How are spits formed and connected?
It is connected to the mainland at one end. A spit thus has two ends. The end jutting out onto the water is called the distal end, and the one attached to land is called the proximal end. How Are Spits Formed? Spits are usually formed when longshore currents producing a longshore drift strike the beach at an angle.
