The spit bends slightly west or east, changing its direction gradually, depending on the conditions of the tides and weather. Deep water waves in the open sea are waves ofoscillation. This process is called longshore drift. These currents are caused by the same waves that cause the drift.[1][2][3]. C. The main channel is changed from a straight one to a meandering one to allow higher discharge to make it to base level. C. This percentage is low, and so is the volume of glacial ice, so melting it will have little effect on humans. How are spits, hooks, and baymouth bars formed? Bay-mouth bars may extend partially or entirely across the mouth of a bay; bay-head bars occur at the heads of bays, a short distance from shore. How is a bay mouth bar formed?
