eartn science 3
earth: active planet
energy and matter distributed over spheres
lithosphere: solid rock and soil component of crust & upper mantle
hydrosphere: the water on, in & around the Earth
atmosphere: gases surrounding Earth
the biosphere: living things on Earth
most energy from sun, volcanoes/quakes show energy in earth
landscapes result of the opposition of forces: exogenous and endogenous
exo: sun heat earth, moves water cycle, sudden changes temp, wind, rain, shape land
endo: internal heat, volcanoes, quakes, lith plate move, form mountain ranges
earth energy: geothermal
endogenous heat(heat from inside earth)
fuled byfossil heat
nuclear fission on radioactive mats, generates heat
+1C° every 30m(geothermal depth)
heat and pressur rise slower the deeper
5000C° at center
heat from inside into atmosphere-->heat flux(0.075Watt/m^2) higher where volcanic activity
obtain info on earth interior
direct method(drilling and samples)
indirect(seismic waves)
geosphere layers
lithosphere
asthenosphere
mesosphere
outer core
inner core
metal sphere, iron and nikel, solid
core
core convection

mats: semiliquid or liquid
solid, plastic
mantle
mantle convection
mats in lower layers of mantle rise as warmer and therefore less dense, than upper mats
rocks:solid, plastic->magma
crust and uppermost mantle
mats:solid, rigid, brittle
crust
