The earth is slightly flattened at the poles. This has the effect of lowering the surface and raising the weight of air above.

A pressure reading less than atmospheric pressure is?
Low pressure
Has Mars got an atomsophere?
Mars has a very thin atmosphere made up mostly of carbon dioxide. The atmospheric pressure on Mars is less than 1% of the atmospheric pressure on earth.
What is low atmospheric pressure?
Atmospheric pressure is caused by the weight of the air in the earths atmosphere that is above you. At sea level this pressure is said to be 1 bar or one atmosphere. Now, as you go up a mountain there is less air above you and thus the atmospheric pressure is less and the pressure you experience because of your altitude is said to be your local atmospheric pressure. However, the earths atmosphere is heated by the sun and moves in eddies to the poles where it is cooled and flows back to the equator - this is called the weather. When you have hot air above you it is less heavy than cold air so, as the atmosphere blows over you, the pressure of the air changes and you can work out if the air above you is hot or cold by comparing the measure you measure against your local atmospheric pressure.
Air pressure near the equator is less than air pressure at the poles a fact that causes air to move where?
From west to east
What is Neptune's atmospheric pressure compared to earth's atmospheric pressure?
42% higher
A pressure reading less than atmospheric pressure is?
Low pressure
Can mean effective pressure less than atmospheric pressure?
no Because any body subject is affected by the atmospheric pressure in the case of its occurrence under the pressure of what it means that the pressure for increased atmospheric pressure.
Why does Mars have low atmospheric pressure?
Mars has a low atmospheric pressure reading because there is a lighter atmosphere, which means less air, which means less weight or pressure.
Is there more or less atmospheric pressure on the moon than the earth?
Less.
Is pressure in a balloon less than atmospheric pressure?
No, the pressure of the balloon is more than the atmospheric pressure because the gasses in the balloon are compressed by the stretched material.
Which is true about intrapulmonary pressure and intrapleural pressure?
Intrapulmonary pressure will equalize to atmospheric pressure during a breathing cycle, but intrapleural pressure should always be less than atmospheric pressure.
How much negative pressure is possible to create?
less than the atmospheric pressure
Will a yo yo work differently at the poles compared to the equator?
Yes, because of differ atmospheric pressure.
Why is the atmospheric pressure at the top of mt Everest 5 lbin squared much less than the atmospheric pressure here on earth 14.7 lbin squared?
The atmospheric pressure is caused by the weight of the air on top of us. At the top of mount Everest, there is less air above the exhausted climber (because a lot of the air is below). Less air, less weight, less pressure.
What do you consider as low pressure in thermodynamics?
Significantly less that atmospheric pressure, which is 101,300 Pa.
What happens with altitude relative to pessure?
as altitude rises less there is less atmospheric pressure
Does temperature change atmospheric pressure?
Yes, the hotter it is the more pressure, and therefore the colder the less pressure. Ther you go :)
