Any beach goer is familiar with the basic motion of the ocean in the form of waves and tides. Whether he's jumped waves with his children or quickly moved his towel out of the way of an incoming tide, he knows the power of water, but he may not know what is behind those forces. This book covers the basics of both waves and tides, including types of waves, tidal terms, and the science of both.
