beacuase part of it reaches the earth the rest is reflected back ;)
When Earths surface is heated it radiates some of the energy back into the atmosphere as "Infrared Radiation."
The higher the latitude the greater the thickness of atmosphere through which the sun's radiation has to pass, hence the lese energy reaching the ground.
due to volcanics effects and movement of earth which affect the earth surface
It is called geothermal energy.
the greenhouse effect!
the greenhouse
epicenter
Absorbed
The sun & the Earth's core.
They absorb radiant energy emitted by Earths surface
conduction
Because of the heat and light
