What are the useful applications of greenhouse effect?

Explanation

The name .greenhouse effect. comes from the fact that this effect is to grow green plants in small houses made of glass walls and glass roofs which are called greenhouses. The glass walls and glass roof of a greenhouse allow the sun.s heat rays to go in freely but do not allow the heat rays reflected by the soil, plants and other things in the greenhouse to go out. In this way, more and more of sun.s heat rays are trapped inside the greenhouse and the temperature rises in it. So, even without an internal supply of heat, the temperature inside a greenhouse becomes higher than that of outside. This heat is beneficial for the growth of plants inside the greenhouse (when the outside temperature is very low during winter season). Thus, greenhouse acts as a heat trap.
