around 0.6 kilopascals (kPa) compared to Earth's average sea level pressure of 101.3 kPa.
Yes, it has an atmosphere so it has air pressure.
sea level
Mean sea level (MSL) which is the average level of the sea. Determinig "sea level" is a very complex measurement. All other altitude measurements in aviation, in one way or another, are referenced from the mean sea level.
how high is chipping Norton above sea level
Yes, the atmospheric pressure on Mars is about 0.6% of Earth's pressure at sea level. This is due to Mars having a much thinner atmosphere compared to Earth.
The atmospheric pressure on Mars is about 0.6% of Earth's atmospheric pressure at sea level. It averages around 0.6 kilopascals (kPa) compared to Earth's average sea level pressure of 101.3 kPa.
The surface area of Mars is 144,798,500 km2. This is about the same as all the above sea-level surface area of Earth.
The lowest point relative to "sea level" of Mars (officially measured relative to the "reference ellipsoid" for Mars) is Hellas Planitia. This huge impact crater is about 7km (4.5 miles) below the reference ellipsoid (below "sea level"). By comparison, the Challenger Depth in the Marianas Trench is the lowest point on the Earth's surface and is about 11km below sea level. (The lowest land elevation is the Dead Sea -- 422m below sea level. Water likes to fill in hole on the earth's surface!)
Your a dumb a$$ why do you need sea monkeys and why from mars
Although areas of Mars have the name "mare" (sea), there is no liquid water on the surface of Mars.
Yes, it has an atmosphere so it has air pressure.
above sea level
The lowest point in Hawaii is in the Pacific Ocean at sea level. what the heck!
Well, sea level is the standard by wich other things are measured, so zero is the answer. Sea level is sea level. Compared to what?
Yes, mean sea level (MSL) is the average (mean) height of the sea.
The pressure in Earth's atmosphere is roughly equal to that of Mars at an altitude of about 30 kilometers (18.6 miles) above sea level. This means that if you were at this altitude on Earth, you would experience a similar atmospheric pressure to that on the surface of Mars.
