Why are low pressure systems often associated with bad weather?

• They bring in drier air

• They are associated with high temperatures

• They can lead to unstable, stormy conditions

• They push out cooler air

How does air pressure affect weather?

• Higher air pressure leads to stormy weather

• Lower air pressure is associated with clear skies

• Lower air pressure can lead to stormy conditions

• Air pressure has no effect on weather

How does wind try to reach equilibrium?

• By increasing the temperature difference

• By moving from colder to warmer areas

• By staying stationary

• By moving from high to low pressure areas

What effect does the Earth's rotation have on wind?

• It increases wind speed uniformly

• It decreases air pressure

• It has no effect

• It deflects the direction of winds
