Question 1993Navigation General

The correct answer is B) They have a decreased range from normal. Apogean tides occur when the Moon is at its farthest point from the Earth. At this time, the Moon's gravitational pull on the Earth's tides is weaker, resulting in a decreased tidal range compared to normal or average tides. This is because the Moon's distance from the Earth is a key factor in determining the strength of its gravitational pull, which directly affects the size of the tidal bulges and the resulting tidal range. The other answer choices are incorrect because: A) The Moon being nearest the Earth corresponds to perigean tides, not apogean tides. C) Apogean tides can occur at any lunar phase, not just at quadrature. D) Apogean tides do not cause diurnal tides to become mixed; they simply result in a smaller tidal range.
