How are spits, hooks, and baymouth bars formed? Building and lengthening of the superaqueous portion of a spit or bar is caused by the transportation of material from the shore toward the distal end of the structure by the swash and backwash when the waves break obliquely on the shore. The bulges maintain the same position relative to the Moon (or Sun). . Thus, they most commonly occur across artificial bay and river entrances due to the loss. 196.

How does wave refraction affect the crest and trough orientations of incoming waves along a beach? Evidence of wave action (symmetrical ripples). A spit, which forms where a shoreline changes direction, is protected from wave action. When a growing spit crosses a bay, a baymouth forms. For a passing wave, the depth below which the motion of water particles become negligible is equal to Neap tides are produced when the Moon is at right angles to the line connecting the Earth and Sun.
