Earth Space Science Flashcards
biosphere
portion of the earth in which all known life forms exist
lithosphere
rocky outer part of earth
gases in the atmosphere
oxygen
nitrgoen
carbon dioxide
argon
why is the atmosphere important
contains gases vital to life
protective - filters out harmful gases
evaporation
the porcess of a liquid changing into a gas due to an increase intemp
precipitation
process of water falls to the earths surface
percolation
slow movement in water through soil
transpiration
evaporation of water from plants leaves
how does co2 get into the ocean
decomposing marine life or deep oceans
how does co2 be harmful to ocean
acidic
detritus
decomposing plants and animals
6 reservoirs of carbon
soils surface ocean deep ocean marine life plants animals
where is carbon found in living organisms
molecules in body
Dna
protein
fats
how does the process of feeding transfer carbon atoms
consumers eat plants
some glucose stored in body for growth
role of decomposers
consume dead plants and return co2 to atmosphere by respiration
decomposer example
bacteria or fungi
detritus feeder
break down dead matter return to ground as waste
detritus feeder example
maggots
2 processes that add co2 to air
respiration
combustion
carbon source
anythign that releases co2 into the atmosphere
carbon sink
anything that absorbs and holds co2
example of sink
limestone
rocks
fossils
example of source
fires
exhaust gases
carbon cycle
carbon enters from resp or burning
plants absorb co2 for photosynthesis and release oxygen
animals eat plants and co2 is exhaled through resp
decomposers return co2 to at
