describe the troposphere
layer of atmospheric gases o-10km fr earths surface. temp decreasesw/ increasing distance from earths surfacein of -60.contains 80% of gas by mass.
only layer with temp range ang oxygenconcentration that can support living things.where most weather occurs
describe the stratosphere
above trop.increases w/ disatance fr earths surfacemost ozone gas.ozone layer
describe inversion
a reversal of normaltemp patterns seen in the trop
describe the thermosphere
hottest furthest fr earth.-100 to 1500v.little gas
describe the lithosphere
home 2 micro organisms plants, animals and humans.warmed by incoming nrg fr sun and molten material in mantle
describe the hyrosphere
97%salt 3%fresh
describe climate change
a change that occurs in the climate of a region over tme min of 30 years
what is the difference between anecdotal and scientific evidence
a=evidence that relies on reports fr ppl about certain events and their interpretation on them.not tested 4 bias.
sc=evidece collected in a manner that insures amap it is unbiased reflects general situations rather than particular events. collected by trained scientists
what is adaptation
any change in the structure or functioning of an organism that makes it more suited to its environment
what is thermal energy
amount of nrg possesed by a substance of virtue of the kinetic nrg of its molecules or atoms
what is solar nrg
nrg fr sun. generated by hydrogen-hydrogen nuclear fusion
how does cloud cover influence the amount of solar radiation that reaches the earths surface
bcause clouds reflect incoming solar radiation back to space and absorb kinetic nrg that is emmited by earths surface
what is the electro magnetic spectrum
measurment of wavelengths fr the sun.
what determines the albedo of a material
the amount of solar nrg that is reflected versus the amount absorbed.the albedo is the percent of solar radiation that is reflected. light colored surfaces lik snow reflect more
explain earths net radiation budget
the diff btween the amount of incoming and outgoing radiationreemitted fr earths surface and atmosphere
when does the north pole recieve the highest insolation
during our summer
what is the angles of inclination
the degree thatearths poles r tilted frthe straightof the plane of its orbit
what is the angle of incidence
the anglebtween a ray falling on a surface and t6he line of perpendicular to that surface
describe insolation
tha amount of solar nrg recievedby a region of earths surface
transfer of thermal nrg through direct contact btween the particles of a substanmce, w/o moving particles 2 a new place.solids
transfer of thermal nrg through movment of particles fr one place 2 another fluids
coriolis effect
deflection of an object fr a straight line path by the rotation of the earth. causes movin air or wind 2 turn right in the northern hemisphere and left in the southern hem
trade winds
regions near equator wind that blow steadily se and se. caused by coriolis effect
jet streams
band of fast movin air in strato
specific heat capacity
amount of nrg required 2 raise the temp of a 1g of substance by 1 degree
heat of vapourization
amount of nrg absorbed when 1 mol of a sub changes fr vapour 2 gas w/o change in temp
heat of fusion
amout of nrg absorbed when 1 mol of substance changes fr solid 2 liquid w/o change in temp
open sytem
a system that exchangeg both matter ang nrg w its surroundings
closed system
xchange nrg but not matter
4 main greenhouse gases
water vapr, co2, methane, n2o
fossil fuels
carbon based fuels formed fr dead organisms
caebon source
any process the releases co2 to the atmospherelike burning fossil fuels
carbon sink
removing co2 fr atmosphere like photosynthesis
enhanced greenhouse effect
the change in earths net radiation budget, by increase of human gen greenhouse gas
