The energy from the sun is transmitted through movement of electromagnetic waves by

• conduction
• convection
• contraction
• radiation

The main reason that we have surface currents in the ocean and air is

• the sun heats the air and ocean evenly everywhere

• the heat inside the earth heats the ocean and the ocean heats the air

• the sun cannot heat both the air and water, so one must heat the other

• the sun heats air and water more at the equator because it receives more direct sunlight

Energy for convection on the Earth comes from...

• The sun
• The moon
• Solar winds
• The ocean

In convection, COOL air

• Rises
• Sinks

In convection, WARM air

• Rises
• Sinks

Heat transfers from an area of ____temperature to an area of ___ temperature.

• high to low
• low to high
• high to high
• It can travel high to low and low to high. 

Warm air is __________ dense than cold air and rises creating convection currents.

• more
• less

Near the ceiling of a room the air is warmer.  The warm air rises because of

• conduction
• convection
• radiation

During a land breeze which way does the wind blow?

• from the sea to the land
• from the land to the sea
