Oceanography and Hydrology

TermDefinition
The continuous movement of water from Earth's surface to the atmosphere and back to the oceans Water Cycle
Pollution coming from many different sources such fertilizer and pesticides from farmingwhich runs off into rivers and streams When water becomes more dense, then it will __ Non-point source pollution
Pollution which comes from a specific site EXAMPLE- oil spills Point source pollution
The Sun's heat changing liquid water changing to water vapor Evaporation
Water (in any form) returning to Earth Precipitation
Cool temperatures changing water vapor to liquid water Condensation
Evaporation off of plants Transpiration
Ocean water moving in a regular pattern determined by its temperature and density Currents
The rise and fall of large bodies of water due to the moon's gravitational pull Tides
Occurs when the Sun, Earth, and moon are at an Ninety degree angle, very little tidal range Neap Tide
Occurs when the Sun, Earth, and moon are in a straight line, creates a SUPER big tidal range Spring Tide
The wind's energy moving through ocean water Waves

The gravitational pull of the moon Cause of ocean tides
The apparent "curving" of currents due to Earth's rotation Coriolis Effect
Currents that occur below the surface; caused by high salinity and cool temperatures Deep ocean currents
Currents that occur at the surface; caused by global winds, continental deflection, and the Coriolis effect Surface currents
The amount of salt in water Salinity
Water that becomes more dense due to salinity and temperature changes will ____________ Sink
