Question

State the difference between ocean currents and tides.

Answer 1

Wave - These are the surface waves mostly formed due to friction of wind over the surface of water resulting in circular movement or water particles which forms waves.
Ocean Currents - They are the movement of water caused due to the differences in density, temperature, salinity of water at different places of oceans.

Answer 2

Tide tends to go up and down whereas currents move to left and right.

Explanation:  

• Waves are periodic changes in the water surface height caused by the wind. The height of any wave depends upon the speed of wind and distance with the surface over which the wind blows.  
• Tides are the periodic change in the ocean level which is resultant of the gravitational force applied by the moon and the sun.
