  1. WHAT ARE THE SOURCES OF ENERGY ON COASTS? Rivers deliver sediment to the oceans. How are they distributed and how can the oceans cause erosion?

  2. WHAT ARE THE SOURCES OF ENERGY ON COASTS? Tides

  3. WHAT ARE THE SOURCES OF ENERGY ON COASTS? Tides Waves

  4. WHAT ARE THE SOURCES OF ENERGY ON COASTS? Tides Waves Surges

  5. WHAT ARE THE SOURCES OF ENERGY ON COASTS? Tides Waves Surges Tsunamis

  6. WHAT ARE THE SOURCES OF ENERGY ON COASTS? Tides* Waves* Surges Tsunamis

  7. How do Tides Work? 363,104 km (225,622 mi) 406,696 km (252,622 mi) N

  8. How do Tides Work? If Earth was not also revolving around the Sun , the moon would take 27.3 day complete a revolution. Earth 363,104 km (225,622 mi) 406,696 km (252,622 mi) N Moon As the Earth is moving it actually takes 29.5 days.

  9. Earth 5° Moon N Sun S Moon

  10. Earth covered in Oceans.

  11. Line of maximum gravitational pull Moon

  12. Ocean waters on this side pulled towards line.

  13. Ocean waters on this side pulled towards line.

  14. Ocean waters “shallower” than average. Low tide.

  15. Ocean waters “deeper” than average. High tide.
