Which is the best explanation for the pattern the students observed?

• The sun lights only half of Earth, so shadow lengths are always close to the same measure.

• As the sun revolves around Earth, it shines on different areas, creating shadows.

• When the sun was low in the horizon, the shadow was long. As the sun rose, the shadow got shorter.

• Earth moved closer to the sun during its revolution, causing the shadows to get longer. As Earth moved away, the shadows got shorter.
