Document Summary

Result from wind action on water surface. Water in a wave of deep water makes a loop motion as the crest of the wave passes by. Where the influence of wind is less at depths, water travels in smaller loops. Wave orbitals flatten in shallow water due to drag on sea floor. Develops parallel to the shore as waves approach a beach at 90 angle and are refracted. Sediments are carried along shore through . Tides : rhythmic, twice-daily rise and fall of ocean water along coastlines and caused by. Earth and moon orbit about their common centre of gravity. Without gravity, both objects would continue in a straight line. Moon"s gravity deflects earth onto circular orbit. Moon"s gravity on near side is stronger than necessary to maintain orbit, pulling water. Moon"s gravity on far side is weaker, allowing water to spin away from earth. Hydrosphere is pulled into an ellipsoid shape towards moon.
