What region receives the most heat from the sun?
What region receives the most heat from the sun? The equator Why do the tropics receive more insolation? Equator receives comparatively less insolation than the tropics due to presence of clouds. Generally, at the same latitude the insolation is more over the continent than over the oceans because more clouds over the oceans reflect sun […]
