Flashcards
GEO [#1] The Earth System
Cards in this deck (22)
- 1AlbedoThe ability of a surface to reflect light
- 2Back RadiationThe amount of radiation lost by Earth. Should be the same as the amount coming in
- 3Habitability of EarthEarth is not too hot or cold
Earth is protected from harmful solar radiation by its magnetic field
Earth has the right chemicals for life - 4Four SpheresGeosphere/Lithosphere
Hydrosphere
Atmosphere
Biosphere - 5Biogeochemical CyclesMatter moves in spheres by chemical reactions or phase changes
- 6GroundwaterWater that exists within Earth's crust
- 7Water CycleStored in atmosphere, lakes, rivers, oceans, groundwater and vegetation. Is transported by evaporation precipitation, runoff, infiltration and transpiration
- 8Carbon CycleStays in reservoirs before processes move it around. Can be in the atmosphere, vegetation, soils, surface of the ocean, deep ocean, and rocks and sediments
- 9Organic CompoundsProduced by living organisms, are carbons bonded to hydrogens like proteins, carbohydrates, fats and DNA
- 10Inorganic CompoundsAlso produced by living organisms but do not have carbons bonded to hydrogens. Include CO2 and CO
- 11Organic Carbon StorageStored in vegetation, soils, rocks and sediments
- 12Inorganic Carbon StorageStored in the atmosphere, surface of the ocean, the deep ocean and rocks and sediments
- 13FluxThe rate of exchange of carbon. Is measure in gigatons/year
- 14Small ReservoirsExchange all of their carbon in a few years
- 15Large ReservoirsTakes more than 1000 years to exchange all of the carbon
- 16How Carbon Exchange OccursBy decomposers, photosynthesis, lithification, ocean acidification, respiration, fossil fuel burning and deforestation
- 17BiomesAreas defined by the types of plants and animals present
- 18UpwellingBrings nutrients back up to the surface by winds that go in certain direction on the surface of the ocean water
- 19Residence TimeHow long a single atom of carbon stays in a reservoir
- 20Rock CycleDescribes how rock types turn into other rock types
- 21Nitrogen And Phopsphorous CyclesPhytoplankton extract nutrients from water and store them, they die and sink, slowly decay and release carbon into the water, moving the nutrients away from the surface
- 22VolcanoesMove from the geosphere to the atmosphere. Move water, carbon dioxide and sulfur dioxide
