The greenhouse effect is the natural warming of Earth's lower atmosphere and surface.

Explanation:

The idea of climate and temperature around the Earth begins with the sun. Approximately 30% of the sunlight reflects back to the cloud and ice from the surface.

The basic rise of the greenhouse effect is when the sun radiates around the earth.The greenhouse effect is the natural warming of Earth's lower atmosphere and surface. The 30% reflects back where the rest of the energy of the sun is collected by greenhouse effect and radiated to the surface again.

The radiation as well as the absorption of the heat is beneficial to the lower atmosphere as well as the surface as no other foundation can be reflected and radiated by the greenhouse effect.
