Request Answer. D. The aquifer is overlain by sandstone or gravel. If the supply is not interrupted, and the spit is not breached by the sea (or, if across an estuary, the river), the spit may become a bar, with both ends joined to land, and form a lagoon behind the bar. Spits are ridges of sand projected from land into the bay (Figure 12.23). Some long beaches extend completely across the mouth of a river or a bay.

Depositional Coastal Landforms or Features A bay-mouth bar is a sandbar that stretches across a bay, separating it from the ocean (Figure 12.24). If an island lies offshore near where the coast changes direction, and the spit continues to grow until it connects the island to the mainland, it is called a tombolo. D. These processes occur at Earth's surface but are considered external because they require no additional energy. Capillary fringe Summary and Conclusions. The deposition of sediment forms a spit but its shape changes as a result of wave refraction. The effect of the Sun on tides is about one-half that ofthe Moon.
