The atmospheric pressure on the moon is far less than 1.10-11 torr or mbar.
Earth: 2.5x1019 mol/cm3 (STP, 1 atm) Moon: ≈104 mol/cm3 day and ≈ 2x105 mol/cm3 night or approx. 10-14 of that found on Earth i.e. 10-14 torr.

Why is the atmospheric pressure on moon is zero?
Because the atmosphere on the moon is negligible. No atmosphere = No atmospheric pressure
The National Aeronautics and Space Administration NASA says that there is ice on some parts of the moon. What does this tell you about temperatures on these parts of the moon?
The message is that it's really cold there. As the moon has no atmosphere, there is no atmospheric pressure. Atmospheric pressure has a pronounced effect on the boiling point of water. If the water does exist on the moon and it does lie on the surface in a "no-pressure" situation, it would have to be very cold to remain there under the circumstances.
What is a sentence with the word atmospheric pressure?
Atmospheric pressure
Why did astronauts need to wear space suits when they visited the moon?
There is no atomosphere or atmospheric pressure. Without atomspheric pressure the astronauts blood would boil.
What happens to water closest to the moon?
Water on the surface of the moon will rapidly turn to water vapor as there is no atmospheric pressure on the moon. The vapor will then escape the moon's gravity which is much weaker than the gravity on Earth.
Why is the atmospheric pressure on moon is zero?
Because the atmosphere on the moon is negligible. No atmosphere = No atmospheric pressure
How high is the atmosphreic pressure on the moon?
The atmospheric pressure on the moon is nearly zero (effectively vacuum).
Is there more or less atmospheric pressure on the moon than the earth?
Less.

Would a balloon rise in the absence of atmospheric pressure?
No. On the moon they just fall. (But it sure would expand !)
What is a sentence with the word atmospheric pressure?
Atmospheric pressure
What is an atmospheric tide?
An atmospheric tide is a collective name for the pressure waves in the atmosphere similar to the tides of the ocean produced by the gravitational influence of the moon and by thermal expansion and contraction.
Why did astronauts need to wear space suits when they visited the moon?
There is no atomosphere or atmospheric pressure. Without atomspheric pressure the astronauts blood would boil.
Does rain usually occur in high atmospheric pressure or low atmospheric pressure?
rain occurs in low atmospheric pressure.
What happens to water closest to the moon?
Water on the surface of the moon will rapidly turn to water vapor as there is no atmospheric pressure on the moon. The vapor will then escape the moon's gravity which is much weaker than the gravity on Earth.
Would a balloon rise in an atmosphere where the pressure was somehow the same at all altitudes Would a balloon rise in the complete absence of atmospheric pressure such as on the surface of the moon?
No
How does the human body resist the atmospheric pressure?
because our body pressure is equal to the atmospheric pressure.
