Bulge that takes place in parts of earth facing or opposite the moon

The answer would be tides, due to Earth's and the Moon's  gravitational  forces between the two planets.The  gravitational reaction causes a bulge(water)in the direction of the moon.That's why oceans, bodies of water rise at a certain time of the day, and lowers after a few hours.Without the  gravitational  pull of these two planets there wouldn't be any waves, that means people wouldm't be able to enjoy surfing.Also the water would be extreamly low, and would take some time to adapt.
