Water Convection Currents Air Processes Controlling Organisms Heating

Front Processes controlling organisms heating up and cooling down
Back
  • Exothermic chemical reactions
  • Latent heat of evaporation (object cools as water evaporates from surface)
  • Radiation (transmission of EM waves to and from air, water or ground
    • Convection (heating/cooling by currents of air or water, warm air/water rises and cooler sinks, setting up convection currents around organism
    • Conduction (heating due to collision of molecules, ground/water good conductors but air isnt)
