Amplify Earth Moon and Sun Review

Leticia is a space scientist who made this diagram of the Moon and Earth as seen from above (top view), with sunlight coming from the left, as shown by the arrows.

Why does Leticia’s diagram show that it’s brighter on the left half of the Moon?

• Because half of the Moon that is facing the sun is lit by the sun, and the other half is dark.

• Because the Moon has some lighter-colored rock and some darker-colored rock, and Leticia’s diagram is showing that the half of the Moon with the lighter-colored rock has rotated to the left.

• Because as the Moon gets closer to the sun more of it is lit by the sun, so Leticia’s diagram is showing sunlight on half of the Moon.

• Because there is a shadow from Earth falling on half of the Moon, and Leticia’s diagram is showing that shadow on the right half of the Moon.

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 the light part of the Moon appear to get larger over time?

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

• Between observations, the Moon moved closer to the sun so more sunlight reached the Moon’s surface.

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

• Between observations, Earth moved so its shadow 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 (top view). Sunlight is coming from the left, but these diagrams do not show what parts of Earth or the Moon are light or dark.

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 2 and 3, but never in Diagram 1.

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

• Yes, always in Diagram 2 and sometimes in Diagram 3.

Shira looked up one night and saw a full moon. How long will it be before she can see a full moon again?

• About one week.

• About one month.

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

• It could be two weeks or a month, depending on what time of year it is.

Three students made the diagrams above to show what they think the Moon looks like when it is seen from above (top view). In these diagrams, the sunlight is coming from the left, as shown by the arrows.

Which diagram is accurate and why?

• Diagram A is accurate.

• Diagram B is accurate.

• Diagram C is accurate

• All three diagrams are sometimes accurate

A student astronomer went out and took photographs of the Moon that were several days apart. Images that look like her photographs are shown above. The light part of the Moon appeared to get smaller over time.

Why did the light part of the moon appear to get smaller over time?

• Between the photographs, the Moon moved farther away from the sun so less sunlight reached the Moon’s surface.

• Between the photographs, Earth moved so its shadow was blocking more of the Moon so the student astronomer was able to see less of it.

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

• Between the photographs, the Moon moved so that the student astronomer was able to see less of the half that faces the sun.

Which of these things is true about the Moon?

• The Moon is always moving around Earth in a circle.

• The Moon is always in the same position in Earth’s sky.

• The Moon is always moving in many changing patterns/shapes around Earth.

• The Moon is always moving back and forth across Earth’s sky.

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 quarter moon, like Diagram B.

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

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

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

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

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