Unit 3- Winds in the Atmosphere

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 

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  

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

• Winds int he northern hemisphere are deflected right; winds int eh 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 eart; winds in the southern hemisphere are deflected west
• winds in the northern hemisphere are deflected left; einds in the southern hemisphere are deflected right 

When Earth's rotation causes the wind and water to travel in a curve. 

• cloudy 
• Coriolis effect
• high pressure
• low pressure 

Where does the initial source of energy come from that creates winds?

• the moon
• the sun
• the Earth's surface
• the rotation of the Earth

What type of winds blow constantly, predictably, and over long distances?

• land breezes
• mountain breezes
• global winds
• land breezes
