Question

which type of energy transfer is shown in the diagram above?
a. conduction
b. convection
c. radiation
d. evaporation

Explanation:

Convection is the transfer of heat by the movement of a fluid (liquid or gas). The diagram shows the movement of air (a gas) in a cycle during day and night, which is characteristic of convection currents. Conduction is heat transfer through direct contact, radiation is heat transfer through electromagnetic waves, and evaporation is a phase - change process related to liquids turning into gases, none of which match the depicted air - movement pattern.

Answer:

B. Convection
