Answer: It is a process by which greenhouse gases allow the sun’s light to penetrate the atmosphere but stop the heat from escaping.
Explanation:
Greenhouse effect is the natural heating of the Earth's surface due to the fact that the sunligth waves may penetrate the atmosphere and reach the solid surface, but when the sunlight waves return after reaching the solid surface, process that changes the wavelength of the sunlight, they cannot penetrate the greenhouse gases and so the heat is kept inside the atmosphere with the consequent increase of temperature.
