Question

on june 21st in general, which latitude will receive the lowest angle of incidence?
antarctic circle
equator
north pole
south pole

Explanation:

Step1: Analyze the Earth - Sun relationship on June 21st

On June 21st (summer solstice in the Northern Hemisphere), the Sun is directly overhead at the Tropic of Cancer ($23.5^{\circ}N$). The angle of incidence of sunlight is related to the latitude - the further a location is from the subsolar point (Tropic of Cancer on this date), the lower the angle of incidence.

Step2: Compare the latitudes of the given options

• The Antarctic Circle is at $66.5^{\circ}S$.
• The Equator is at $0^{\circ}$.
• The North Pole is at $90^{\circ}N$.
• The South Pole is at $90^{\circ}S$.

The South Pole is the furthest from the subsolar point (Tropic of Cancer) among the given options.

Answer:

South Pole
