Ocean Currents Causes

Currents are the movements of the ocean produced by various causes. It may be divided into general and particular. The former depending on fixed and general causes which is always preserve the same direction and limits while the latter resulting from local and temporary ones vary both. The grand movement of the ocean from east to west or the equatorial current has a more complicated origin and the trade wind, so far from being the cause as has been supposed by some are probably in part the effect of this current. (J. H. Tuckey, 1815)
Ocean currents are water movement and circulation forms that effect climate zones and weather patterns around the world. The directions these currents take can be affected by climate, actions of celestial bodies

The different types of currents are referred to the surface or thermohaline that depends on their depth. It is created among other things such as wind, water density, the topography of the ocean floor and the coriolis effect. (Ashe, n.d)
Through the wind factor, it is the biggest factor that can create the surface of the currents. This happen when the strong winds are moving across the surface of the water. However, these strong winds are not a major winds. The major winds that most frequently effect the creation of ocean currents are the Westerlies. It blow from west to east and the Trade Winds are blow from east to west. (Ashe, n.d)
Next factor that create the currents is water density. This factor caused by the total of salt in a body of water and its temperature. Water with a higher salinity or a colder water is more dense and possible to sink while the sinking water pushes the water below it up. Through this process, it formed a combination of sinking and rising in the same area that can causes a current. (Ashe,

Ocean currents are impelled by different forces. Such forces can incorporate the wind, tidal patterns due to the gravitational pull from the sun and moon, the Coriolis force and water temperature. An ocean current can move for some miles. The way a current flow is usually reliable. (Zmuida, n.d)
Wind can impel ocean currents to move due to resistance. Contingent on the Earth's rotation, winds can move to the top surface of the ocean and creating the surface of the currents. Then, a gyre will formed due to the surface of the current. A gyre is a spiral movement that formed on an ocean's surface. (Zmuida, n.d)
Therefore, currents can be moved by tidal patterns. As the tides rise and fall, ocean currents will be moved. As indicated by the National Oceanic and Climatic Organization, tides are produced by the gravitation between the Earth, the sun and the moon. This gravitational force influences the Earth's oceans. Currents in the oceans will happen along the tides, creating tidal currents and flows. (Zmuida,
