Which one of the following statements is true about the equinoxes?
A. They occur in June and December.
B. Days and nights are equal in length everywhere.
C. The length of daylight at the Arctic and Antarctic Circles is 24 hours.
D. The Sun's vertical rays are striking either the Tropic of Cancer or the Tropic of Capricorn.
my answer is b.
Yes, it is B.
No, statement B is not true about the equinoxes. The correct answer is C. The length of daylight at the Arctic and Antarctic Circles is 24 hours during the equinoxes.
To determine which statement about the equinoxes is true, let's go through each option and understand the concept of equinoxes.
Equinoxes are the two points in the year when the Sun is directly above the Earth's equator, resulting in approximately equal lengths of day and night. There are two equinoxes during the year: the March or Vernal Equinox and the September or Autumnal Equinox.
A. They occur in June and December.
This statement is incorrect. Equinoxes do not occur in June and December. Instead, they occur around March 20-21 and September 22-23.
B. Days and nights are equal in length everywhere.
This statement is correct. During the equinoxes, the lengths of day and night are approximately equal across the globe. However, it's important to note that the exact equality of day and night may vary slightly depending on your location.
C. The length of daylight at the Arctic and Antarctic Circles is 24 hours.
This statement is incorrect. While the equinoxes do bring longer periods of daylight to the polar regions, they do not experience a full 24 hours of daylight until their respective summer solstices.
D. The Sun's vertical rays are striking either the Tropic of Cancer or the Tropic of Capricorn.
This statement is incorrect. The Sun's vertical rays strike either the Tropic of Cancer or the Tropic of Capricorn during the solstices, not the equinoxes.
Therefore, the correct statement about the equinoxes is B. Days and nights are equal in length everywhere.
