As warm water moves to higher latitudes, the salinity changes. Unlike surface water, deep water ocean circulation is due to density differences. Which of the following statements correctly identifies the factors responsible for the process? o Colder water has a higher salinity and sinks. o Less dense water sinks below more dense water. o Global wind patterns control all ocean circulation. o Water that is warmed at the surface sinks, forcing cold water to rise from below.
