Where will the atmospheric pressure greater at ground level or at the top of a high mountain?
The atmospheric pressure decreases with increasing altitude because both the height of the overlying air column and the density of the air decreases. So, the atmospheric pressure at ground level will be greater than the atmospheric pressure at the top of a high mountain.
Is air pressure greater high in the atmosphere or on the ground?
Explanation: Air pressure is caused by the weight of the atmosphere pressing down on a location. At sea level, air pressure is greatest because it is caused by the weight of the entire column of atmosphere at that altitude over that location.
Is the air pressure greater at the base of a mountain or on the top of a mountain give reason?
Less depth means less pressure. Therefore, as you go up in elevation, or height, air pressure decreases. … When air pressure is lower, as at the top of a mountain, you get less air with each breath you take. At the top of Mount Everest, Earth’s highest mountain, air pressure is one-third of what it is at sea level.
Why is air heavier closer to the ground?
The closer to the Earth’s surface, the greater the weight (or force) of the atmosphere because air near the surface has ALL air above it pushing down on it.
How do you find atmospheric pressure at high altitude?
P ( h ) = P 0 exp When , the pressure is equal to the average atmospheric sea level pressure. At a certain altitude , the pressure is twice less: P ( H ) = P 0 2 = P 0 exp
How do I calculate altitude?
Techniques to calculate density altitude
- Subtract the current altimeter setting from the standard pressure of 29.92.
- Multiply by 1,000.
- If you have a negative number, subtract it from the field elevation. Add a positive number.
