A headland is eroded and the sand is deposited in an offshore basin Spring tides refer to the largest, daily, astronomicaltidal range during any month. The sediments that make up spits come from a variety of sources including rivers and eroding bluffs, and changes there can have a major effect on spits and other coastal landforms.

Tombolo's are created through the process of longshore drift A tombolo is formed where the spit continues to grow until it reaches an island, forming a link with the mainland, just like bridges. Assuming this is broken, flowing gulfs or passes can frame. 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. E.
