Breeze,Current,Fluid
Question | Answer |
---|---|
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 |
