Finite = Non renewable / limited / will run out (Oil,Coal, Gas)

Renewable = Endless / will not run out (Wood, Rubber, Wool)

Potable water = Safe to drink

Pure water = H2O only

Purficication

• Leave the water for the insoluble sediment particles to drop to the bottom (Sedementation)
• Filter through gravel to remove insoluble particles.
• Filter through sand to remove smaller insoluble particles.
• Pass through filter paper and funner to remove smallest insoluble particles.
• Chlorine tablets kill harmful bacteria. (Chlorination)

Desalination = Remove salt from water

Distilalation

• Boil water in solute in…
