A. changing the amount of solar energy that is received over time across different parts of the planet A. slightly clayey sand A spit forms when wave trains (groups of waves moving in the same direction) produced by strong winds approach a land mass at an angle of less than 90 o (Figure 2). Vegetation may then start to grow on the spit, and the spit may become stable and often fertile. D. Esker, 208. The drift occurs due to waves meeting the beach at an oblique angle, moving sediment down the beach in a zigzag pattern. At this point only, we get net transport of water in wave direction.

These processes require an external source of oxygen and can occur only at Earth's surface. As wave enters shallower water than wave base, its develops friction with sea floor. 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.
