Heat Transfer Radiation Convection Conduction

Radiation transfer of energy by electromagnetic

waves. Can carry energy through space (does

not need matter)

Solar radiation- EM spectrum

Heat Imbalance

Poles & equator receive the same amount of solar energy

Equator: direct, high angle (90 degrees), high intensity solar energy

Poles: indirect, low angle (30 degrees) solar energy › Solar energy spread out

over a larger area

Heat Imbalance

Intense heat at the equator is distributed around the world› Movement of air & water

Heat imbalance wind (cause) (effect)

Coriolis Effect

Caused by rotation of Earth

Causes water & air to curve

N Hemisphere clockwise

Energy Transfer Light Energy Chemical Energy

› Photosynthesis (by plants)› Chemical energy

Stored energy Sugar

ENERGY Transfer

Chemical energy Mechanical & Heat energy

› Respiration (every cell does this)› Mechanical energy: movement

Greenhouse Effect & Global Warming

Greenhouse Effect› Natural warming › Atmosphere traps the heat (blanket)› No greenhouse effect on Earth it would

be too cold for life (all water frozen) Global Warming

› Increasing concentrations of CO2 (GHG, traps in more heat)

› Increasing temperatures

Vocab Absorb

› Waves taken in› Changed into heat

Reflect› Waves bounce off an object› Are NOT changed into heat
