Which of the following statements describes a necessary condition for lunar or solar eclipses?

Question

Quizplus · Accepted Answer

Lunar or solar eclipses occur when the Moon intersects or passes close to the ecliptic plane, which is the apparent path of the Sun on the celestial sphere. For a lunar eclipse, this means that the Full Moon must be close to or crossing the ecliptic plane, while for a solar eclipse, the New Moon must be close to or crossing the ecliptic plane. Therefore, choice D is the correct answer as it describes a necessary condition for both types of eclipses. Choices A and B are not relevant to eclipses, as they refer to the Earth and the Sun's position relative to the celestial equator, which is not directly related to eclipses.
