Wind Direction
Components of waves
crest
trough
Wavelength: the distance between two troughs or two crests
The GREATER the wavelength the lower the frequency
The SMALLER the wavelength the greater the frequency
Breakers
Beaches

Larger waves have more energy to pick up sediments which leads to more erosion
Smaller waves have less energy to pick up sediments which leads to deposition
Prevention of beach erosion
Beach communities have tried many ways to prevent beach erosion

Tidal Range and landforms
Ocean Temperature
Ocean Currents and Climate
Currents affect climate for two main reasons:
1. Water has a high specific heat capacity
2. Thermal energy moves from high to low
Gulf Stream
Labrador Current
