Elements of Weather and Pressure Systems

Which measures the force of molecules pushing on a surface?

• air pressure
• temperature
• precipitation
• wind

Warm air

• sinks

• rises

• spreads

• freezes

cold air

• sinks

• rises

• spreads

• feezes

What determines the speed of the wind?

• type precipitation

• differences in air pressure

• differences in temperature

• moisture in air

Wind moves from areas of

• low pressure to areas of high pressure

• high pressure to areas of low pressure

• high humidity to areas of low humidity

• low humidity to areas of high humidity

The amount of water vapour in the air or in the lower atmosphere.

• cloud cover

• air pressure

• air temperature

• air moisture or humidity

stormy weather

• High Pressure System
• Low Pressure System

clear skies

• High Pressure
• Low Pressure

cloudy skies

• High Pressure System
• Low Pressure System
