GENERAL KNOWLEDGE

Detailed explanation-1: -Greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), ozone (O3), and fluorinated gases. Greenhouse gases allow the sun’s light to shine onto Earth’s surface, and then the gases, such as ozone, trap the heat that reflects back from the surface inside Earth’s atmosphere.

Detailed explanation-2: -Greenhouse gases have different chemical properties and are removed from the atmosphere, over time, by different processes. Carbon dioxide, for example, is absorbed by so-called carbon sinks such as forests, soil, and the ocean. Fluorinated gases are destroyed only by sunlight in the far upper atmosphere.

Detailed explanation-3: -Greenhouse gases trap heat in the atmosphere, in a process called the “greenhouse effect.”1 But how do these molecules actually warm our planet? We’ll start our exploration of greenhouse gases with a single carbon dioxide (CO2) molecule.
