Ocean Temperature, Salinity and Density.

As oceans become deeper, the water pressure ___________________.

• increases

• decreases

• stays the same

Temperature and salinity variations in ocean water cause:

• Mid-ocean ridges
• Horizontal and vertical ocean currents
• Refraction of ocean waves
• Ebb and flow of the tides

Where is ocean water the densest.

• The surface
• The middle
• The bottom
• Lake Michigan

The water layer within which the temperature decreases rapidly with depth. (This layer acts as a density barrier to vertical circulation.)

• surface

• mixed layer

• Ekman Spiral

• thermocline

This layer of water is found at the surface, which has low density and is warmed by sunlight.

• thermocline

• isotherm

• mixed layer

• bottom water

How much salt is in something is called_____________

• Salinity
• Evaporation
• Seamount

The only part of the open ocean that receives enough sunlight to support the growth of algae is

• Intertidal Zone
• Around Hot Vents
• Deep Zone
• Surface Zone

Deep Ocean currents are a result of

• Global Wind Patterns
• Earth's Rotation
• Density
• All of the above

Two types of water currents are

• local and global
• sea and land
• surface and deep
• warm and cold

Constantly moving system of deep-ocean circulation driven by temperature and salinity. It moves water around the globe.

• California Current
• Global Conveyor Belt
• Surface Currents
• Gulf Stream
