Earths atmosphere is warmed by the greenhouse effect because heat radiation from earth surface is what by gases in the atmosphere

Green House Effect is the Technique in Botanical science that is use in the garden to capture more light and decreases that amount of light that bounces back to the atmosphere. The light will be trapped inside a glass cage and be use by the plants in their photosynthesis. So if the earths will be affected by this technique, the gases from the atmosphere are mostly the reason that the light that is passes through it will not be the same that bounces back to the outer space. In a clearer way of explaining, the heat is trapped inside the earths atmosphere and may cause global warming inside of it.
