Wind

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 can you conclude about prevailing winds from their name? 

• They blow from west to east
• They blow all the time
• The air they contain is very warm 
• The air they contain is very cool

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

• Winds int he 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 north; 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 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 

How do jet streams influence the weather? 

• by creating clouds 
• by increasing the moisture in the atmosphere 
• by moving weather from one area to another very quickly 
• by drying out the atmosphere 

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 

What is the name for cooler air blowing from the sea to land?

• Sea Breeze
• Land Breeze
• Mountain Breeze
• None of the Above
