Explanation / Answer
Q - The equinox
ANS – has around 12 hours of day and 12 hours of night for all locations
(An equinox is a point in the year when daytime and nighttime are exactly the same length, 12 hours each. Equinoxes occur twice a year, usually on March 20 and Sept. 22, when the Earth is tilted neither toward nor away from the sun. The word is derived from Latin: 'equi,' which comes from aequus, meaning equal, and nox-', meaning night.)
Q - The Tropic of Cancer refers to
ANS – the parallel that is the farthest northern location for the subsolar point during the year.
(The Tropic of Cancer, also referred to as the Northern Tropic, is currently 23°2613.3 (or 23.43702°) north of the Equator. It is the most northerly circle of latitude on Earth at which the Sun can be directly overhead. This occurs on the June solstice, when the Northern Hemisphere is tilted toward the Sun to its maximum extent.)
Q - Which of the following is true regarding clouds?
ANS - They act like insulation in that they have a moderating influence on temperatures.
(When the sun's energy enters the atmosphere, some of it is reflected off of clouds. This means that high cloud cover can contribute to a cooling effect: more radiation reflected means less heat present in the atmosphere.)
