Weather systems

What causes wind to blow?

• Differences in longitude 
• Shock waves from clouds 
• Differences in air temperature and pressure 
• The rotation of the earth

What causes warm air to rise?

• the fact that it's less dense than cold air 
• The fact that it weighs more than cold air 
• The fact that it has higher pressure than cold
• the fact that its more dense than cold air 

The reason why global winds flow from east to west and west to east, but not north to south, or south to north.

• Bernoulli's principle 
• Coriolis effect 
• high pressure 
• low pressure 

True or False:
Land heats and cools faster than water causing wind and weather.

• True
• False

Wind blows from ______ pressure areas to _____ pressure areas.

• high; low
• warm; cool
• cool; warm
• low; high

low pressure area

• warm, less dense air rises

• cool, dense air sinks

• large, circular patterns of moving air

• movement of air caused by differences in air pressure

westerlies

• winds that blow from west to east between 30 and 60 degrees latitude in both hemishpheres

• winds that blow from 30 degrees latitude almost to the equator in both hemispheres

• area around the equator where there is very little wind ("dull", "sluggish")

• area around 30 degrees latitude in both hemispheres where there is very little wind

trade winds

• winds that blow from west to east between 30 and 60 degrees latitude in both hemispheres

• winds that blow from 30 degrees latitude almost to the equator in both hemispheres

• area around the equator where there is very little wind ("dull", "sluggish")

• area around 30 degrees where there is very little wind

The Intertropical Convergence Zone is also known as...

• Prime Meridian Convergence Zone

• Equatorial Convergence Zone

• Equatorial Belt

• Equator of Low Pressure

What is the name of the belt where the tropical easterlies converge?

• Subtropical belt

• ITCZ

• Hardley

• Polar easterlies

• Westerlies
