Question 1982Navigation General70% to pass
Spring tides occur _______________.
AI Explanation
The correct answer is C) when the Sun, Moon, and Earth are nearly in line, in any order.
Spring tides occur when the Sun and Moon are aligned with the Earth, either on the same side (full moon) or on opposite sides (new moon). This alignment causes the gravitational forces of the Sun and Moon to combine, resulting in higher than average high tides (spring tides) and lower than average low tides. This happens regardless of the season, so it is not related to the position of the Sun over the equator as in option A.
The other options are incorrect because option B is too specific, requiring the Sun and Moon to be on the same side, and option D incorrectly states that the Sun and Moon must be at 90 degrees to each other.
