The Sun's tide-raising power is only half as great as that of the Moon. The direct pull of the Sun on the earth, however, is about `175` times that of the Moon. Why is it then that the Moon causes larger tides?

Mass effect dominates over the distance effect. We know that
`F=(GMm)/(R^(2))=MpropR^(3)`
`Hence FpropR`
Hence mass effect predominents.
