Question

Quizplus · Accepted Answer

Both the Moon and the Sun have gravitational pull on the Earth's oceans, which causes the tides. However, the Moon has a greater effect than the Sun as it is closer to the Earth. The gravitational pull of the Moon on the Earth's oceans causes two high tides and two low tides every day, while the Sun's gravitational pull causes only a small variation in the tides. Therefore, the correct choice is C: Moon and Sun.
