The natural process of trapping and releasing heat by greenhouse gases in the air is called the Greenhouse effect. Without this, the Earth would either be extremely cold or extremely hot, and life here would be impossible. The greenhouse effect is something that happens naturally.
Introduction to Greenhouse Gases and their Emissions
The gases in our atmosphere, which absorb the heat energy from the sun and reflect it towards the earth, are called Greenhouse Gases. These gases help in keeping the earth warm. The Greenhouse Gases should be in balance, excess of which may be harmful and make the earth warmer than the needed.
The greenhouse effect is the trapping of radiation in the lower atmosphere warming the temperature of the Earth. The natural greenhouse effect is essential for sustaining life on Earth. The effect of greenhouse gases in the atmosphere is intensified due to the emission of these harmful gases in the atmosphere by mankind. This warms the temperature of the earth leading to Global warming.
Greenhouse Gases
The Greenhouse Gases mainly absorb a part of the infrared radiation from the sunlight and help in balancing the temperature of the earth. The Greenhouse Gases include Water Vapour, Methane, Carbon Dioxide, Nitrous Oxide, Ozone, Chlorofluorocarbon, and Hydrofluorocarbon.
Greenhouse Gases and their Emissions
The motor vehicles on the road emit the most proportion of the Greenhouse Gases. These Gases are Carbon Dioxide and also Methane and Nitrous Oxide. The electricity generation now a day shares the second most shares in Greenhouse Gas emissions. It is because if the generation of electricity through the burning of fossil fuels like coal and petroleum products. Chimney of Factory and the house also produce Greenhouse Gases, mainly Carbon Dioxide. Apart from these, Refrigerator and Air Conditioner also generate Greenhouse Gases.
Here are some of the major causes of Greenhouse effect:
Natural Causes:
- Some naturally present elements on Earth produce greenhouse gases such as carbon dioxide that can be found in oceans, methane that is produced by decaying of plants due to natural forest fires and nitrogen oxide that is present in soil and water in small amounts. Only fluorinated gases are produced by humans and are not present in nature.
- Water Vapour is also crucial in greenhouse effect. Water vapour absorbs thermal energy, mostly when the humidity rises in the air. This raises the temperature in the atmosphere.
- Animals breathe oxygen from the atmosphere and release carbon dioxide and methane gases. It is also one of the natural causes of greenhouse effect.
Manmade Causes:
- Burning of fossil fuels such as oil and coal is one of the greatest contributors of the greenhouse effect. Burning fossil fuels emits carbon dioxide in the atmosphere which is the cause of greenhouse effect. Further, the atmosphere is polluted by the release of methane gas from Earth when the gas, coal mines or oil wells are dug.
- Deforestation is another major cause of greenhouse effect. Trees help in reducing the carbon dioxide and producing oxygen. By clearing away forests and trees the carbon dioxide in the atmosphere continues to rise.
- Artificial nitrogen is used for the fertilization of crops, which is released as nitrogen oxide in the atmosphere. Nitrogen oxide in the atmosphere increases greenhouse effect.
- Industrial gas is released in to the atmosphere at very high rate across the world. Industrial gases include gases such as methane, carbon dioxide and fluorine gas.
- Farm animals such as goats, pigs, cows also contribute to greenhouse gases. Methane is produced in their stomach when they digest their food and is released through their manure into the atmosphere. Clearing away forest to expand farmland for raising farm animals further elevates the emission of greenhouse gases.
Conclusion
Currently, the earth is suffering from the excess of Greenhouse Gases. We need to stop it as soon as possible else we would be forced to live in hell.
Greenhouse Gases and their Emissions Essay FAQs
What are the greenhouse gases and their emissions?
Greenhouse gases include carbon dioxide (CO2), methane (CH4), and water vapor (H2O). They trap heat in the Earth's atmosphere, leading to global warming.
What is greenhouse effect in 150 words?
The greenhouse effect is when certain gases in the atmosphere trap heat from the sun, keeping the Earth warm. It's essential, but too much of it can cause climate change.
What are greenhouse gas emissions and why are they important?
Greenhouse gas emissions are the release of gases like CO2 into the air, mainly from human activities. They're crucial because they contribute to global warming and climate change.
What is the greenhouse effect essay?
The greenhouse effect essay should explain how certain gases trap heat, leading to a warmer planet and the impact of this on the environment and weather patterns.
What is greenhouse effect 10 points?
The greenhouse effect in 10 points: (1) Certain gases trap heat, (2) It warms the Earth, (3) Human activities release more of these gases, (4) This leads to global warming, (5) Rising temperatures affect weather, (6) Melting ice and rising sea levels, (7) Changes in ecosystems, (8) Impact on agriculture, (9) Need for reducing emissions, (10) Addressing climate change.
Is greenhouse effect good or bad?
The greenhouse effect can be both good and bad. It's good because it keeps our planet warm enough for life. However, too much of it due to increased greenhouse gas emissions is bad, leading to global warming and climate change.
