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

Atmospheric pressure is lower at the poles compared to the equator because of the Earth's shape and rotation. The polar regions receive less direct sunlight, causing the air to be cooler and denser. This creates high-pressure systems that lead to lower atmospheric pressure.

A pressure reading less than atmospheric pressure is?
Low pressure
What will happen to the atmospheric pressure as the altitude increases?
As altitude increases, atmospheric pressure decreases. This is because there is less air above the point at higher altitudes, resulting in lower pressure.
Why does atmospheric pressure increase with height?
Atmospheric pressure decreases with height due to the weight of the air above pushing down on the air below. As you move higher in the atmosphere, the air becomes less dense because there is less weight of air above it, leading to a decrease in pressure.
The air above the poles is?
colder than at the equator due to the angle of sunlight hitting the poles, causing denser air to sink and accumulate. This results in high atmospheric pressure and lower temperatures.
What are Pressures less then 0 KPa are called?
Pressures less than 0 kPa are called negative pressures. They indicate a pressure lower than atmospheric pressure.
A pressure reading less than atmospheric pressure is?
Low pressure
Is there more or less atmospheric pressure on the moon than the earth?
Less.
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.
What will happen to the atmospheric pressure as the altitude increases?
As altitude increases, atmospheric pressure decreases. This is because there is less air above the point at higher altitudes, resulting in lower 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
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 decreases with increasing altitude because there is less air above pushing down on the air at higher altitudes. Mount Everest is much higher in altitude compared to places on Earth where the pressure is measured at 14.7 psi. As you go higher up, the weight of the air above becomes less, leading to lower atmospheric pressure.
Does rain usually occur in high atmospheric pressure or low atmospheric pressure?
Rain typically occurs in low atmospheric pressure systems where air rises, cools, and condenses to form clouds and precipitation. High atmospheric pressure systems typically bring stable and clear weather conditions with less likelihood of rain.
Can mean effective pressure less than atmospheric pressure?
Yes, mean effective pressure can be less than atmospheric pressure in certain scenarios, such as during the intake stroke of an internal combustion engine when the piston moves downward and creates a negative pressure in the cylinder. This can occur when there is a pressure drop due to factors like engine design, intake system restrictions, or operating conditions.
Why does atmospheric pressure increase with height?
Atmospheric pressure decreases with height due to the weight of the air above pushing down on the air below. As you move higher in the atmosphere, the air becomes less dense because there is less weight of air above it, leading to a decrease in pressure.
How does atmospheric pressure change as you move up away from sea level?
Atmospheric pressure decreases as you move up away from sea level because there is less air above pushing down on you. For every 100 meters increase in altitude, atmospheric pressure typically drops by about 12%.
