Ocean Waves and Beach Erosion

Alessandra, Haley, Louis, Joe and Brandon

The Wave

• A wave long body of water curling into an arched form and breaking on the shore.

• There are six parts of a wave.• The six parts are the wave crest, wave trough,

orbital path of water molecules, wave height, still water level, wavelength.

Ocean Waves

• Waves that strike the shore at an angle help move sand along the shoreline, forming sandy beaches.

• Waves erosion forms jagged, steep cliffs.• Waves constantly break against the shore

creating rocky formation.

Beach Erosion

• Beach erosion is the erosion of beaches.• This is the removal of beach and the wearing

away of land because of waves.• Beaches are temporary features.
