High and low tides diagram. The moon has a much greater impact on tides than the sun because it is much closer. Floods of this sort block. This animation shows the tidal force in a view of earth from the north pole.

As regions of earth pass through the bulges they can experiences a high tide. Shortly after full or new moon a locality will experience its highest high waters and lowest low waters of the lunar month and a tides in this period are called spring tides. The highest point of the rise is called high tidethe lowest point is called low tidemost places have two high tides and two low tides each day.

Neap tides when the moon is at first or third quarter you can find more on moon phases here then the moon and sun are exerting forces from two different directions and the overall effect on the water is less so the high tides are lower than average and the low tides are higher than the average and we call these low tides neap tides. The highest high tide occurs during this tide. Tides have caused a lot of trouble recently.

Occurs when the sun earth moon are in a straight line. Spring tides occur during a full or new moon when the earth. This is because the sun and moon are pulling the earths water in two different directions.

These variations affect the high tidal wave and hence the range of the tide the difference in level between successive high and low waters.
