Air Pressure and Atmosphere

Front

What is air pressure?

Back

Air pressure is the force exerted by the weight of air above a surface. It decreases with altitude.

Front

What happens to air pressure as you go higher in altitude?

Back

Air pressure decreases as altitude increases.

Front

What is the troposphere?

Back

The troposphere is the lowest layer of the atmosphere where all weather events occur.

Front

What is the relationship between air pressure and weather?

Back

Higher air pressure usually indicates cooler and drier weather, while lower air pressure can lead to stormy and wet conditions.

Front

What is altitude?

Back

Altitude is the distance above sea level.

Front

In which layer of the atmosphere do airplanes typically fly?

Back

Airplanes typically fly in the stratosphere.

Front

How does air exert pressure?

Back

Air exerts pressure in all directions: upward, downward, and sideways.

Front

What is the exosphere?

Back

The exosphere is the outermost layer of the atmosphere, where air is very thin and satellites orbit.

Front

What is the mesosphere?

Back

The mesosphere is the layer of the atmosphere above the stratosphere, where temperatures decrease with altitude.

Front

What is the significance of the ozone layer?

Back

The ozone layer, located in the stratosphere, protects the Earth from harmful ultraviolet (UV) radiation.
