  • What Causes Ocean Tides? Reference

    Several times a year, oceans worldwide experience particularly strong tides called spring tides. Despite the name, these tides have nothing to do with springtime, but instead pertain to the appearance of new and full moons. During spring tides, the moon, sun and Earth become aligned, thus amplifying the effect of gravitational attraction.

  • Ocean Tides Background Ocean Motion and Surface Currents

    Tides can be thought of as progressive planetaryscale waves that propagate across ocean basins wave crests are high tides and wave troughs are low tides. A tide wave's length is considerably greater than the depth of the ocean so it behaves as a shallowwater wave.

    Waves of water do not move horizontally, they only move up and down (a wave does not represent a flow of water). You can see a demonstration of this by watching a floating buoy bob up and down with a wave it does not, however, move horizontally with the wave.

  • The science of surfing: A simple introduction to ching

    Tides have nothing to do with waves. Tides are caused by the Moon and the Sun working together to "pull" the sea back and forth with their gravity, rather like a giant blanket moving up and down a bed. Tides change the depth of the water on your beach. When the tide is "in" the waves come in further and break later when the tide is "out" the

    The key to understanding how the tides work is understanding the relationship between the motion of our planet and the Moon and Sun. As the Earth spins on its own axis, ocean water is kept at equal levels around the planet by the Earth's gravity pulling inward and centrifugal force pushing outward.

  • NOAA SciJinks :: What causes tides?

    The sun causes tides just like the moon does, although they are somewhat smaller. When the earth, moon, and sun line up—which happens at times of full moon or new moon—the lunar and solar tides reinforce each other, leading to more extreme tides, called spring tides.

    Spring tides occur during the full moon and the new moon. Neap Tides During the moon's quarter phases the sun and moon work at right angles, causing the bulges to cancel each other. The result is a smaller difference between high and low tides and is known as a neap tide. Neap tides are especially weak tides.
