Question

Explain three lines of evidence that indicate that the seasons in North America are not caused by the changing Earth-Sun distance as a result of Earth’s elliptical orbit around the Sun.

Answer 1

Sun is actually closest to the Earth during the winter months of North America.

During the summer months the sun rays hit directly to the surface.

During the summer months the days are longer.

Step-by-step explanation:

1. The sun is actually closest to the Earth during the winter months of North America because of the Earth's elliptical orbit. The sun is farthest from the Earth during the summer months of North America.

2. During the summer months the sun rays hit directly to the surface i.e., they sun rays are less spread out causing the Earth to heat up more. During the winter months the sun rays hitting the Earth are more spread out causing the Earth to heat up less as compared to the summer months.

3. During the summer months the days are longer, this means that North America receives more sunlight heating the Earth's surface which means that the surface cannot cool down as the nights are shorter.
