Radiation Convection and Conduction in Atmosphere

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.

What is the definition of CONVECTION?

• When heat transfers through waves.
• When heat transfers from objects that are touching.
• movement in a gas or liquid in which the warmer parts move up and the colder parts move down
• Heat traveling from the sun

What kind of heat transfer is occurring when the sun warms the sand?

• Conduction
• Radiation
• Convection
• Density

Which of the following is an example of convection?

• A hair dryer is drying up your hair.
• When the AC or heater changes the temperature.
• When a car engine turns hot after being turned on.
• boiling spaghetti noodles in water

What heat transfer happens when you burn your finger by touching a fire?

• Radiation
• Conduction
• Convectio
• I don't know!!!!!!!!!!!

The rubber or plastic on electrical cords is an example of 

• insulators
• conductors
• radiators
• convectors

When a frying pan is touching a stove that is on, what heat transfer is happening?

• I don't know??????
• Radiation
• Conduction
• Convection

Hot air balloons rise because the heated air is less dense than cold air, so as the warm rises as the molecules spread out. The cold air is pushed downward, where it is also heated and rises. This swirling movement of  air is called...

• convection
• radiation
• insulation
• conduction

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

• conduction
• convection
• radiation
• Insolation 

The baby chickens kept warm from a heat lamps demonstrates this type of heat transfer.
