Tides Movie What are normal tidal ranges? Where is the tidal range greatest in the world? What is the tidal range at this place?

Tides – cyclic rise and fall of ocean waters l Two High Tides and Two Low Tides a day l Tides change about every 6 hours l Tides are caused by the gravitational pull of the Moon and Sun on the water l Moon revolving around the Earth and Earth’s rotation responsible for tide changes l

Tidal Ranges Spring Tides – Greatest tidal range, during New and Full Moon phases l When Moon and Sun are in straight line with the Earth l Neap Tides – smaller tidal range, during First Quarter and Last Quarter l When Moon and Sun are pulling at 90 degree angle from one another l
