Identify what happens to light in this model of the greenhouse effect.

Answer 1

The greenhouse effect is a natural process which increases the temperature of the Earth. The greenhouse effect is caused by the absorption by the surface of the Earth and re-absorption by the atmosphere of the greenhouse gases (CH₄, CO₂, NO, CFCs ) in the environment.

This is caused when solar radiation reaches Earth- some of the energy is absorbed by the land and water while the rest of the energy is reflected back into space. Now the absorbed heat radiate from earths surface is trapped by the greenhouse gases in the atmosphere which causes the warming of the Earth. But due to the increase in greenhouse gases extra heat is absorbed which leads to Global warming.

Thus, marked options in the box are correct.
