What forces cause and influence waves?
This lesson examines the variations in the surface of water as energy is transferred in a direction by the water. The influence of wind, the vocabulary of wave structure, the changes that occur in waves as they approach shore and their impact on the shore will be described. Additionally, this lesson will examine waves withing contained bodies of water and the dramatic rise that occurs during tsunamis.
