Solar (Radiation)

Energy

Radiation = the transfer of energy though space by electromagnetic waves.

Now… what's different about the temperatures?When the sun is down, we have cooler LAND and warmer WATER.

Heat can be transferred in 3 ways…Conduction, Radiation, Convection

The sun provides heat energy called RADIATION and it creates CONVECTION Currents in our atmosphere.

Sun’s Rays“Uneven Heating of the Earth due to

the curvature of Earth”

• Larger Angle = More intense heat (hotter)

• Acute Angle = less intense heat (cooler)
