• A. Ocean currents and trade winds
  • B. Wave erosion
  • C. Long shore drift and wave depositions ✓
  • D. Westerly winds


The answer to the question is: C. Long shore drift and wave depositions

Spits are elongated ridges of sand or shingle that extend from the mainland into a body of water.

Longshore drift, also known as littoral drift, is the process by which sediments such as sand and pebbles are transported along the coastline by the action of waves and currents. This movement of sediment occurs in a zigzag pattern parallel to the shoreline, resulting in the formation of spits and other coastal landforms. As waves approach the shore at an angle, they carry sediment along the coast in a process known as longshore transport. When these sediments encounter a change in wave energy or direction, they may be deposited to form a spit.

Wave deposition refers to the process by which sediment carried by waves is deposited in a particular location. As waves approach the coast, they carry sediment such as sand and gravel. When these waves lose energy, they deposit their sediment load, contributing to the formation and growth of spits.

The formation of spits is also influenced by factors such as prevailing wind patterns, tidal currents, and coastal geomorphology. However, longshore drift and wave deposition are primary mechanisms responsible for the creation of spits.
