Ocean Currents 1
The term which refers to the saltiness of water.
What is salinity?
Air or water does this when heated: rises or sinks
What is rises?
What are ocean currents?
This part of the Earth receives the most direct sunlight.
What is the equator?
This is another name for deep ocean currents; it means heat and salt.
What is thermohaline?
What is the sun?
This happens when air or water cools : sinks or floats
What is sinks?
These currents are driven by the global winds.
What are surface currents?
This part of the Earth receives the least amount of direct sunlight.
What are the poles?
Which is more dense warm or cold water?
What is cold?
These two things affect the density of water
What is temperature and salinity?
As this increases, the density of air or water decreases.
What is temperature?
This current brings warm water to the poles and regulates the climate of the east coast of the United States.
What is the Gulf Stream?
True or False: Earth's oceans prevent the Earth from getting too hot or too cold.
What is true?
Deep ocean currents follow one path around the Earth called this.
What is the global conveyor belt?
The amount of matter in a volume or space. one of the driving forces of ocean currents
What is density or density differences?
Another name for the impact on wind and ocean currents caused by the rotation of the Earth.
What is The Coriolis Effect?
Surface currents create large systems of rotating water in the ocean called these.
What are gyres?
Which heats up faster, land or water?
What is land
As you increase the salinity of water, you increase this characteristic of water.
What is the density?
Where do the warm ocean Currents come from?
What is the equator?
True or False: Water has a LOW specific heat.
What is false?
Gyres in the Northern Hemisphere turn in this direction: clockwise or counterclockwise
What is clockwise?
True or False: Warm surface currents bring water from the poles to the equator.
What is false?
The term used to describe deep ocean currents returning to the surface and bringing nutrients for living organisms.
What is upwelling?
