Quizplus · Accepted Answer

The Moon has a larger effect on the tides because its force differs more between the surface and center of the Earth due to its closer proximity. The Sun's gravitational force on the Earth is weaker because it is much farther away. However, both the Sun and Moon have an effect on the tides, with the Sun contributing about 46% towards the tides and the Moon about 54%.
