What's waxing crescent moon?
Correct Answer
A. A crescent moon that's always seen after sunset
Explanation
A waxing crescent moon refers to a slim crescent that appears after sunset. This phase occurs when less than half of the moon is illuminated, and the illuminated portion is increasing. The crescent shape is formed by the shadow of the Earth partially covering the moon, with the lit portion visible. It is always seen after sunset because the moon rises in the east as the sun sets in the west, allowing for the crescent to be visible in the evening sky.
2.
What's this moon usually called?
Correct Answer
A. Young moon
Explanation
The moon is usually called a "young moon" when it is in its early stages of the lunar cycle and appears as a thin crescent. This phase occurs just after the new moon phase, when the moon is barely visible in the sky. As the lunar cycle progresses, the moon gradually becomes more illuminated and transitions into the "full moon" phase. The term "young moon" is used to describe the moon's appearance rather than its age.
3.
At this phase Earth, moon and sun are...?
Correct Answer
B. Nearly on the same line
Explanation
At this phase, Earth, moon, and sun being "nearly on the same line" means that they are in a configuration where they are almost aligned in a straight line. This alignment occurs during a specific phase of the moon, known as the "new moon" phase. During this phase, the moon is positioned between the Earth and the sun, causing the illuminated side of the moon to face away from the Earth, making it appear as if there is no moon visible from Earth. The alignment of the Earth, moon, and sun being nearly on the same line is what causes this phenomenon.
4.
Is crescent moon Earth's shadow on the moon?
Correct Answer
C. No
Explanation
The crescent moon is not Earth's shadow on the moon. The shape of the crescent moon is caused by the angle at which the sunlight hits the moon's surface. When the moon is in its crescent phase, the sunlight is only illuminating a small portion of the moon, creating the crescent shape. Earth's shadow on the moon occurs during a lunar eclipse when the Earth blocks the sunlight from reaching the moon, causing it to appear dark or reddish.
5.
If there's a shadow on the moon, whose is it?
Correct Answer
B. Moon's
Explanation
The shadow on the moon would be the moon's own shadow. This is because the moon does not emit light of its own, but instead reflects light from the sun. When an object blocks the sunlight from reaching the moon, it creates a shadow on the moon's surface. Therefore, the shadow on the moon belongs to the moon itself.
6.
The illuminated side of the moon is facing...?
Correct Answer
A. Mostly away from us
Explanation
The illuminated side of the moon is facing mostly away from us because the moon orbits around the Earth, and we only see the portion of the moon that is reflecting sunlight. As the moon orbits, the angle at which the sunlight hits the moon changes, causing different portions of the moon to be illuminated. When the illuminated side is mostly away from us, we see a crescent or a new moon.
7.
Waxing moon means the moon is getting...?
Correct Answer
A. Larger
Explanation
The correct answer is larger because waxing moon refers to the phase of the moon when it appears to be getting bigger. During this phase, the illuminated portion of the moon increases, leading to a larger visible surface area.
8.
This period lasts about...?
Correct Answer
C. 14 days
Explanation
The correct answer is 14 days. This is the average length of a menstrual cycle, which is the time from the first day of one period to the first day of the next period. It is important for women to track the length of their menstrual cycle in order to better understand their reproductive health and fertility.
