<Li> water abstraction from rivers </Li> <P> The water cycle is powered from solar energy . 86% of the global evaporation occurs from the oceans, reducing their temperature by evaporative cooling . Without the cooling, the effect of evaporation on the greenhouse effect would lead to a much higher surface temperature of 67 ° C (153 ° F), and a warmer planet . </P> <P> Aquifer drawdown or overdrafting and the pumping of fossil water increases the total amount of water in the hydrosphere, and has been postulated to be a contributor to sea - level rise . </P> <P> While the water cycle is itself a biogeochemical cycle, flow of water over and beneath the Earth is a key component of the cycling of other biogeochemicals . Runoff is responsible for almost all of the transport of eroded sediment and phosphorus from land to waterbodies . The salinity of the oceans is derived from erosion and transport of dissolved salts from the land . Cultural eutrophication of lakes is primarily due to phosphorus, applied in excess to agricultural fields in fertilizers, and then transported overland and down rivers . Both runoff and groundwater flow play significant roles in transporting nitrogen from the land to waterbodies . The dead zone at the outlet of the Mississippi River is a consequence of nitrates from fertilizer being carried off agricultural fields and funnelled down the river system to the Gulf of Mexico . Runoff also plays a part in the carbon cycle, again through the transport of eroded rock and soil . </P>
