Lecture on Ocean Forces

This lecture introduce on Ocean Forces. Ocean Currents are influenced by two types of forces; 1. Primary Forces–start the water moving. The primary forces are: Solar Heating, Winds, Gravity and Coriolis effect. 2. Secondary Forces–influence where the currents flow. Solar heating cause water to expand. Near the equator the water is about 8 centimeters high than in middle latitudes. This cause a very slight slope and water wants to flow down the slope. Winds blowing on the surface of the ocean push the water. Friction occurs between the wind and the water’s surface.
