The Bay of Fundy is known for having the highest tidal range in the world. Rivaled by Ungava Bay in northern Quebec, King Sound in Western Australia, Gulf of Khambhat in India, and the Severn Estuary in the UK, it has one of the highest vertical tidal ranges in the world.
Generally, the tides are greatest near the time of the new moon and full moon. That is when the gravity of the sun and the moon are pulling together instead of at an angle-your textbook should have an illustration of this.his would be Full and New moon phases. Similarly we have the weakest tides when the sun and moon are acting at right angles on the earth. This is during 1st and 3rd quarter.
