Ocean Energy
What location on Earth receives the most of the suns energy?
Equator
Does cold water sink or rise?
Sink
The mass per unit volume of something...
Density
The saltiness of water...
Salinity
Why do gyres make trash group up in large piles?
They flow in circular motions and trash gathers in the center.
What pattern do surface currents flow in?
Circular/Spiral
Sun's energy or getting closer to the equator.
What 'effect' causes surface currents to flow in different directions in the northern and southern hemisphere?
The Coriolis Effect
What type of energy does the wind give to the surface of the ocean?
Kinetic
Explain how deep currents are formed.
Cold water sinks to the bottom of the ocean and flows.
If a lot of salt was dumped in the ocean in one spot, what kind of current would it make?
A deep current - a lot of salt would make a high density.
The movement of matter due to differences in density is...
Convection
How does energy from the sun contribute to surface currents?
The suns energy and uneven heating makes wind, and wind makes surface currents.
When deep currents upwell, what type of water does it bring to the surface?
Cold and nutrient-rich
Do surface currents in the northern hemisphere flow clockwise or counterclockwise?
Clockwise
Ocean currents that flow in large, circular movements
Gyres
