Where is water stored on Earth? Flashcards
what are the four water stores?
lithosphere, hydrosphere, cryosphere and atmosphere
what is the lithosphere?
the solid outer crust and upper mantle
what is the hydrosphere?
water on the surface of the planet
what is the the atmosphere?
the layer of gases surrounding the planet
where is the lithosphere found?
in oceanic It is stored within the rock structure made of continental crust and rocks, minerals, and clays as groundwater
what does the hydrosphere include?
oceans, seas, rivers, streams, lakes and ponds
What’s the cryosphere?
frozen areas on the planet
what does the cryosphere include?
glaciers and ice sheets as well as frozen sections of oceans, e.g. antarctic
what does the atmosphere consist of?
water storage in clouds, all layers layers of atmosphere, clean air, microscopic particles of water vapour are carried
approx. how much of global water store is hydrosphere?
96.5%
approx. how much of global water store is atmosphere?
0.001%
approx. how much of global water store is cryosphere?
1.7%
approx. how much of global water store is lithosphere?
1.7%
What has limited change in volume over short-term?
hydrosphere
considering longer time scales, what will decrease and why?
volume of ocean water as more is contained in the cryosphere
