  • Radiation is
    Transfer of energy through electromagnetic waves.
  • What color of visible light has the longest wavelength?
    Red
  • How does the Sun's heat energy heat the Earth?
    Radiation through electromagnetic waves.
  • Which has the largest wavelengths?
    Radio Waves
  • Conduction is
    Transfer by direct contact of molecules.
  • Sea Breeze...
    Wind that blows from the sea to the land during the day.
  • Why is the sky blue?
    Due to scattering of shorter wavelengths of visible light
  • What is the Greenhouse Effect?
    Gasses trap heat in the air keeping the Earth at a comfortable temperature.
  • What form of heat transfer is shown?
    Convection
  • What is a Convection Current?
    Warm air rising because its less dense, once it becomes cooler it sinks because its more dense.
  • What form of heat transfer is shown?
    Conduction
  • What form of heat transfer is shown?
    Radiation
  • Which has the shortest wavelengths?
    Gamma Rays
  • Global Winds...
    Winds that blow over long distances.
  • Land Breeze...
    Wind that blows from the land to the sea at night.
  • Convection is
    Transfer of energy due to density differences (high pressure to low pressure)
