The image above shows the Moon orbiting the Earth through eight positions. Five of the positions are labeled. At four of the five positions, the diagram along the outside shows the Moon's phase as viewed from the Earth. Which of the diagrams shown above on the right displays the correct phase for position 4?
A.
W
B.
X
C.
Y
D.
Z
Based on the image, position 4 shows the Moon in a crescent phase. The correct diagram that displays this phase is:
C.
Y
To determine the correct phase for position 4, we need to compare the diagram along the outside with the labeled positions. Looking at position 4, we see that the Moon is located between the Earth and the Sun, with the Sun shining on the left side of the Moon as viewed from Earth.
Now let's compare this with the diagrams:
- Diagram W shows a crescent moon with the Sun shining on the right side, which does not match position 4.
- Diagram X shows a full moon, which also does not match position 4.
- Diagram Z shows a new moon, where the Sun is shining on the far side of the Moon, which again does not match position 4.
This leaves us with diagram Y as the only option left. A quick comparison shows that diagram Y correctly displays the phase for position 4, with a first quarter moon where the Sun shines on the left side of the Moon as viewed from Earth.
Therefore, the correct answer is C. Y.
To determine the correct phase for position 4, we need to understand the Moon's phases and their positions in relation to the Earth.
Moon phases are determined by the relative positions of the Moon, Earth, and Sun. As the Moon orbits the Earth, different amounts of its illuminated side are visible from the Earth, creating different phases.
Position 4 in the question refers to a specific point in the Moon's orbit. Let's examine the diagrams provided on the right:
A. W:
B. X:
C. Y:
D. Z:
To determine the correct phase for position 4, we need to match it with the correct diagram that represents that phase.
One way to find the answer is to visually compare the diagrams to determine which one matches the Moon's appearance at position 4. You can look at the shape and amount of illumination of the Moon in the diagram and try to match it to the position.
Another way to find the answer is through knowledge of the Moon's phases. Position 4 is likely to represent a specific phase, such as a crescent, gibbous, quarter, or full moon. By identifying the characteristics of the phase, we can then match it to the correct diagram.
In this case, without the images or further description, it is not possible to determine the correct phase for position 4. Therefore, the correct answer cannot be determined with the information provided.
