moon phase
observed by
student
earth
light from
the sun
which moon phase will he observe in seven days?
choose the correct answer.
new moon
3rd quarter
waxing gibbous
waxing crescent

Explanation:

The lunar cycle is approximately 28 days. Moving 7 days forward from the observed phase (assuming it's the first - quarter phase, as the diagram's position relative to Earth and Sun for the observed phase is a key indicator). In 7 days (about a quarter of the 28 - day cycle), the moon moves to the 3rd - quarter phase. The new moon is when the moon is between the Earth and the Sun. The waxing gibbous is after the first - quarter and before the full moon. The waxing crescent is before the first - quarter.

Answer:

3rd quarter
