Weather, Pressure, air masses and wind

Front

What does air temperature measure?

Back

The speed of air molecules

Front

What happens to air molecules when the temperature increases?

Back

They move faster and collide more

Front

What happens to air pressure when the temperature increases?

Back

Air pressure increases

Front

Why does a balloon or tire get tighter as the air warms up?

Back

The air molecules move faster and push harder.

Front

What happens to air pressure when the temperature decreases?

Back

Air pressure decreases

Front

What happens when air cools as it rises?

Back

It creates a low-pressure system

Front

What is a characteristic of high-pressure systems?

Back

Air cools and sinks

Front

Why does wind move from high-pressure to low-pressure areas?

Back

To balance the pressure differences

Front

Which factor causes wind to deflect in different directions?

Back

The Earth's rotation (Coriolis effect)

Front

Which wind pattern is found near the equator?

Back

Trade Winds
