Question

1. What are the causes of origin of ocean current?

2. What is the differnce between ocean current and ocean wave?

3. What is EL-Nino?​

Answer 1

Explanation:

1. Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. Currents are cohesive streams of seawater that circulate through the ocean.
2. Ocean currents are the continuous flow of huge amount of water in a definite direction while the waves are the horizontal motion of water. Water moves ahead from one place to another through ocean currents while the water in the waves does not move, but the wave trains move ahead.
3. The term El Niño refers to the large-scale ocean-atmosphere climate interaction linked to a periodic warming in sea surface temperatures across the central and east-central Equatorial Pacific.

Answer 2

Answer:

The movement of ocean waters or ocean currents takes place due to the effect of earth's rotation, wind difference, salinity and density of seawater, etc. The current in the ocean is originated due to the combined effect of all these factors acting internally as well as externally.

Difference between waves, tides and currents. Waves for example are influenced by the action of wind on the surface of the ocean while currents are influenced by the heat from the sun on the equator and cooler poles. Tides on the other hand are caused by gravitational forces from the moon and sun.

El Nino is the name given to a slight warming of the surface waters of the Pacific. ... The warmest part of the Pacific Ocean is the region near the equator. Due to the spinning of the earth, the prevailing winds flow from east to west. This pushes the warm waters westwards, towards Indonesia
