Which two considerations are used to calculate a windchill factor?

• wind speed and air temperature

• air pressure and wind direction

• wind direction and atmospheric heating

What causes differences in air pressure?

• the wind-chill factor

• the horizontal movement of air

• the unequal heating of Earth’s atmosphere

Study the image. What do the arrows indicate?

• Air moves in a direction that creates land breezes.

• Air above land warms faster than air above water.

• Air blows over long distances in a continual straight path.

What happens during a land breeze?

• Wind flows primarily during the day.

• Wind blows from poles toward the equator.

• Wind moves because air above land is cooler than air above water.
