Amplify Earth Moon Sun

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.

The diagrams above show Earth and the Moon in different positions, as seen from above. Sunlight is coming from the left but Moon is dark in all of them. Could the half of the Moon that faces Earth ever be completely dark in any of these diagrams? Remember what causes a lunar eclipse!

• No, the Moon is always lit by the sun.

• Yes, the Moon is always be completely dark in Diagrams 2 and 3, but never in Diagram 1.

• Yes, the Moon is always completely dark in Diagram 1, but never in Diagrams 2 or 3.

• Yes, the Moon is always completely dark in Diagram 2 and sometimes could be dark in Diagram 3.

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’s shadow moved and was blocking less of the Moon so the astronomers were able to see more of it.

Could the half of the Moon that faces Earth ever be completely dark in any of these diagrams?

• No, the Moon is always lit by the sun.

• Yes, always in Diagrams 1 and 3, but never in Diagram 2.

• Yes, always in Diagram 3 and sometimes in Diagram 1.

• Yes, always in Diagram 3, but never in Diagrams 1 or 2.
