Answer:
Waning and Waxing Gibbous.
Explanation:
The different positions of the moon, as seen from Earth, reflect how much light is being reflected off the near side of the moon from the sun.
Position 1 indicates the 3rd Quarter.
Position 2 indicates the Waning Gibbous.
Position 3 indicates the Full Moon.
Position 4 indicates the Waxing Gibbous.
Position 5 indicates the 1st Quarter.
Position 6 indicates the Waxing Crescent.
Position 7 indicates the New Moon.
Position 8 indicates the Waning Crescent.
You would read the diagram counterclockwise, with positions 7 to 3 as the moon increases light and positions 3 to 7 as the moon decreases light.
The moon would be the brightest when it's at the Full Moon or close to that position. Therefore, our answer is Waning and Waxing Gibbous.
