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: -The greenhouse effect helps trap heat from the sun, which keeps the temperature on earth comfortable. But people’s activities are increasing the amount of heat-trapping greenhouse gases in the atmosphere, causing the earth to warm up.

Detailed explanation-3: -Greenhouse gases at certain levels do not harm the environment. But when the concentration of these gases increases, it traps enormous heat on the earth’s surface which is known as the ‘greenhouse effect’. This leads to an increase in the earth’s temperature. This phenomenon is called ‘global warming’.

Detailed explanation-4: -The excessive burning of fossil fuels such as petrol, coal, etc. have resulted in an increase in the number of greenhouse gases in the atmosphere resulting in a phenomenon known as Global Warming. This is an increase in the ambient temperature of Earth which will negatively affect life on Earth.
