Which has a greater influence on Earth's ocean tides, the Sun or the Moon? Why?
What will be an ideal response?
The Moon has a greater influence on Earth's tides. The gravitational force exerted by one body on another is a function of (a) the masses of the two bodies and (b) the distance between them. The Sun has a much larger mass than the Moon but it is farther away, at about 155 million kilometers from Earth. The Moon is smaller but it is only 400 thousand kilometers away from Earth. This means that the Moon exerts a stronger tidal force than does the Sun, even though the Sun has more mass.
