The drift occurs due to waves meeting the beach at an oblique angle, moving sediment down the beach in a zigzag pattern. The general form of a spit is usually not straight but curved shoreward. It develops in places where re-entrance occurs, such as at a cove's headlands, by the process of longshore drift by longshore currents. A. A baymouth bar completely separates the bay from the ocean and is formed in much the same way that a spit is formed, through deposition caused by the longshore drift.

A well-known spit in the UK is Spurn Point at the Humber; it is approximately 4.8km (3.0mi) long. Roads or bulkheads built along bluffs can drastically reduce the volume of sediment eroded, so that not enough material is being pushed along to maintain the spit.

Deflation and sheet wash remove fine-sized materials leaving coarse, weathered, rock fragments concentrated at the surface. A bay-mouth bar is a sandbar that stretches across a bay, separating it from the ocean (Figure 12.24).
