Surface currents generated by wind due to friction related to the circulation of the atmosphere

gyres Huge circular surface currents currents affected by the Coriolis effect you tube clip-coriolis effect https://www.youtube.com/watch?v=i2mec3vgeaI&list=PLH3X9aDkYMD3 CCRgHCKUD03v6gHoLSMeA&index=7

currents affect climate Agree or Disagree Statement 1: When warm water near the equatorial region moves north it causes the climate to warm. Statement 2: When polar water moves south it does not affect the climate because the water is warmed back up.

upwelling rising of cold deep water to replace surface water results in nutrient rich water el nino you tube What is the effect of el nino on Montana weather? https://www.youtube.com/watch?v=WPA- KpldDVc&list=PLH3X9aDkYMD3CCRgHCKUD03v6gHoLSMeA&index =8

Density currents vertical currents driven by density How does dense water move? Polar regions- what do you expect?
