The correct answer is - True.
The polar latitudes have a solar radiation deficit, and that is because of the shape of the Earth, and because of the way the Earth rotates and revolves.
The shape of the Earth, which is ecliptic, doesn't allow the solar radiation to have the same impact on every place on the planet. On the polar latitudes, the problem with the deficiency of solar radiation is because the sun rays fall at a very sharp angle, which means that the same rays are dispersed over a much larger territory, thus the heat is not concentrated, and these parts warm up much less.
The rotation and revolving of the Earth, also goes into the favor of the Equator, but not in the favor of the poles, as the Earth is rotating in an west-east manner, and while rotating it remains its track in a way in which the Equator is the most exposed to the solar radiation, but not the poles.
