Describe the various factors that influence ocean currents and discuss their multi-dimensional impact

flows in the direction

II. Secondary Factors: Temperature & Salinity which also influence speed & direction.

Multi-Dimensional Impact

I. Geographic Impact ⊙ Desert Formation: due to cold current which have desiccating effect that inhibit convection

Eg Namib desert (Benguela current), Atacama desert (Californian current)

⊙ Warm Weather: due to presence of warm current. Eg Britain it never too cold due to Warm North Atlantic Drift

II. Economic Impact ⊙ Keeps both Ice Free: in Britain & Norway due to warm North Atlantic Drift

⊙ Helps Ships: which flow with ocean current for speed & safe fuel

⊙ Upwelling: of cold nutrient rich water causes plankton growth & fishery (Eg Peru Callect)

⊙ Fishing Grounds: formed due to mostly mixing of cold & warm current.

(Eg) Japan east (Kuroshio & Oyashio current) (Confluence) (Convergence)

Ocean currents play a crucial role in maintaining Earth's heat balance & enable budding fishing industry & commerce.
