4. write about greenhouse gases deforestation and burning of fossil fuels.
Answers
Answer:
Green house gases:
these are the gases that may or may not be harmful for us directly but it's harmful indirectly.
these gas absorb most of the heat created my sunlight, and these gases doesn't allow those heat to escape earth
therefore all the heat get filled and filled and cause global warming
Deforestation:
cutting off trees randomly and clearing of the forest
burning of fossil fuels:
Fossils fuels, like diesel, petrol, coal...etc cause pollution, these fuel type aren't even reusable
Answer:
Carbon dioxide (CO2): Carbon dioxide enters the atmosphere through burning fossil fuels (coal, natural gas, and oil), solid waste, trees and other biological materials, and also as a result of certain chemical reactions (e.g., manufacture of cement). Carbon dioxide is removed from the atmosphere (or "sequestered") when it is absorbed by plants as part of the biological carbon cycle.
Methane (CH4): Methane is emitted during the production and transport of coal, natural gas, and oil. Methane emissions also result from livestock and other agricultural practices, land use and by the decay of organic waste in municipal solid waste landfills.
Nitrous oxide (N2O): Nitrous oxide is emitted during agricultural, land use, industrial activities, combustion of fossil fuels and solid waste, as well as during treatment of wastewater.
Fluorinated gases: Hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride are synthetic, powerful greenhouse gases that are emitted from a variety of industrial processes. Fluorinated gases are sometimes used as substitutes for stratospheric ozone-depleting substances (e.g., chlorofluorocarbons, hydrochlorofluorocarbons, and halons). These gases are typically emitted in smaller quantities, but because they are potent greenhouse gases, they are sometimes referred to as High Global Warming Potential gases
