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

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

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