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 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 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 

When heat rises cools then sinks 

• high pressure 

• convection current 

• low pressure 

• stratospheric pressure  

What is Convection?

• Convection is the transfer of energy as electromagnetic waves.

• Convection is the movement of matter due to differences in density.

• Convection is a belt of calm air and sea.

• Convection is the movement of air caused by differences in air pressure.

What is"the movement of air over short distances"?

• Westerlies

• Local Winds

• Trade Winds

• Polar Easterlies

What is temperature?

• a frequently windless area near the Equator

• a measure of the average kinetic energy of particles. The faster a particle moves, the more kinetic energy it has, the higher the temperature of the object

• A form of energy emitted by the Sun that includes, but is not limited to, visible light, ultraviolet light, and infrared energy.

• energy of motion; when particles are in motion

What are doldrums?

• circular patterns caused by the rising and sinking of air; hot (less dense) air rises; cool (more dense) air sinks

• The movement of air created by warm air rising and flowing up the slope of a mountain.

• are regions of high pressue and gentle winds at about 30 degrees north and south latitude

• a frequently windless area near the Equator
