Question 30

The average distance from the Moon to Earth is about 240,000 miles. Option a (30,000) is too low, c (150,000,000) is the average distance from Earth to the Sun, and d (45,000) is incorrect. So the correct option is b.

A supermoon occurs when the Moon is at its perigee (closest point to Earth) and is full or new, but the key is it's closer than usual. Option b is opposite (apogee - micro moon), c is incorrect as it's not every full moon, d is not the cause. So the correct option is a.

A micro moon occurs when the Moon is at its apogee (farthest from Earth). Option a is supermoon, c and d are not related to distance. So the correct option is b.

Answer:

b. 240,000
