Atmosphere, Air pressure, and Wind

Front

What are convection currents?

Back

Convection currents are movements of fluid (like air or water) caused by differences in temperature, where warmer, less dense fluid rises and cooler, denser fluid sinks.

Front

What happens to air pressure as you move upward into the atmosphere?

Back

Air pressure decreases as you move upward into the atmosphere.

Front

Where do you feel the wind hitting you if you are standing on the sand at the beach during the day?

Back

You feel the wind on your face.

Front

What is pressure in the context of the atmosphere?

Back

Pressure is the effect of the weight of all the air above pressing down.

Front

Where do you feel the wind hitting you if you are standing on the sand at the beach at night?

Back

You feel the wind on the back of your neck.

Front

What causes wind?

Back

Wind is caused by differences in air pressure, which result from uneven heating of the Earth's surface.

Front

What is the role of the atmosphere?

Back

The atmosphere protects life on Earth by providing oxygen, regulating temperature, and shielding from harmful solar radiation.

Front

Define air pressure.

Back

Air pressure is the force exerted by the weight of air above a given point, measured in units like pascals or millibars.

Front

What is the relationship between temperature and air pressure?

Back

As temperature increases, air pressure typically decreases because warm air is less dense than cold air.

Front

What is a sea breeze?

Back

A sea breeze is a local wind that occurs during the day when cooler air from the sea moves inland to replace rising warm air over the land.
