The Moon — Quiz

Question 9 • Earth and Space Science

If the Moon continues to move away at the current rate, what is a likely long-term outcome for Earth's tides?

Answer
A
Tides will disappear completely.
B
Tidal effects will weaken slightly over millions of years.
C
Tides will become more extreme due to distance.
D
Tides will remain unchanged because the Moon is still present.

Explanation

The Moon’s gravity is the main cause of Earth’s ocean tides, and its gravitational influence weakens as its distance increases. As the Moon slowly moves farther away, its contribution to tidal forces will gradually decrease, so tides are likely to weaken slightly over millions of years. They will not disappear completely because the Sun also produces tides.
