Astronomers made two observations of the Moon that were several days apart. Their observations are shown in the diagram above. The light part of the Moon appeared to get larger over time. Why did this happen?

• Between the first observation and the second observation, the Moon rotated so that more of the light-colored rock on the Moon’s surface faced Earth.

• Between the first observation and the second observation, the Moon moved so that the astronomers were able to see more of the half that faces the sun.

• Between the first observation and the second observation, the Moon moved closer to the sun so more sunlight reached the Moon’s surface.

• Between the first observation and the second observation, Earth moved so its shadow was blocking less of the Moon so the astronomers were able to see more of it

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

• Between the first observation and the second observation, the Moon moved so that Tania was able to see more of the half that faces the sun.

• Between the first observation and the second observation, the Moon moved closer to the sun so more sunlight reached the Moon’s surface.
