What Causes Ocean Currents?

By: Cynthia Munoz

3 BIG Ideas I have learned.

  • Ocean currents can be generated by wind
  • There are two distinct current systems in the ocean—surface circulation, which stirs a relatively thin upper layer of the sea, and deep circulation, which sweeps along the deep-sea floor.
  • Their patterns are determined by wind direction

2 Questions I still have

  1. How do currents affect sailing ships?
  2. Do ocean currents affect the sea life?

1 way the article affects our daily lives.

The ocean currents depend on the heat and wind and all that daily.
