How does atmospheric pressure affect weather? MET Office

What is atmospheric pressure?

• The force exerted by the weight of water above us

• The force exerted by the weight of rocks above us

• The force exerted by the weight of air above us

• The force exerted by the weight of plants above us

Where is pressure highest?

• In underground caves

• In valleys

• At sea level

• At the top of mountains

What happens when air rises?

• No pressure is created

• High pressure is created

• The pressure remains the same

• Low pressure is created

What happens when air sinks?

• High pressure is created

• The pressure remains the same

• No pressure is created

• Low pressure is created

What does air naturally want to do in terms of pressure?

• Disperse in all directions

• Remain stagnant

• Flow from high pressure to low pressure

• Flow from low pressure to high pressure

What weather conditions are associated with high pressure?

• Snowy and foggy

• Calm, clear or sunny

• Windy and cloudy

• Stormy and rainy

What weather conditions are associated with low pressure?

• Windy and cloudy

• Snowy and foggy

• Stormy and rainy

• Calm, clear or sunny

What are storms?

• Areas of high pressure

• Areas of no pressure

• Areas of moderate pressure

• Areas of low pressure
