The distance from Earth to the Moon is approximately 384,000 km. If the distance were to

increase to 500,000 km, which statement about the

tides would be correct?

B. The difference between high and low tide

would be much greater.

C. The difference between high and low tide

would be much less.

D. The difference between high and low tide

D. The difference between high and low tide  would not change.

Explanation:

As the moon takes an elliptical round around the earth. The distance between them varies for about 31,000 miles over a course of one month. The closer the moon is the higher will be the tides.  The sun is also responsible for the generation of the high tides on earth. Such as that on 3rd Jan. As said the distance of the moon is approx 384,000 km and will be increased to 500,000 km. This will not impact much of the rate of tidal generation.
