The word "tides" is a generic term used to define the alternating rise and fall in sea level with respect to the land, produced by the gravitational attraction of the moon and the sun.
Ocean levels fluctuate daily as the Sun, Moon and Earth interact. As the Moon travels around the Earth and as they, together, travel around the Sun, the combined gravitational forces cause the world's oceans to rise and fall. Since the Earth is rotating while this is happening, two high tides and two low tides occur every day. There is about 12 hours and 25 minutes between the two high tides.
Tides are the periodic rise and falling of large bodies of water. Winds and currents move the surface water causing waves. The gravitational attraction of the moon causes the oceans to bulge out in the direction of the moon. Another bulge occurs on the opposite side, since the Earth is also being pulled toward the moon (and away from the water on the far side).
When the Sun and Moon are aligned, there are exceptionally strong gravitational forces, causing very high and very low tides which are called spring tides, though they have nothing to do with the season. Spring tides occur during the full moon and the new moon.
Neap tides occur when the gravitational forces of the Moon and the Sun are perpendicular to one another (with respect to the Earth). They are especially weak tides. Neap tides occur during quarter moons.
