As the temperature of ocean water changes from 10 to 30 degrees C becoming warmer, how does the density change?
The water becomes more dense
The water becomes less dense
The density does not change
It is impossible to predict
What is the temperature, salinity, and density like at the surface zone of the ocean (top) as compared to the deep zone (bottom) of the ocean?
colder temperature, more salinity, and more dense
colder temperature, more salinity, and less dense
warmer temperature, less salinity, and less dense
Warmer temperature, less salinity, and more dense
Which of the following statements are true? (Select ALL that apply)
Saltwater is more dense that freshwater
Freshwater is more dense than saltwater
Freshwater layers below freshwater because water (H20) has more mass than salt (NaCl)
Saltwater layers below freshwater because the salt molecule (NaCl) has more mass than the water molecule (H20)
