Question

Quizplus · Accepted Answer

Tidal bulges are the result of the gravitational force between two bodies. In this case, the gravitational force between the Earth and Moon would create two tidal bulges on the Moon if it were covered in water. One tidal bulge would be facing directly towards the Earth (the sub-lunar point) and another would be directly opposite (the anti-lunar point). These two tidal bulges would create high tides and low tides on the Moon, just as Earth's tidal bulges create ocean tides. Therefore, the best choice is B)2 tidal bulges.
