Correct Answer: A
Solution :
[a] A When the moon is nearest to the earth in its orbit at perigee), its tide-producing power is greater than average, resulting in Perigean tides. These are 15-20 percent greater than average. When the moon is farthest from the earth (in apogee), the tides are called apogean tides, which are about 15-20 percent less than average. Coincidence of spring and Perigean tides results in an abnormally great tidal range, while when neap and apogean tides coincide the range is abnormally small.
