ch 3 Flashcards
geosphere
solid part of earth made of rock as well as soil and loose rocks on earth surface
hydrosphere
makes up all the water on or near the earth surface
crust
thin layer composed almost entirely of light elements
mantle
the layer beneath the crust makes up 68 percent of mass
core
innermost layer
lithosphere
outer layer
asthenosphere
layer beneath lithosphere
techtonic plate
parts of lithosphere
chemical weathering
wears down rocks
erosion
transports the materials else wear
atmosphere
mix of gases surrounding earth
troposphere
the atmosphere layer near surface
stratosphere
above troposphere
ozone
molecule made up of 3 oxygen atoms
radiation
transfer of energy as electro magnetic waves
conduction
transfer energy in form of heat from warm to cool
convection
the transfer of energy that takes place when variation in temp move the matter making up air
green house affect
the trapping of the sun’s warmth in a planet’s lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet’s surface.
water cycle
the continuous movement of water within the Earth and atmosphere
evaporation
Evaporation happens when a liquid turns into a gas
condencation
water which collects as droplets on a cold surface when humid air is in contact with it.
precipitation
the action or process of precipitating a substance from a solution.
salinity
The term “salinity” refers to the concentrations of salts in water or soils. Salinity can take three forms, classified by their causes: primary salinity
fresh water
Fresh water or freshwater is any naturally occurring liquid/solid water containing low concentrations of dissolved salts and other total dissolved solids.
biosphere
the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms.
