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.
Lesson Summary. Tides are the periodic rise and fall of ocean waters. The gravitational pull of the moon and sun creates the tides. When the gravitational pull is at its highest point, the result is high tide, which is the highest level of the tide. When the pull is at its lowest point, we see low tide, or the lowest level of the tide.
