All living matter

Question 6

Oceanic water

Answer 6

Covers 72% of earth
PH has dropped from 8.25 to 8.14 in 250yrs

Question 7

Water covers soil all year

Question 11

Groundwater

Answer 11

Water collected underground in pore soaces

Question 12

Soil water

Answer 12

Soil moisture is key in controlling exchange of water and heat energy

Question 13

Biological water

Answer 13

Water stored in all biomass

Question 14

Evaporation

Answer 14

Energy from solar radiation hits water and turns to gas

Question 15

Condensation

Answer 15

Air cools and can hold less water vapour

Question 16

Melting

Answer 16

Heat applied to ice and changes to water

Question 17

Freezing

Answer 17

Cold temperatures cause liquid to turn to ice

Question 18

Sublimation

Answer 18

Water changes from solid to gas

Question 19

Deposition

Answer 19

Water changes to ice without becoming liquid
