The moon and the tides

The tides are caused mainly by the gravitational pull of the moon. The sun exerts a weaker influence. When the moon and sun’s gravitational pulls line up they produce especially high and low tides, called spring tides. When they are at right angles they cancel each other out, resulting in a low tidal variation known as neap tides.
