Waves are generally thought of, as motion in a body of water that moves in a vertical direction.
Waves actually move in a horizontal direction, rising and falling.
Currents are created by the atmospheric winds. These currents move through water creating waves. Both of these movements that are described help create tides. Tides occur because of an attractive force called gravity that form from two massive bodies near the earth - the moon and the sun. The ocean's surface for millions of years has risen in a never-ending cycle we call the tide.
