FLASHCARD QUESTION

Front

What is density in relation to ocean water?

Back

Density is the mass of water per unit volume, which is affected by temperature and salinity.

4.

FLASHCARD QUESTION

What happens to materials that are less dense than water?

Back

Materials that are less dense than water will float.

5.

FLASHCARD QUESTION

Front

What is the Thermohaline circulation?

Back

Thermohaline circulation is a global system of surface and deep ocean currents driven by temperature (thermo) and salinity (haline) differences.

6.

FLASHCARD QUESTION

Front

What does salinity refer to?

Back

Salinity refers to the concentration of salts in water, which affects the density of ocean water.

7.

FLASHCARD QUESTION

Front
