Explanation:
Detailed explanation-1: -The greenhouse effect: some of the infrared radiation from the Sun passes through the atmosphere, but most is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds. The effect of this is to warm the Earth’s surface and the lower atmosphere.
Detailed explanation-2: -Higher up, in the stratosphere, the ozone layer absorbs solar ultra-violet radiation and affects how much of the Sun’s heat is radiated back into space.
Detailed explanation-3: -Greenhouse gases repeatedly absorb and re-radiate infrared radiation (heat). Energy radiated from Earth’s surface as heat, or infrared radiation, is absorbed and re-radiated by greenhouse gases, impeding loss of heat from our atmosphere to space.
