• Convection Currents
• Temperature and salinity

Why are surface currents at the surface of the ocean?

• colder temperature
• colder temperature & more salinty
• warmer temperature & less salinty
• less salinty

 The density of ocean water is influenced by what two factors?

•  Salinity and temperature
• Water color and chlorophyll
•  Dissolved gases and dissolved solids
•  Dissolved carbon and trace elements

Warmer water will remain ______ because ________

• at the surface; lower density than cool water

• at the surface; higher density than cool water

• deep; lower density than cool water

• deep; higher density than cool water
