What is the other term for the third quarter moon?
Correct Answer
A. Last quarter moon
Explanation
The other term for the third quarter moon is the last quarter moon. This phase occurs when the moon is three-quarters of the way through its orbit around the Earth. The term "last quarter" refers to the fact that this phase marks the final quarter of the lunar month before the moon transitions into the new moon phase.
2.
How does it appear in its orbit?
Correct Answer
C. Right angle
Explanation
The term "right angle" refers to a 90-degree angle. In the context of the given question, it is unclear what "it" is referring to. However, if we assume that "it" refers to an object or celestial body in its orbit, then the answer "right angle" suggests that the object appears in its orbit at a position that forms a 90-degree angle. This could imply that the object is at a specific point in its orbit where it is perpendicular to an observer's line of sight, creating a right angle.
3.
When does a third quarter moon come?
Correct Answer
C. About three weeks after new moon
Explanation
A third quarter moon comes about three weeks after a new moon because the lunar cycle is approximately 29.5 days long. A new moon occurs when the Moon is positioned between the Earth and the Sun, with the side illuminated by the Sun facing away from the Earth. As the Moon orbits the Earth, it gradually becomes more visible from Earth, reaching the third quarter phase when it is three-quarters of the way through its orbit. This typically takes about three weeks after a new moon.
4.
When does a third quarter moon set?
Correct Answer
D. Noon
Explanation
A third quarter moon sets at noon. This is because a third quarter moon rises at midnight and sets at noon, making it visible in the sky during the morning hours. As the day progresses, the moon gradually moves towards the western horizon and eventually sets at noon. This is the opposite of a third quarter moon rise, which occurs at midnight.
5.
When does it appear as a highlight?
Correct Answer
B. Dawn
Explanation
Dawn is the time when the sun rises and the sky starts to become light. It is the beginning of the day and marks the transition from night to day. During dawn, the sunlight is usually soft and gentle, creating a peaceful and serene atmosphere. Therefore, it is a common practice to highlight or emphasize the beauty and tranquility of this time of the day in various forms of art, literature, and photography.
6.
On what level does it appear in the sky?
Correct Answer
B. Highest
Explanation
The correct answer is "highest". This suggests that the object being referred to appears at the highest level in the sky. It implies that the object is positioned above other objects or is located at the topmost point in the sky.
7.
When does it rise?
Correct Answer
C. Midnight
Explanation
Midnight is the correct answer because it is the time when the sun is at its lowest point below the horizon, resulting in complete darkness. It is the middle of the night, usually around 12:00 am, and marks the transition from one day to the next.
8.
How does a third quarter moon look like?
Correct Answer
D. Half illuminated
Explanation
A third quarter moon appears as half illuminated. This means that only half of the moon's surface is visible from Earth, while the other half remains in shadow. The illuminated portion is on the left side if viewed from the northern hemisphere and on the right side if viewed from the southern hemisphere. This phase occurs when the moon is three-quarters of the way through its lunar cycle, with the sun, Earth, and moon forming a right angle.
