Answer :
The rotation of earth deflects some of the currents. So if there is not rotation, then the currents will be a lot larger than the ones that we have today.
Answer;
-The currents would only travel north, south, east, and west
The surface currents would be affected if the earth didn't rotate in that the currents would only travel north, south, east, and west.
Explanation;
-Ocean currents can be generated by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes.
-The Coriolis effect describes how Earth's rotation steers winds and surface ocean currents. This effects causes freely moving objects to appear to move to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. Therefore, without the rotation of the earth, the surface currents would travel, north, south, east and west.
