Question

which of the following best describes why we see the moon at different phases? (1 point)
we are only seeing portions of the moon that is blocking sunlight.
we are only seeing portions of the moon that is reflecting sunlight.
we are only seeing portions of the moon when its orbit is closest to the earth.
we are only seeing portions of the moon that is reflecting earths atmosphere.

Explanation:

1. Analyze the first option: The moon does not block sunlight to be seen; it reflects it, so this is incorrect.
2. Analyze the second option: The moon's phases occur because as it orbits Earth, different portions of its sun - reflecting surface are visible from Earth. This matches the scientific explanation of lunar phases.
3. Analyze the third option: The moon's orbital distance (perigee) is not related to the phases; phases are about the angle of sunlight reflection, so this is incorrect.
4. Analyze the fourth option: The moon does not reflect Earth's atmosphere to be seen; it reflects sunlight, so this is incorrect.

Answer:

B. We are only seeing portions of the moon that is reflecting sunlight.
