Final answer:
The moon turns into a copper red color during a lunar eclipse because of sunlight passing through Earth's atmosphere and scattering blue and green wavelengths, while allowing red wavelengths to reach the moon.
Step-by-step explanation:
The moon sometimes turns into a copper red color during a lunar eclipse. This occurs because sunlight passes through Earth's atmosphere and gets scattered. The blue and green wavelengths are scattered more, while the red wavelengths are able to pass through and reach the moon, giving it a copper red appearance.
