Why is the northern hemisphere experiencing longer days compared to the southern hemisphere in this diagram?
A.)The northern hemisphere is tilted away from the Sun and is thus rotating in the sunlit part of the Earth for a longer period of time compared to the southern hemisphere.
B.)The northern hemisphere is tilted toward the Sun and is thus rotating in the sunlit part of the Earth for a longer period of time compared to the southern hemisphere.
C.)The northern hemisphere is tilted toward the Sun and is thus rotating in the sunlit part of the Earth for a shorter period of time compared to the southern hemisphere.
D.)The northern hemisphere is tilted away from the Sun and is thus rotating in the sunlit part of the Earth for a shorter period of time compared to the southern hemisphere.
