A few hours into your stay, the water line has managed to creep up closer and closer to your chairs and your things start to get wet! Your friend points up at the Moon and says it is to blame. What does this mean? Write a response in complete sentences. plz someone help!!!!!!!

Answers

Answer: High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. ... When you're not in one of the bulges, you experience a low tide.
