Geographical Winds

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 

What causes wind to blow?

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

Which term best describes how the earth's atmosphere is heated?

• Spirally
• Unevenly
• Circularly
• Kinetically

What creates the air pressure difference between the equator and the poles?

• The length of the seasons
• The shape of the earth 
• the duration of the solar year
• The amount of direct sunlight each area receives 

How are the winds in the northern hemisphere different from winds in the southern hemisphere? 

• Winds in the northern hemisphere are deflected right; winds in the southern hemisphere are deflected left
• winds in the northern hemisphere are deflected south; winds in the southern hemisphere are deflected north 
• winds in the northern hemisphere are deflected east; winds in the southern hemisphere are deflected west
• winds in the northern hemisphere are deflected left; winds in the southern hemisphere are deflected right 

if you wanted to find the jet steam, where would you go? 

• 100 km above the earth's surface 
• the area around the equator 
• 10 km above the earth's surface 
• 1 km above the earth's surface 

If you wanted to visit an area with very little wind, where might you go? 

• The doldrums around the equator
• the jet streams in the northern and southern hemisphere 
• the North or South Pole 
• the area around the Mediterranean Sea 

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 

When Earth's rotation causes the wind to curve 

• cloudy 
• Coriolis effect
• high pressure
• low pressure 

When heat rises cools then sinks 

• high pressure 
• convection current 
• low pressure 
• stratospheric pressure
