Brief Explanations:

Convection currents involve the transfer of heat through the movement of fluids (liquids or gases). A radiator emits warm air (hot fluid rising) and draws in cool air (cold fluid sinking), creating a convection - like cycle. Toasting marshmallows over a campfire is radiation (heat transfer in the form of electromagnetic waves). A pot being heated by an electric burner is conduction (heat transfer through direct contact). Feet getting hot when stepping across sand is also conduction.

Answer:

a radiator emitting warm air and drawing in cool air
