Ocean currents are directed, continuous movements of ocean water. They are found on the ocean’s surface and in its depths, and can be local or global. Ocean currents are driven by winds, water density, and tides. Sea floor features and coast lines can influence the speed and direction of currents.
To better understand climate zones & ocean currents…
LET’S BREAK IT DOWN!
The Coriolis effect is a global wind pattern that is caused by the rotation of Earth, which rotates on its axis every 24 hours. Because of the rotation and tilt of Earth’s axis, certain latitudes move faster than others. For example, the North and South poles have less distance to move to make a complete rotation and are moving at a slower rate. The Equator has the furthest distance to move and is moving at the fastest rate. As air currents move from one latitude to another, they begin moving at the same rate of speed as their point of origin. However, the latitude that they are moving towards may be moving faster or slower. Consequently, the air currents “bend” because the Earth under them is moving at different rates. Air currents are deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
