water stores Flashcards
factors affecting change in the magnitude of water stores?
- climate change
- human acitivity
- vegetation
- climate-temperature
why does soil moisture have the shortest residence time?
- quickly percolated back into bedrock
- transpired by plants
- transferred into rivers
- evaporated
what are the 3 states of water?
soild - ice
liquid - water
gas - water vapour
oceanic water
- 5 oceanic bodies of water covering approx 72% of earths surface
- pacific ocean is largest
cryospheric water
composed of sea, ice caps, ice sheets, alpine glaciers
mainly in high altitude and high latitude areas
terrestrial water
rivers and lakes
wetlands
groundwater, soil and biological water
atmospheric water
the most common form is water vapor
important as it absorbs and reflects solar radiation

runoff
condensation
what are the inputs of the water cycle?
rain
what are the outputs of the water cycle?
evaporation

hydrosphere and biosphere ]
hydrosphere provides water for the biosphere to function and grow, animals drink the water in order to survive
interaction provides humans with oxygen to be able to breath
