earth systems and biochemical cycles
| Question | Answer |
|---|---|
| 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 |
