Where is the atmospheric pressure the greatest?

sea level
Atmospheric pressure changes at different altitudes. Pressure is greatest at sea level and decreases with height. Air is heaviest at sea level because the air molecules are compressed by the weight of the air above them.

Where is there the greatest amount of atmospheric pressure Why?

The depth (distance from top to bottom) of the atmosphere is greatest at sea level and decreases at higher altitudes. With greater depth of the atmosphere, more air is pressing down from above. Therefore, air pressure is greatest at sea level and falls with increasing altitude.

Where does the atmospheric pressure occur in?

The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer.

Where will the atmospheric pressure be greater at ground level or at the top of high mountain?

Explanation: 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.

What is Earth’s atmospheric pressure?

atmosphere (atm) (atm) unit of measurement equal to air pressure at sea level, about 14.7 pounds per square inch. Also called standard atmospheric pressure.

Where is the atmospheric pressure the least on the ground or top of the mountain?

Pressure on Earth varies with the altitude of the surface; so air pressure on mountains is usually lower than air pressure at sea level. Pressure varies smoothly from the Earth’s surface to the top of the mesosphere.

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.

Where is atmospheric pressure useful?

Two applications of atmospheric pressure are as follows: Straw: When the liquid is sucked up by a mouth through the straw, the air pressure inside the straw and in straw decreases. And the air pressure on the surface of the liquid is equal to the atmospheric pressure.

What is the highest pressure on Earth?

1083.8mb
The highest barometric pressure ever recorded was 1083.8mb (32 in) at Agata, Siberia, Russia (alt. 262m or 862ft) on 31 December 1968.

Where will the atmospheric pressure be greater at ground level or the top of high mountain?
