Question

1. what lunar phase must the moon have during a lunar and a solar eclipse?

Explanation:

A lunar eclipse occurs when Earth blocks sunlight from reaching the Moon, which only happens when Earth is between the Sun and Moon. This alignment matches the full Moon phase, when the entire face of the Moon is illuminated by the Sun as seen from Earth. A solar eclipse occurs when the Moon blocks sunlight from reaching Earth, which requires the Moon to be between the Sun and Earth. This alignment matches the new Moon phase, when the Moon is positioned between Earth and the Sun, making it nearly invisible from Earth.

Answer:

• Lunar eclipse: Full Moon phase
• Solar eclipse: New Moon phase
