Tania went outside and made two observations of the Moon that were several days apart. Her observations are shown above. The light part of the Moon appeared to get larger over time. Why did this happen?

• The Moon moved so that Tania was able to see more of the half that faces the sun.

• The Moon moved closer to the sun so more sunlight reached the Moon’s surface.

• The Moon rotated so that more of the light-colored rock on the Moon’s surface faced Earth.

• Earth’s shadow moved and was blocking less of the Moon so Tania was able to see more of it.
