(D) The highest temperature on the earth is recorded around Tropic of Cancer because here Sun is directly overhead at least once during the year. In the Northern Hemisphere, the overhead Sun moves north from the equator until it reaches 23.5°North (Tropic of Cancer) for the June solstice after which it moves back south to the equator. The equator does not experience the highest temperatures on Earth. Here, rising air generates daily thunderstorms that consume considerable amounts of heat energy,suppressing the air temperature by several degrees Celsius.
