How does air pressure change when you go up a mountain?
Air pressure at any altitude is determined by how strongly gravity forces the surrounding air molecules together and downward. The higher the altitude the less pull gravity exerts on the air molecules, and consequently, the air pressure decreases. So, as you climb a mountain, the higher you go, the lower the ambient air pressure.
What is the relationship between altitude and air pressure to explain why rescue helicopters have a difficult time flying at altitude over 6000m.?
The higher you are from the Earth's surface - the lower the air pressure is. Helicopters are heavy machines - requiring a huge amount of effort from the rotor blades to keep it airborn. The lower the air-pressure, the harder the rotors have to work to keep the craft flying.
What happens to the air density when climbing mountains?
Density Reduces as we climb to a higher altitude
Is air pressure greater when your higher up or lower?
Air pressure is caused by the weight of all the air stacked up above you. The higher you go, the less air there is above you, so the pressure is lower.
How are the density and temperature of air related?
Higher temperature air is less dense.Less-Dense air has a higher temperature
What happen to the air pressure in a higher altitude?
The air pressure is lower the higher the altitude. That is basically how an altimeter works.
True or false the higher the altitude the lower the air pressure?
true?
What effect does the altitude of the atmosphere have on its density?
Simply put, the higher the altitude, the lower the density of the air molecules.
Is the temperature cooler in low altitude or higher altitude?
There is ever-so-slightly less... but good luck measuring that tiny difference!Altitude is the point at which an item sits in relation to sea or ground level.
How does the density of air change from lower to higher in altitudes?
The density of air decreases as altitude increases.
Why is it that when you go up a mountain you get colder because your near to the sun?
because air pressure decreases as altitude increases. As air rises, the pressure decreases. It is the lower pressure at higher altitude that causes temperature to be colder on the top of a mountain compared to sea level.
What happens to air pressure when the altitude goes up?
When the altitude increases, the air pressure decreases (or "GOES DOWN") and vice versa. This is due to the fact that air is affected by gravity, therefore there is more of it at a lower altitude than at a higher altitude.
Why does water boil at a lower temperature as altitude increases?
Air pressure affects the boiling point. Lower air pressure is present at higher altitudes.
Why is the atmospheric pressurenlower at a higher altitude than at sea level?
Beacouse of lower weight of air.
Would the air pressure in a valley be higher or lower than at sea level?
This depends on the altitude of this valley; generally is higher.
Why is a baseball hit farther at an higher altitude?
The lower air pressure allows the ball to fly easier through the air.
Why does atmospheric pressure varies from place to place?
Atmospheric pressure varies due to elevation (altitude) and because of the motion of air masses over the surface. For altitude differences, the pressure is the result of the surrounding air. Higher pressure is experienced at lower altitudes just as higher pressure is found in greater depths within a body of water. A simple explanation is that the "column of air" above a surface "pushing down" is much shorter if you move higher into the "sea of air." This lower weight is expressed as lower pressure, which represents fewer molecules within a given volume of air. The higher the altitude (eg. mountains) = The lesser the atmospheric pressure The lower the altitude (eg. sea level) = The higher the atmospheric pressure
