Put the liquids in order from most dense to least dense?

• 4, 3, 2, 1
• 1, 2, 3, 4
• 3, 4, 2, 1, 
• 4, 3, 1, 2

______ causes deep ocean currents

• The Coriolis Effect

• gravity

• wind

• density differences

______ causes surface currents.

• The Coriolis Effect

• gravity

• density differences

• wind

Decreasing ocean temperature causes the density of the water to ______.

• decrease

• increase

• stay the same

• fluctuate

Warm ocean currents generally come from

• The North Pole
• The South Pole
• The Equator
• Both A and B

Cold ocean currents generally come from

• The North Pole 
• The South Pole
• The Equator
• Either Pole

As Density  increases

• Temperature decreases
• Temperature increases

Temperature  increases

• Density increases
• Density decreases

As salinity  increases

• Density increases
• Density decreases

Ocean depth  increases & Salinity  increases then

• Temperature decreases because cold water is more dense and sinks
• Temperature increases because cold water is more dense and sinks
