Question

Quizplus · Accepted Answer

Solar eclipses only occur at the new Moon phase when the Moon is between the Sun and Earth. However, not every new Moon results in a solar eclipse because the Moon's orbit is tilted in relation to the Earth's orbit around the Sun. This means that the Moon's shadow usually passes above or below the Earth, and only when the new Moon occurs close to one of the two points where the Moon's orbit crosses the plane of the Earth's orbit (known as the lunar nodes) can a solar eclipse occur. These events happen roughly every six months. A solar eclipse occurs when the Moon is between the Sun and Earth, blocking the Sun's light and casting a shadow on Earth. Since the Moon orbits Earth about once a month, and solar eclipses can only occur during a new Moon, they happen approximately every six months. Therefore, choice D is the correct answer.
