Nimbus
|
rain
|
|
|
cumulus
|
pile
individual cloud masses that often have flat passes |
|
|
how do clouds form?
|
by condensation at the dew point temp around a dust particle
|
|
|
cold air is more dense and has higer pressure
warm air is less dense and has lower pressure |
same
|
|
|
why is water the universal solvent?
|
because so many substances are soluble in water
|
|
|
acid or base?
|
use and indicator to test it
litmus paper-blue litmus-red in an acid red litmus-blue in base ph paper- how acidic a solution is phenolphtalen-colorless remains colorless in acid-turns bright pink in base |
|
|
stratus
|
layer
|
|
|
cirrus
|
means curl of hair
|
|
|
equinox-equal day-vertical rays strike equator
how many hours is an equinox? |
12 hrs
|
|
|
solstice
|

|
|
|
trophoshere
|
where weather happens
bottom of layer,where we live,temp decreases with and increase of altitude |
|
|
stratosphere
|
absorbs ultraviolet radiation
temp is constant to 20 km , then increases |
|
|
thermosphere
|
4th layer, extends outward from the mesosphere
only contains a fraction of the atmospheres mass no well defined upper limit very little air |
|
|
mesosphere
|
3rd layer
temp decreases with height at 80 km temp approaches -90 degrees C coldest temp in atmosphe |
|
|
composition of air
78% N2 ( nitrogen) 21% O2( oxygen) 4% water |
21% O
|
|
|
greenhouse effect?
|
heat trapped in atmosphere by co2 and h2o-increases temp of Earth
|
|
|
spring tides
|
2x a month, high high tides and lower low tides
|
|
|
neap tides
|
2x a month, have lower high tides and hier low tides
|
|
|
tides
|
daily change in the elevation of the ocean surface
|
|
|
what causes tides?
|
moons gravitational pull
|
|
|
deep zone
|
80% of all ocean life, sunlight never reaches here temp is just above freezing
|
|
|
transition zone
|
thermocline and pynocline are here
|
|
|
ocean basin floor
|
abysssal plain with seamounts and abyssal hills
|
|
|
continental slope
|
steeper structure that marks the boundary between the continental and oceanic crust
|
|
|
continental shelf
|
gently sloping submerged surface extending from the shoreline toward the ocean basin floor
|
|
|
continental margins
|
shelf+ slope+ rise
|
|
|
5 ocean basins
|
atlantic,pacific,indian,southern,asian
|
|
|
surrface currents
|
masses of ocean water that flows from one pice to another pushing water deep, starts to move it
(coriolis effect) |
|
|
waves
|
energy from the wind, transverse circular motion
|
|
|
pynocline
|
density affected by salinity and temp
|
|
|
thermocline
|
rapid change of temp with depth
|
|
|
where are high salinities found?
|
where evaporation rates are hight ex subtropical regions
|
|
|
the process that removes large amounts of fresh water to sea waay and increases salinity include: e
|
evaporation and formation of sea ice
|
|
|
high evaporation=
|
high salinity
|
|
|
what process ads large amounts of fresh water to sea water and decreases salinity ?p
|
percipitation, runoff from land, ice bergs and sea ice melting
|
