a convection current wind
an example of a weather system on a small scale sea breeze
radiation from the sun UV light
which fluid rises hot fluids
rising air forms a blank pressure air mass low
low air pressure air mass will eventually move,in a stream, outward across the ocean- such movements of air, high up are called jet streams
cooling air contracts and descends
which fluid sinks cold fluid
cooling, sinking air mass is called high pressure air mass
higher density equals greater pressure
air from the cold sea breeze will push the warm air mass upward sea breeze
describes how much salt is in a body of water salinity
two processes which lead to high salinity evaporation and freezing
process of evaporation allows pure water to escape leaving behind the salt crystallization
two regions of highest salinity in the ocean at the poles and the equator
coastal waters are warm, nutrient-poor and blank salinity low in salinity
winds sweep away surface waters, cold dense water from below, moves in to replace it upwelling
opposite of convection upwelling
a connection of two liquid filled pistons hydraulic system
