17
Q

what is the hydrological cycle powered by

A

solar energy and gravity

18
Q

solar energy causes what

A

causes the evaporation from soil, plants oceans, lakes streams

19
Q

how are clouds made

A

warm air rises and lifts water into atmosphere

20
Q

what does gravity do

A

pulls it down as rain or snow

21
Q

fresh sources

A

ground water and surface water

22
Q

water table

A

upper surface of ground water
more rain = high water table

23
Q

Acid deposition

A

Acid water getting evaporated = acid rain

24
Q

Water as a solvent:

A

Dissolves nutrients ; nitrates and phosphates
Cycles CO2 and O2 in water
Essential for photo synthesis and cellular respiration
