water cycle

• 1. Evaporation — liquid to gas by energy from sun.
  2. Condensation — water vapour cools and gas turns to liquid (clouds)
  3. Transport — water in clouds blown to other areas by strong winds.
  4. Precipitation — rain, hail, snow
  5. Surface run off — water run along surface of ground
  6. Infiltration — water absorbed into ground
  7. Transpiration — water vapour evaporises
• Thermal desalination is the process of removing salt from seawater by heating it to a high temperature.

  • Expensive

  • Fossil fuels
• Reverse osmosis is a process that removes dissolved solutes from a solution by forcing the solvent through a semipermeable membrane.
