Distribution Of Stores In The Water Cycle

Question 1

Atmosphere

Answer 1

Water molecule is held in the atmosphere for 9 days

Smallest store of water

Water vapour

Absorbs and reflects incoming radiation

Warm air holds more water vapour than cold air

Increase in water vapour = increase in atmospheric temperatures = more evaporation = more water vapour = more cloud and precipitation = more evaporation and water vapour held in the atmosphere = more long wave radiation is absorbed = warmer temperatures.

Question 2

Oceans

Answer 2

Five oceans and several seas that cover 72% of the earths surface

Largest cover is the Pacific Ocean

Oceans contain 97%v of global water

Question 3

terrestrial water

Answer 3

Amazons main discharge of water is rivers

Canada and Finland have the largest number of lakes

Wetlands are present on every continent except Antarctica

Includes groundwater, soil water and biological water

Question 4

Cryosphere

Answer 4

Sea ice, ice caps( Himalayas, Rockies,Andes, southern alps of New Zealand), ice sheets ( Antartica, Greenland), alpine glaciers and permafrost

High altitude and high latitude areas

Question 5

Water movement

Answer 5

Water moves through stores through processes such as precipitation, evaporation, overland flow and groundwater flow
