Question

Students in a science class took photographs of the Moon that were several days apart. Images that look like their photographs are shown above. The light part of the Moon appeared to get smaller over time. Why did this happen?

Answer 1

Orbit

Step-by-step explanation:

At half-way around the orbit, we can see the entire half of the Moon. This is the full moon. The Moon continues to orbit, and we start seeing less and less of the lit side.
