Which ocean current is the only one to completely circle earth?

West Wind Drift is ocean current that only continues in circle around the circumference of the Earth, it brings the most volume of water of all currents. It go around the earth, crossing the Atlantic, Indian, and Pacific oceans; the cold Bengal, West Australian, and Peru currents branch off from it in the oceans. 

sediment layers stop spreading when they reach a barrier or they run out of sedimentary material. lateral spreading is the movement of gently to steeply sloping, saturated soil deposits caused by earthquake-induced liquefaction. i hope this . : )
