1. Properties of Ocean Water

2. Chemical Properties of Ocean Water Determines composition Determines composition Enables it to dissolve other substances Enables it to dissolve other substances

3. Physical Properties of Ocean Water Temperature Temperature Density Density Color Color

4. Elements in the Ocean Chlorine Chlorine Sodium Sodium Magnesium Magnesium Sulfur Sulfur Calcium Calcium Potassium Potassium

5. How do these elements get into the ocean Rivers deposits are carried to the ocean Rivers deposits are carried to the ocean Evaporation of ocean water leaves minerals behind Evaporation of ocean water leaves minerals behind

6. Dissolved Gases Nitrogen Nitrogen Oxygen Oxygen Carbon Dioxide- most easily dissolved Carbon Dioxide- most easily dissolved

7. Temperature Influences how substances dissolve in water Influences how substances dissolve in water Solids dissolve better in warm water Solids dissolve better in warm water Gases dissolve better in cold water Gases dissolve better in cold water

8. Temperature How does temperature of water influence the composition of ocean water? How does temperature of water influence the composition of ocean water?

10. Surface Temperature Infrared rays heat the water Infrared rays heat the water Mixing of water distributes the heat down to about 300 meters Mixing of water distributes the heat down to about 300 meters Depends on the latitude Depends on the latitude

11. Thermocline The point at which the temperature of ocean water drops dramatically The point at which the temperature of ocean water drops dramatically Less dense warm water can not mix with dense, cold water Less dense warm water can not mix with dense, cold water

12. Density Factors Salinity Salinity –More dissolved gases = More dense Temperature Temperature –More dense = cold –Less dense = warm
