If Earth's axis was not tilted relative to the sun (i.e. 0 degrees, instead of the actual 23.5 degrees), how would this affect latitudinal differences in incoming solar radiation?
Select one:
a. There would be latitudinal differences because incoming solar radiation would be spread across a greater area at the poles than at the equator.
b. There would be no latitudinal differences because latitude is unrelated to Earth's axis.
c. There would be no latitudinal difference because the axis of the Earth would be perpendicular to the sun.
d. There would be no latitudinal differences because all points on the Earth would be equidistant from the sun.
