Earth's heat budget
Earth's heat budget
Balance between energy coming in & energy leaving Earth
Earth's primary energy source
Earth's primary energy source
The sun
Components of solar radiation
Components of solar radiation
Visible light, UV radiation & infrared radiation
How dark surfaces respond to solar energy
How dark surfaces respond to solar energy
Absorb more energy, convert to heat, warm up quickly
How light surfaces respond to solar energy
How light surfaces respond to solar energy
Reflect more energy back to space, remain cooler
Conduction
Conduction
Heat transfer through solid materials by direct contact
Convection
Convection
Heat moves through fluids like air & water
Radiation (in heat budget)
Radiation (in heat budget)
Earth emits infrared radiation back to space
Movement of warm air in convection
Movement of warm air in convection
Rises (whilst cooler air sinks)
What balances to maintain stable climate
What balances to maintain stable climate
Incoming solar energy & outgoing infrared radiation
Result when incoming = outgoing energy
Result when incoming = outgoing energy
Earth's average temperature remains relatively stable
Role of atmosphere & clouds in heat budget
Role of atmosphere & clouds in heat budget
Regulate temperature by absorbing/trapping radiation
