Lucia and Junior observe the Moon every night for a month. They notice that the Moon changes shapes each night. Which of the following best explains why Lucia and Junior see various Moon shapes throughout the month?

• The Sun illuminates the Moon's surface as the Moon revolves around Earth.

• The shadow of Earth falls on the Moon, causing varying shapes of the Moon.

• Earth's atmosphere gives off varying amounts of light energy throughout the month.

• The rotation of Earth around the Moon means we see it from different angles.
