Question

All of the following influence the amount of solar energy that a single point on Earth receives from the sun EXCEPT:

Answer 1

I think the answer is C but unfortunately I am not 100% sure.

Answer 2

The correct answer is B. Varying speeds of Earth's rotation

Explanation:

The amount of solar energy that reaches Earth depends on multiple factors this includes the tilt or natural inclination of the Earth because this causes certain zones to be less or more exposed to sun; the time of the year because this makes the Earth be at a different distance to the sun and the location in Earth, for example, the poles are less exposed due to their location.

However, the "varying speed of Earth's rotation" is not a factor that influences the amount of solar energy Earth receives. Indeed, this speed is mainly constant as it is about 1000 per hour; also, rotation creates a pattern we perceive as day and night, which is affected the result of constant speed and the other factors previously described. This means it is false to claim rotation occurs at "varying speed" and this affects exposition to sunlight.
