The observed amount of difference between the perihelion of Earth in early January and aphelion in early July results in the northern hemisphere being _____.
A)cold in January and hot in July
B)hot in January and cold in July
C)equally cold in both January and July
D)equally hot in bot January and July
E)Wrong! The seasonal differences in northern hemisphere temperatures is not caused by differences in distance from the Sun.

Question

Quizplus · Accepted Answer

The seasonal differences in temperature between January and July in the northern hemisphere are primarily due to the tilt of the Earth's axis, not the distance from the Sun. During January, the northern hemisphere is tilted away from the Sun, leading to colder temperatures, while in July, it is tilted towards the Sun, resulting in warmer temperatures. The difference in Earth's distance from the Sun due to its elliptical orbit (perihelion and aphelion) has a much smaller effect on seasonal temperature changes.
