WATER CYCLE

WATER  CYCLE

A key process in the hydrosphere is known as the water cycle where by water evaporation rain on the mowntains and flows and back to sea.


The water cycle contains many little quirks and paths such as the sublimation of water on land and the storage of water on land of water in underground aquifers.


Underground aquifers are so huge and abundant that they contain enough water for hundreds of years.

Ice sheets, covering large portions of antarctica and greenland make up about 77%of the global total of freshwater . Due to global warming many of these sheets are melting causing the word,s ocean levels to slowly rise.

EVAPORATION

Evaporation is the process where a liquid in this case, water chan ges from its liguid water becomes water vapor . 

During the water cycle some of the water in the oceand and fresh water bodies shuch as lakes and rivers is warmed by the sun and evaporates. on ture is the primary factor. 


PRECIPICATION


When the temperature and atmospheric pressure are right the small droplets of water in clouds from larger droplets and precipitation on occurs .The rain drops fall to earth.


TRANSPIRATION


One final process is important in the water cycle . as plants absorbs water from the soil the water moves from the roots throught the stems to the leaves. once the water reaches the leaves someof it evaporates from the leaves adding to the amount of water vapor in the air.
