Convection and Heating the Planet

The cycle that powers the ocean currents, weather, and tectonic plates it called

• conduction current
• radiation
• condition current
• convection current

The way the heat is moving from the hot coffee is called...

• convection
• radiation
• insulation
• conduction

Warm air rises and the cool air sinks demonstrates this type of heat transfer. 

• conduction
• convection
• radiation
• Insolation 

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. 

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

• conduction
• convection
• radiation

Convection can be described as

• The process of heat sinking
• The process of heat transferring from one object to another
• The process of plants making food from the sun
• The process of heat rising

In convection, WARM air

• Rises
• Sinks

In convection, COOL air

• Rises
• Sinks

Convection currents affect the movement of plates on the Earth's crust.

• True
• False

What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.
• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• When heat transfers from objects that are touching.
• When heat transfers through the heater or AC in your house.
