Question

1. If your latitude is at 45 degrees North, what will the midday sun angle be at your location on the Equinox?

a. 90 degrees

b. 45 degrees

c. 23.5 degrees

d. 71.5 degrees

2. The annual migration of the subsolar point between the 2 tropics covers how many degrees of latitude?



a. 23.5 degrees

b. 37 degrees

c. 60 degrees

d. 47 degrees

Answer 1

1) On the Equinox, the midday sun angle at 45 degrees North is 45 degrees (option b), and 2) the annual migration of the subsolar point between the two tropics covers 47 degrees (option d) of latitude.

Step-by-step explanation:

1. For the first question, on the Equinox, the midday sun angle at a latitude of 45 degrees North would be the result of 90 degrees (zenith) minus the latitude. Therefore, it is 45 degrees. This can be calculated easily as on the Equinox, the Sun is directly above the equator, which is at 0 degrees latitude; hence, the sun angle will be:90° - 45° = 45° (Option b).
2. For the second question, the subsolar point migrates between the Tropic of Cancer at 23.5° North latitude and the Tropic of Capricorn at 23.5° South latitude over the course of a year, covering a total of:23.5° N + 23.5° S = 47 degrees of latitude (Option d).
