Insolation & Temperature


Methods of Heat Energy Transfer (Movement)

Preliminary Questions
  • radiation
  • heat is emitted from a body
  • radiant energy flows through air
    • short wave length (intense rays)
    • long wave length (much less intense)
  • conduction
  • heat movement from one molecule to another
    • e.g. hot fire iron warming hand
    • also cold water cooling the air (creating fog)

  • touching objects seek equilibrium
  • convection

    • heat is transferred from one point to another
    • molecules move away from heat source (expansion)
    • vertical movement of heat
      • e.g. afternoon thunderstorms
    • "advection" - horizontal heat transfer
      • e.g. advection fog
