The water level of oceans rises and falls alternately (交替地) twice a day. This movement of water is called the tide (潮汐). Tides are caused by the pull of the sun and the moon on the earth's surface; since the moon is closer, it affects the tides more than the sun. When the moon is directly overhead, it actually pulls on the water that is below it. This causes the water level to rise11. Which of the following might be the best title for the passage?A. The Pull of the Moon and the SunB. The Moon and the TideC. The Moon and OceansD. Water Levels
