earth systems and biochemical cycles

QuestionAnswer
earth is considered a ____________ system in terms of matter? closed
earths four spheres include? atmosphere,lithosphere/geosphere,hydrosphere, and biosphere
this sphere includes all of the land such as rocks, minerals, mountains, and mantle. it is the- lithosphere/geosphere
this sphere includes all of water such as the oceans, clouds, and rivers. it is the- hydrosphere
this sphere includes all of air such as nitrogen,oxygen, and carbon dioxide. it is the- atmosphere
this sphere includes all life such as plants, animals, and humans. it is the- biosphere
the processes that move matter and energy from one sphere to another is called- sphere interactions
the biosphere may interact with the following spheres- hydrosphere, lithosphere, and atmosphere
the water cycle includes water in- clouds,oceans, and in bodies
a change in one earth system such as increasing co2 has what affect on other sphere? good affect
trees/plants biosphere
soil lithosphere/geosphere
seeds/spores biosphere
runoff hydrosphere
pioneer plants biosphere
streams/rivers hydrosphere
fumes atmosphere
animals/people biosphere
trees and plants burn in a fire. the plant debris that did not blow away becomes the new soil that provides nutrients to pioneer plants biosphere>geosphere/lithosphere>biosphere
because soil moisture is extremely low due to the fire, seeds and spores cannotgerminate. a decrease in vegitation and roots to hold the soil in place may result in increased erodabilility of the soil geosphere/lithosphere>biosphere>geosphere/lithosphere
runoff increases erosion. which changes the turbidity,temperature,and pH of the streams and rivers hydrosphere>geosphere/lithosphere>hydrosphere
burning trees give off smoke and noxious fumes that may coat the lungs of animals and people, affecting their ability to breathe biosphere>atmosphere>biosphere
list 4 examples of how humans directly affect the geosphere .gardner pulls grass from coast .miners dig up fossil fuels .farmers plant crops in fertile soil .construction workers dig foundations
