Earth

Wind is caused mainly by air pressure differences that result from...

• a. uneven heating of the Earth's atmosphere.
• b. absorption of ultraviolet radiation by Earth's land masses.
• c. radiation of heat from Earth's land masses to water bodies.
• d. rotation of Earth on its axis.

Which statement correctly defines wind?

• Wind is the movement of air from areas of low pressure to areas of high pressure
• Wind is the movement of air to a colder area in the atmosphere.
• Wind is the movement of air from areas of high pressure to areas of low pressure.
• Wind is the movement of air pushed around and bouncing off Earth's surface.

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 causes global winds and convection in the atmosphere? 

• continental deflection
• the rotation of the Earth
• Moon's gravity
• unequal heating of the Earth by the sun

The Coriolis effect causes ___________.

• the Earth to rotate on its axis
• continental deflection
• global winds and surface currents to move in a curved path instead of a straight line
• global winds and deep ocean currents to move in a curved path instead of a straight line.

What impact does the Coriolis effect have upon global winds in the northern and southern hemispheres?

• Global winds blow counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.
• Global winds blow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere.
• Global winds flow clockwise in both the northern and southern hemispheres.
• The Coriolis effect has no impact upon global winds in the northern and southern hemispheres.

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 

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  

In general, how does air move?

• From areas of lower pressure to areas of higher pressure

• From areas of higher pressure to areas of lower pressure

• From areas of hot to cold

• A big fan blows it around
