What are the forces behind the surface currents known as gyre?
1. In the northern hemisphere, the westerlies are winds that blow water from east to west.
2. The gyres are made up of currents set in motion by winds and gravity.
3. Surface currents are deflected at an angle due to the Coriolis effect.
4. The trade winds start a current that is turned by the Coriolis Effect into a eastward flow along the equator.
5. Topography determines the location, size, and shape of the gyres.
6. Thermohaline circulation patterns move surface water from equatorial regions to the poles.

Answer 1

1. the westerlies goes from west to east
2.gyres are made of winds
3. That is true
4. The trade winds are point to west.
5. Topography determine how high the mountain are.(fewtures)
6. The thermohaline begins in the Earth's polar regions. When ocean water in these areas gets very cold, sea ice forms. The surrounding seawater gets saltier, increases in density and sinks. Winds drive ocean currents in the upper 100 meters of the ocean's surface.
