## What happens to atmospheric pressure as you climb a mountain?

As altitude rises, air pressure drops. … As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. This is what meteorologists and mountaineers mean by “thin air.” Thin air exerts less pressure than air at a lower altitude.

## Why atmospheric pressure decreases as we climb a mountain?

Answer: Pressure exerted by air on any body is called atmospheric pressure. As ee climb on a mountain atmospheric pressure is decreases because the air is less dence on mountain comparison than earth surface .

## Why the temperature decreases with altitude?

As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands), and the temperature decreases. … The temperature in the troposphere — the lowest layer of the earth’s atmosphere — generally decreases with altitude.

## What kind of air has the greatest density?

Explanation: In science, it is learnt that warm air is much less dense than cold air, so as air masses are made up of air, the cold ones are denser and the warm ones are less dense. That is why during frontal rainfall, warm air rises over cool air.

## 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.

## What is the relationship between density and pressure?

Density and pressure/temperature

Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases.
