6.1 and 6.2 Science

It is the study of Earth's Ocean:

• Geology

• Ocean Movements

• Oceanography

• Streams

It is the measure of the quatity of dissolved salt in seawater:

• Salinity

• Sodium

• Density

• Minerals

The Region where cold , deep water meets the sun-warmed, near-surface water is:

• Temperature

• Density

• Pressure

• Thermocline

They are two main factors that determine the density of seawater:

• Pressure and Temperature

• Mass and Density

• Salinity and Temperature

• Sodium and Pressure

Why do icebergs float?

• Because of the Salinity in them.

• Because they are slightly less dense than water.

• Because they are shallow.

• Because they are a type of solid that can float in any liquid.

They are large streams of ocean water that flow at or below the surface.

• Ocean Currents

• Gulf Streams

• Turbidity

• Upwellings

How are the surface currents that move in a circular path called?

• Turbidity Currents

• Upwellings

• Gyre

• Surf

In the Atlantic Ocean north of the Equator, several minor currents join to form...

• The Peru Current

• The Subsurface Currents

• The Gulf Stream

• Turbidity Current

Ocean Currents that flow beneath the surface are..

• Surface Currents

• Subsurface Currents

• Turbidity Currents

• Upwellings

This phenomenom occurs when mud or silt mixes with sea water, changing the density of a current. What is the name of this event?

• Turbidity Current

• Upwellings

• Countercurrent

• Waves
