What is the main difference between tidal flats/mud flats and lagoons? lectures | What persistent behavior of waves produces longshore drift? Standing Waves Resonance Waves are disturbances that are generated on or beneath the sea surface. The orbits of the water molecules are circular. Water depths are less than 1/20 the wave length. http://dusk.geo.orst.edu/oceans/waves.html, It is the energy of the wave, not its mass that is in motion. They have very long periods and very large heights. Adding water to materials on a slope can reduce ____ and cause mass wasting to occur. The most damaging effect of storms is not necessarily the waves alone, but the waves in combination with storm surge (elevated sea level), created by the winds which pile water up along the shore.
