Which of twhich of the following forms when ocean surface currents collide? he following forms when ocean surface currents collide?

Eddies are being formed when ocean surface currents collide with each other. An eddy in oceans is defined as a circular current of the waters. The ocean is constantly in motion, the flow or these movements are called as currents. When these currents would pinch off in a section, it would create a current that is circular in motion which is called as eddy. These structures are temporary however they could travel in long distances before they are completely gone. This motion along with currents and gyres are very important in the transport of water and heat in the ocean. Also, it helps in the mixing of the oceans.
