Q:

How does altitude affect temperature?

A:

Quick Answer

Air temperature decreases as altitude increases. Air is a mixture of gases, and at higher altitudes, air pressure decreases, which cools any gas. Air pressure on Earth is estimated to be about 14.7 pounds per square inch at sea level.

Full Answer

Air pressure drops to about 1.6 pounds per square inch at 50,000 feet above sea level. Air pressure is created when gravity acts on the many miles of air molecules comprising the atmosphere. Air pressure is not uniform worldwide; it can change over time. Desert regions typically have lower air pressure than other areas because the hot desert air is less dense than cool air.

  • Q:

    Why does the atmosphere become less dense as altitude increases?

    A:

    The atmosphere becomes less dense as altitude increases because there is less weight on the air molecules, making them less compressed. The air at lower altitudes is denser because it is pressed down by the weight of all the air molecules above. Also, the further away air molecules are from the Earth, the less weight they have because of a lower gravitational pull.

  • Q:

    What happens to air pressure as altitude increases?

    A:

    As altitude increases, the air pressure decreases. The surface of the earth is the bottom of an ocean of air. The layers on top increase pressure so that at sea level a body is under 14.7 pounds of pressure per square inch. Moving up in altitude decreases weight of air that causes the pressure. At 18,000 feet, the pressure decreases to 7.4 pounds of pressure per square inch.
