The moon’s gravity.

The Moon’s gravitational pull (together with the Sun’s) creates the tidal forces that produce the two bulges of water on opposite sides of Earth. Wind and the Coriolis effect affect ocean currents and local sea level, and Earth's rotation causes an equatorial bulge, but the global tidal bulges are due to the Moon's gravity.
