The moon does, however, experience changes in its shape and gravity. How the moon responds to these tidal forces is, to a large degree, dependent on its internal structure. This means the tidal responses of the moon to the Earth and the sun offer clues as to what lies beneath its ...

[听力原文]Most waves are caused by winds, though earthquakes on the ocean bed can also cause them, and tides are caused by the effect of the gravity of the moon on the earth and also, although to a lesser extent, the sun’s gravity. One bulge of water is drawn upon the side of th...
