Why is air pressures greatest at ground level?
Air pressure is greatest at ground level because the weight of the air above compresses the air molecules closer together, creating higher pressure. As altitude increases, there is less air above, resulting in lower air pressure.
Explain the concept of air pressure in terms of mass of air above some level?
Air pressure is the weight of the column of air above a specific point. As you move higher in the atmosphere, there is less air above you, so the weight pressing down decreases, causing lower air pressure. Therefore, air pressure decreases with an increase in altitude due to the reduction in the mass of air above that level.
What would you use to measure the elevation above sea level on air temperature and air pressure?
elevation above sea level . . . barometer or GPS air temperature . . . thermometer air pressure . . . barometer
How does atmospheric pressure change with height above sea level?
Atmospheric pressure is the weight of the air above the surface of the earth. As elevation increases, there is less air above the location and the pressure is lower. At sea level the column of air above the area is greater.?æ
Air pressure is greatest because there are more molecules of air pushing down from above?
Yes, air pressure is greatest at sea level because the weight of the air above is pressing down with more force. As you go higher in altitude, the number of air molecules above you decreases, causing lower air pressure.
Why is the pressure at 14000 ft above sea level 0.69 ATM while the pressure at 14000 ft below sea level is 470 ATM?
The pressure at different altitudes depends on the weight of the air column above that point. At 14000 ft above sea level, there is less air above causing lower pressure (0.69 ATM). Conversely, at 14000 ft below sea level, there is more air above causing higher pressure (470 ATM).
Which altitudes would have the lowest air pressure and why?
The highest altitudes have the lowest air pressure. Air pressure increases as altitude decreases. Above sea level is lower pressure; below sea level is higher pressure.
Where is the air pressure the greatest at sea level or ona mountaintop explain?
Air pressure is greatest at sea level because the weight of the atmosphere above compresses the air, increasing its density and pressure. As altitude increases, such as on a mountaintop, there is less air above to exert pressure, resulting in lower air pressure. Therefore, sea level has a higher concentration of air molecules and greater pressure compared to higher elevations.
Is air pressure at sea level low or high?
Air pressure at sea level is considered high because the weight of the air above exert pressure on the surface. This pressure decreases as altitude increases due to the decrease in the weight of the air column above.
Where would the air pressure be the greatest on top of a mountain or above Earth's atmosphere?
Air pressure is greatest at lower altitudes, such as at sea level, because there is more air above pushing down due to gravity. On top of a mountain, the air pressure is lower due to the reduced amount of air above. Similarly, above Earth's atmosphere, air pressure decreases significantly as altitude increases. Therefore, air pressure would be greatest at sea level, not on top of a mountain or above the atmosphere.
Why is atmospheric pressure greater at sea?
Atmospheric pressure is the weight of the air above the point... at sea level there is more air above the point then there would be at 10,000ft
What are the pressure conditions of the air above the equator?
Air pressure depends mainly on altitude - how high you are above sea level. The lattitude doesn't make much difference.
