Answer 1

The difference between a waxing crescent and a waning gibbous is primarily their phase in the lunar cycle:

• A waxing crescent is the phase of the moon when less than half of the moon's surface is illuminated, and the illuminated part is increasing. This occurs after the new moon and before the first quarter.

• A waning gibbous is the phase when more than half of the moon's surface is illuminated, and the illuminated part is decreasing. This occurs after the full moon and before the last quarter.

In summary, the waxing crescent is increasing in illumination, while the waning gibbous is decreasing.

Answer 3

The correct response regarding the difference between a waxing crescent and a waning gibbous is:

Answer 5

The correct response regarding a similarity between the first-quarter moon and the third-quarter moon is:

The moon is located perpendicular to Earth and the sun.

In both phases, the angles formed between the Earth, the moon, and the sun are such that the moon is at a 90-degree angle to the line between the Earth and the sun. This is what gives both the first and third quarter moons their characteristic appearances.
