Question

Air above land may be heated or cooled by what type(S) of heat transfer?

Answer 1

The answer that is correct is C because , All the light and heat energy we receive on Earth comes from the Sun, and travels through space in invisible electromagnetic waves known as radiation. Space is vast and empty, so heat energy cannot travel from the Sun by conduction or convection. Hot objects on Earth, such as fires and radiators, also radiate heat. Heat travels through solids by conduction. If one end of a metal bar is heated, heat energy moves rapidly along the bar. The hot particles do not move along the bar, but vibrate and pass energy to their neighbours. Materials that conduct electricity are also good conductors of heat. Metals conduct heat well, but wood, plastics, and glass conduct heat only poorly.

Answer 2

C. Conduction (through lighting) and Radiation (through power plants).

But I don't know for sure, always remember to double check your work.
