Exploring Moon Phases: Why is only part of the Moon illuminated as it orbits around Earth, and what causes the phases we see?. ( 2pts) (2 short sentences) (use 9 year old words)

Answer 1

The Moon is only partly lit because it reflects sunlight, and we see different parts as it moves around Earth. The phases happen because the Moon changes its position, showing us more or less of the bright side depending on where it is.
