What is conduction?
Conduction is the transfer of thermal energy by direct contact.
Oops!
Okay!
What is differential heating?
Differential heating is The sun's uneven heating of the Earth.
Oops!
Okay!
What are infrared rays?
A type of radiant energy that's invisible to human eyes but that we can still feel as heat.
Oops!
Okay!
Is air a fluid?
Yes! If it flows, its a fluid. Air is a fluid.
Oops!
Okay!
What is a current?
A current is a steady, predictable flow of fluid within a larger body of that fluid.

What are greenhouse gases?
Gases that can absorb infrared rays and heat up the atmosphere.
Oops!
Okay!
Where do air currents flow?
Air currents flow in the atmosphere, the layer of air surrounding the Earth.
Oops!
Okay!
What is convection?
Convection is the transfer of energy in a fluid by movement of the heated molecules.
Oops!
Okay!
