TIDES

- The rise and fall of the sea level as a result of the forces between the earth, the moon and the sun is called a tide.

- The interval between two tides is 12 hours and 26 minutes.

Spring Tides

- When the earth, the moon and the sun are in a straight line (also called SYZYGY), the sun assists the gravitational pull of the moon, creating a condition of higher high tides and lower low tides known as spring tides.

Neap Tides

- When the sun and moon are at right angles to the earth, the sun partially contracts the pull of the moon, producing lower high tides typical of a neap tides.
