Which of the following is not one of the main drivers for surface ocean currents?
a. ocean instability due to the vertical temperature profile of the top 100 meters
b. wind stress at the ocean surface
c. the coriolis effect

A)  Ocean instability due to the vertical temperature profile of the top 100 meters

Explanation:

Ocean instability are due to the vertical temperature profile of the top 100 meter are not main drivers for the surface ocean current as, the surface ocean currents are derived by the velocity of the wind and the coriolis effects. Deep water current and the circulations current are driven by the changes in the salinity and the temperature which is also known as density currents.  

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.

the answer is option c.

explanation:

recycled water alludes to the water that being utilized again after it already  used for farming purposes.   this kind of water frequently contains pharmaceutical gathering due to the compound compost that is utilized for the plants is consumed into the water.
