ACING EAPS 100, FINAL EXAM WITH ESSENTIAL A+
QUESTIONS AND ANSWERS
salt water in the ocean
dissolved salt increases oceans water density without changing the volume
density of water
controlled by temp and salinity
ocean currents
a band of flowing water that moves faster than adjacent water
Coriolis effect
the deflection of a moving object relative to the surface of a spinning object beneath
northern hemisphere (Coriolis effect)
cause objects initially moving north, from a lower to higher latitude, to deflect to the right
(east)
southern hemisphere (Coriolis effect)
objects moving north deflect to the left (west)
upwelling
a surface flow that moves water away from the shore causes upwelling. upwelling brings up
nutrients and fosters the growth of algae near shore.
downwelling
a surface flow that moves toward the shore causes downwelling
thermohaline circulation
the rising and sinking of water driven by density. results in a global scale conveyor belt that
circulates water throughout the whole ocean.
tide-generating force
the combination of forces that cause the tides to occur
gravitational attraction
from the sun and moon
centrifugal force
, caused by the revolution of the earth-moon system. produced by revolutions of the earth and
moon (and earth and sun) around their common center-of-gravity (mass)
tidal bulges
the larger (sublunar) tidal bulge always faces the moon and the smaller (Secondary) tidal bulge
is always on the opposite side of the earth
longshore current
wave refraction occurs when waves approach the shore at an angle. waves at the shore
obliquely can cause a longshore current.
longshore drift
swash causes sand obliquely up the beach, whereas backwash carries it straight downslope. so
sand gains follow a sawtooth patter, yielding longshore drift.
se level rise
rise is estimated to be about 3.2 mm per year
atmospheric composition
nitrogen 78%
oxygen 21%
argon .9%
CO2 .04%
atmospheric aerosols
tiny solid or liquid particles that can remain suspended in the air.
inorganic aerosols
mineral dust, salts, sulfates
organic aerosols
pollen, bacteria, molds, viruses
atmospheric pressure
atmospheric pressure and air density decrease with increasing elevation.
what is a cloud?
collections of countless water droplets and/or tiny crystals suspended in the atmosphere.
clouds....
