Term | Definition |
---|---|
salinity | how much salt the water contains |
current | a mass of circular moving |
tides | periodic rises and falls of large bodies of water |
deep ocean currents | caused by temperature and salinity; form circular pattern in the ocean that form when dense sea water sinks beneath less dense water |
Northern Hemisphere | moves currents clockwise |
Southern Hemisphere | moves currents counter clockwise |
Gulf Stream | is a surface current that moves warm water northeastward toward Great Britain and Europe |
Coriolis Effect | rotation of the Earth and wind |
Surface currents | caused by the Coriolis effect that moves water horizontally and moves only the upper few hundred meters of water |
Waves | is a rhythmic movement that carries energy through matter and space. In the ocean, they move through seawater. |
Ocean currents | are a mass flow of ocean water |
Density Currents | Deep in the ocean, waters circulate not because of wind but because of density differences |
density | how solid a substance is |
