The Earth: Shape and Size-Ocean Currents

Here the study generally focuses on the shape and size of the ocean current and also the nature which helps in the movement of the currents. The movement which is generally in horizontal form is called the currents which generally range from the magnitude of a few centimeters such as 4 m/s. The characteristics of the ocean current according to the surface and its speed are about 5 to 50 cm which is generally 2 to 20 inches if calculated per second. The currents are generally seen diminishing in intensity with an increasing depth of the ocean. 

Therefore it can also be said that the coriolis effect, continents or the landmasses generally influence the ocean current by the end number of causes which is deflected from the path that is original. By studying the ocean map and the current it has been evaluated that the direction of the change and the current movement is deflected by the landmasses. 

Type of the ocean currents

• Horizontal Currents.

•  Surface Current.

• Vertical Currents.

If the ocean currents are divided according to the circulation then it can be said that it is of 2 types, wind-driven circulation of the ocean currents, which is seen getting forced by the surface of the sea and thermohaline circulation ocean currents depending on the water density and its variation based on the surface of the ocean.These ocean currents are generally caused due to the movement caused by the winds, differences in the density of the water bodies and the landmasses. The ocean currents on the surface of the water are generally driven by the wind system globally and are fueled by the help of the sun and the energy provided by the wind. Ocean currents are also caused sometimes due to the high salinity of the ocean water and also due to the rise in temperature of the water bodies due to climate change.

• Direction in which the ocean currents move

The ocean currents generally move in a clockwise pattern in the northern hemisphere and in the southern hemisphere, the ocean currents generally move in an anticlockwise direction. The wind plays a very important role if the surface of the ocean currents is taken into consideration. If the effect on the climatic condition is taken into consideration due to the movement of ocean currents it has been evaluated that the planet and its temperature is generally warming. The ocean current generally moves in two directions, horizontal and vertical direction.

• Nature of the ocean current

The nature of the ocean current plays a very important role as it highly impacts the aquatic life of the earth and also the climatic conditions of the globe. Ocean life also plays a very important role as it has been evaluated that life in the ocean has laid down a great volume of salacious rock and carbonate rock.The currents in the North equatorial part are generally the Gulf Stream, the northern Planate current at the Canadian current.

Conclusion 

Hence, it can be concluded that movement of ocean current is very important. One of the most important aspects of it is the climatic condition. The exchange of heat is between the ocean current movements and also the atmosphere also causes a great heat generation that causes changes in the climatic condition of the earth. Hence, it is important because it maintains the right functioning of the marine ecosystem and also helps in creating a great balance in between the system of the earth.
