To determine the similarity between the first-quarter moon and the third-quarter moon, we can analyze the given options.
1. "The moon is always waxing in both phases." - This option is incorrect. The first-quarter moon is waxing (increasing in illumination), while the third-quarter moon is waning (decreasing in illumination).
2. "The moon is located between Earth and the sun." - This option is correct. Both the first-quarter and third-quarter moons are positioned between the Earth and the sun. In the first-quarter moon phase, the moon is on the side of Earth opposite to the sun, while in the third-quarter moon phase, the moon is on the side of Earth facing away from the sun.
3. "The moon is located perpendicular to Earth and the sun." - This option is incorrect. The moon's position during the first and third-quarter phases is not perpendicular to Earth and the sun. Instead, it forms a right angle with the Earth and the sun.
4. "The moon is always waning in both phases." - This option is incorrect. As mentioned earlier, the first-quarter moon is waxing, while the third-quarter moon is waning.
Therefore, the correct similarity between the first-quarter moon and the third-quarter moon is that both phases occur with the moon located between Earth and the sun.
