Moon phases, tides and eclipses

The cyclic rise and fall of ocean tides on Earth is primarily caused by Earth's rotation and the

• gravitational attraction of the Moon and the Sun

• direction of Earth's planetary winds

• revolution of Earth around the Sun

• temperature differences in ocean currents
