A)gravitation on the small mass of water is negligibly small.

C)all parts of it are practically the same distance from the Moon.
D)they are masked by the much stronger pull of Earth gravity.
E)the tides are only observed at night.

Question

Quizplus · Accepted Answer

Tides are caused by the differential gravitational pull of the moon (and to a lesser extent, the sun) on different parts of the Earth's water bodies. In a community swimming pool, all parts of the water are at virtually the same distance from the moon, so there's no differential force to create tides.
