• humidity

• air pressure

What does low pressure usually mean for weather?

• It will be sunny because cold air is sinking.

• It will be cloudy because cold are is sinking.

• It will be sunny because are air is sinking.

Why does a HIGH pressure system usually bring dry, clear skies?

• The air is warm, less dense, rises and moves so fast it doesn't have time to make clouds.

• The air is cold, more dense and sinks. There is no water vapor rising to make clouds.

• The air is warm, more dense and sinks. There is no water vapor rising to make clouds.

Why does a LOW pressure system usually bring cloudy and often stormy weather?

• The air is warm, less dense, rises and moves so fast it doesn't have time to make clouds.

• The air is cold, more dense and sinks. There is no water vapor rising to make clouds.

• The air is warmer and less dense. It rises and the water vapor condenses to make clouds.
