Consider the diagram of the earth, sun, and moon system. which phenomenon is most directly caused by the revolution of the earth around the sun? a) the day/night cycle b) the daily tidal surges c) the phases of the moon d) the changing of the seasons

D the changes of seasons

A shouldn't be the answer as because that's caused by the earth's revolution in general

B isn't the answer as tidal surges occur because of gravity

C isn't the answer because the phases are caused by the revolution of the moon around the earth

So D. The changing of seasons is your answer by process of elimination
