Question

The most extreme northern and southern parallels to experience perpendicular rays of the Sun at local noon are located at

A) the Tropic of Cancer and the Tropic of Capricorn.
B) the Arctic Circle and the Antarctic Circle.
C) 0° latitude and 180° latitude.
D) the Equator and the Prime Meridian.

Answer 1

If Earth were tilted less, the seasons would be less extreme. The Tropic of Cancer would be at a higher latitude and the Arctic Circle would move closer to the North Pole.

Step-by-step explanation:

If Earth were tilted less, the seasons would be less extreme. The variation in day length and direct sunlight would be very small over the course of a year, and the Sun's daily path in the sky would not vary much. If Earth were tilted by 5°, the Sun's position on the day of the summer solstice would be 5° N of the celestial equator, so the Tropic of Cancer would be at the corresponding latitude on Earth of 5° N of the Equator. The Arctic Circle would be located at 90° - 5° = 85° N of the equator.
