Why does warm air rise?

• Warm air is more dense than cooler air.

• Warm air has more pressure than cooler air.

• Warm air is less dense than cooler air.

• Warm air has a higher dew point than cooler air.

The curving of air to the right in the Northern hemisphere is caused by ___________ and is called the _________ effect.

• Earth's rotation...Coriolis

• Earth's revolution...Coriolis

• Earth's rotation...Doppler
