As the moon moves out of Earth's shadow, the moon's surface is warmed by sunlight. Which type of heat transfer is this?
A conduction
B convection
C radiation

Explanation:  

Heat energy reaches other planets and satellites of the solar system through the process called radiation.

In this process , the heat energy travels in the form of electromagnetic waves which do not require any material medium . It is so because it is a non mechanical wave . Hence heat energy reaches earth or moon even when there is no material medium between sun and the moon . Other mode of transfer of heat requires medium like solid or liquid or gas to travel from one point to another .

the answer is a. at the equator
