a surface current is warmer becasuse it isn't near the bottom of the ocean its near the top so it gets more heat

Well, honey, a surface current is like the diva strutting her stuff on the runway - it's the flashy, visible movement of water caused by things like wind and tides. On the other hand, a deep current is more like the mysterious loner lurking in the shadows - it's the slow, hidden flow of water deep below the surface, driven by differences in temperature and salinity. So, in a nutshell, surface currents are the show-offs, while deep currents are the silent movers and shakers of the ocean.
An upwelling is a current in the ocean that brings deep, cold water to the ocean surface.

Deep currents
Different pressure levels will vary speed and direction
deep currents streamlike movement of water that flow very slowly along the ocean floor. surface current can influence the climate of land are they flow past.
