  3. Bay of Fundy, Nova Scotia: 21 foot tides! One of the greatest tidal variations on Earth!

  4. High Tide Low Tide

  5. Exactly WHY are there tides • Moon and Sun have a gravitational attraction on the Earth’s oceans which creates a bulge. • As the moon revolves around the Earth, the bulge moves across the Earth’s surface.

  6. Types of Tides • Spring Tide • Unusually high tide. • The sun’s gravitational pull reinforces the moon’s gravitational pull. • Occurs during the new and full moon phase.

  7. Types of Tides • Neap Tide • Unusually low tides • The sun’s gravitational pull is at a right angle to the moon’s gravitational pull • Occurs during the 1st and last quarter moon phases.
