Sandspits
Sandspits are products of long-shore drift and river deposition. Longshore drift is the movement of beach materials like sand, gravel, and mud. This is caused by ocean current, winds moving water and other materials along the shore.

A bay or an inlet at the coast may be subjected to deposition by the incoming silts and sands from the interior brought by the rivers.
The deposits of sands and other materials may be attached to one end of
the main land while the other end is suspended in the Sea.
