What happens to Density as temperature increases?
Density increases.
What causes salinity to decrease?

What is an Aquifer?
An aquifer is an underground layer of rock that holds water.
Where is most of our drinking water found?
Rivers & Lakes
What is the mid-ocean ridge?
Continuous underwater mountain range.
How does depth affect pressure?
As depth increases pressure increases. As depth decreases pressure decreases.
What causes salinity to increase?
Evaporation
What has to happen for water to change from a liquid to a gas?
Gain Energy
Is groundwater readily available? Why or why not?
No, because we have to drill of it.
What is a seamount and a deep-sea trench?
Seamount- are mountains that are completely underwater.
Deep-Sea Trench- a very steep-sided narrow cut in the sea floor.
What are the two main gases found in our oceans?
Oxygen & Carbon Dioxide
How will the freezing of ice affect salinity?
Increases Salinity.

What are the different parts of the sea floor?
What moves the warm water to the surface and the cooler water to deeper parts of the ocean?
Convection Currents
How does salinity affect density?
Higher Salinity=More Dense
Lower Salinity=Less Dense
