How are waves different from tides?

Waves are caused by wind, while tides are the regular rise and fall of the ocean’s surface caused by the gravitational pull of the Sun and the Moon on the water that is in the ocean. Waves are formed when winds blow over the surface of the ocean. Stronger winds create larger waves. The water in a wave normally moves in circles. As a wave approaches the land it is slowed down by the rising slope of the seabed. But it is the bottom portion of the wave that is slowed down. The top part of the wave keeps moving and crashes on to the shore as a breaker.
