## 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.
