Question

The positions of the moon, sun, and Earth can create the right conditions for lunar and solar eclipses to occur. Based on what you know about predicting eclipses, select all of the correct statements from the following list. During an eclipse season, an eclipse will occur no matter what the phase of the moon. Lunar eclipses must occur during every full moon. Eclipses do not occur every month because the moon is not always on the ecliptic during the necessary phases. Solar eclipses must occur during every new moon O Eclipses occur in a repeating pattern that astronomers can use to predict when they will occur D An eclipse must occur if the sun crosses a node. An eclipse must occur if the moon crosses a node.

Answer 1

An eclipse will not occur at every full or new moon due to the 5° tilt of the moon's orbit relative to the ecliptic, but only during an eclipse season when the moon's phase and orbit position align correctly.

Step-by-step explanation:

The conditions for eclipses involve the positions of the moon, sun, and Earth. To clear up the misconceptions presented in the question: During an eclipse season, eclipses may occur if the moon's phase aligns correctly with its orbit. Despite the eclipse season, there will not be an eclipse every time it's the full or new moon due to the moon's orbital tilt. Specifically, a lunar eclipse can occur only during the full moon and when the moon passes through Earth's shadow. A total solar eclipse happens when the moon is close enough to Earth to cover the sun completely and its umbra hits Earth's surface. A total solar eclipse occurs only during the new moon and not during every new moon because the moon's orbit is inclined about 5° to the ecliptic, which means it often passes above or below the sun from our viewpoint.
