Earth, Moon, Sun Amplify

Suki looked up one night and saw a crescent moon. If Suki looks for the Moon again in one month, what will he see?

• Suki will see a crescent moon again, like Diagram A.

• Suki will see a quarter moon, like Diagram B.

• Suki could see either a crescent or a quarter moon; it depends on the time of year

• There’s no way to tell because the Moon’s pattern is always changing.

The diagram above shows Earth and the Moon from above (top view). Why is there a dotted circle drawn in this diagram?

• To show that the Moon is always moving around Earth in a circle.

• To show the locations of satellites that are in Earth’s atmosphere.

• To show the way that the Moon can move back and forth across Earth’s sky.

• To show the locations where the sun’s light can reach the Moon.

An artist took two photographs of the Moon that were several days apart. Images that look like his photographs are shown above. The light part of the Moon appeared to get smaller over time. Why did this happen?

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

• Between the first photograph and the second photograph, Earth’s shadow moved and was blocking more of the Moon so the artist was able to see less of it.

• Between the first photograph and the second photograph, the Moon moved so that the artist could see less of the half that faces the sun.

• Between the first photograph and the second photograph, the Moon moved farther away from the sun so less sunlight reached the Moon’s surface.

From top view, why is only half of the moon illuminated?

• There are dark rocks on the dark side of the moon.

• Light from the sun travels in straight lines, allowing light to only get to the side of the moon facing the Sun.

• None of the answer choices make sense since the entire moon is illuminated.

• As the Moon gets closer to the sun, more of it is lit by the sun.
