undefined The three factors that contribute the most to the formation of coastal currents are:

1. Wind: Wind plays a significant role in generating coastal currents by exerting force on the surface of the ocean. Persistent winds blowing parallel to the coastline can create longshore currents, while strong onshore or offshore winds can cause coastal upwelling or downwelling, respectively.

2. Coriolis Effect: The Coriolis Effect, caused by the rotation of the Earth, influences the direction of coastal currents. In the Northern Hemisphere, coastal currents are deflected to the right, while in the Southern Hemisphere, they are deflected to the left. This deflection leads to the formation of coastal boundary currents along the coastline.

3. Shape of the Coastline: The shape and orientation of the coastline play a crucial role in shaping coastal currents. Irregular coastlines, such as bays, headlands, and inlets, can cause the redirection and intensification of currents. Narrow passages and constriction points can accelerate water flow, leading to the formation of strong tidal currents and jets.
