How many tides per day result from the gravity of the Moon acting on Earth?
ATen tides
BSix tides
CNine tides
DTwo tides
Answer & Solution
Correct answer: D. Two tides
1. Ocean tides are a very observable result of the gravity of the Moon.
2. The bulge is raised on both the near side and the far side.
3. Thus there are two tides per day.
4. The actual tidal period is about 12 hours and 25 minutes.
