Answer:
Step-by-step explanation:
A total lunar eclipse occurs when the Earth passes directly between the Sun and the Moon, casting its shadow on the Moon. The Moon is fully illuminated by sunlight that has been bent or refracted by the Earth's atmosphere, which causes the Moon to appear reddish in color. This occurs because while the Earth's shadow covers the Moon, some of the sunlight that passes through the Earth's atmosphere is bent and redirected towards the Moon, illuminating it and giving it the reddish hue.
