Increasing Earth’s Thermosphere Temperature There are five major layers in our earth’s atmosphere, that is Troposphere, Stratosphere or Ionosphere, Mesosphere, Thermosphere, and last one is Exosphere from lowest to highest heights. There were recorded a highest temperature in our planet’s thermosphere compared to the past two decades, NASA reported. In this session we are going to discuss, the reason and impact of increasing Thermosphere temperature. Earth's Internal Structure Earth’s Thermosphere As we know that Earth’s thermosphere is the second highest layer of the atmosphere , which spreads out across 513 km. This layer is located between the  Mesosphere , which starts at around 85 km above earth’s surface, and the  Exosphere , which begins at around 600 km above the ground. There is outer space lies above the exosphere. How NASA Measures Thermosphere’s Temperature There is a presence of Carbon dioxide and Nitric oxide molecules in the Thermosphere , which releas...

Shifting Cultivation Shifting Cultivation is that agriculture, in which forest or bushes are cleared by fire and cultivated in it. When the fertility of the soil of that field ends, then leaving that place, farming is started again at a new place. It is also called 'slash and burn' or 'bush and fellow' agriculture. This type of agriculture is done in different regions of the world, which are known by different names. In this article, we will know about the shifting agriculture found in different parts of the world. The names are as follows – Layers of the Atmosphere Shifting Cultivation of India Jhoom Agriculture – Agriculture done by tribals in North Eastern states of India. Jara and Erka  – Agriculture done in South Indian state. Podu  – Shifting agriculture practiced in the regions of Andhra Pradesh. Kumari  – Agriculture called Kumari is agriculture done in the mountainous regions of the Western Ghats of Kerala. Vevar and Dahiyar  – This is agriculture done in...

Air Pollutant “Such substances or factors that directly or indirectly affect the quality of air or its definite proportion are called air pollutants .” When the quantity of these factors increases too much in the air, adverse effects start appearing on the living beings and humans. If we say in other words, "Those substances or gases which are responsible for air pollution are called Air Pollutant ." Directive Principles of State Policy : Article 36- 40 According to the World Health Organization (WHO), “Air pollution is a condition in which such substances accumulate in the external atmosphere, which become harmful to humans and their environment.” These substances collected in the atmosphere are called pollutants. In general terms, there are three differences between them. There are physical pollutants (heat, foul smell, radioactive radiation etc.), biological pollutants (pollen grains, micro-organisms and agricultural residues etc.) and chemical pollutants (insecticides, ch...

Energy Sources Energy can be an indicator of the economic progress of a country. In a country where the average per capita energy consumption is high, the standard of living of the citizens of that country is considered high. As the population of the country increases, the per capita energy consumption will also increase. Our country India is still far behind in terms of per capita average energy consumption. The reason for this is the availability of limited energy resources with India. India imports most of its requirements from abroad. If we have to move forward on the path of progressive progress, then we have to keep in mind the energy crisis as well and accordingly we have to run an awareness campaign among the general public. There can be many reasons for the cause of Energy Crisis . Ministries and Departments of Govt. of India : A Brief Outline We need energy not only for domestic, industrialization, transportation but also for agricultural works. There can be many causes of en...

GREEN HYDROGEN Green Hydrogen can also be defined as hydrogen. Hydrogen is the simplest and smallest element of the periodic table, which is found in abundance in nature. It is also found freely in nature. It can also be obtained by splitting water into its constituents, Hydrogen and Oxygen, by electrolysis. Hydrogen is a lightweight, storable, energy-intensive and highly reactive fuel. There is no direct emission of any air pollutant or greenhouse as a result of its combustion. In this way, we can say that Green Hydrogen is such a source of renewable energy, which along with meeting our future energy needs, it also gets rid of many types of pollution. Production of Green Hydrogen We get it through various processes like fossil fuel, biomass, water and natural gas. At present, about 3/4 of the total production of green hydrogen is being obtained from natural gas. Due to the cost of its production being very expensive, only a few plants have been established so far. We get it by the fol...

Carbon Footprint You must have often heard about global warming. This is a universal and widespread phenomenon, due to which the entire earth is being negatively affected. The sea level is rising rapidly, due to which the number of floods on the coast has increased. Carbon dioxide (CO 2 ) is one of the primary causes of global warming. It is a green house gas, which increases the heat of the atmosphere. Industrial units play a big role in increasing the amount of this greenhouse gas. Therefore, it is necessary that we protect our earth from rising temperature. Industrial units and corporate world need to take initiative for this. Along with this, through various organizations and voluntary organizations, wide awareness and awareness should be run in this direction. This awareness should also be increased among the children studying in schools and colleges, proper material should be included in their curriculum. E-learning and digital learning can play an important role in reducing carb...

Cigarette Smoking Cigarette smoking is a smoke. Tobacco and other mixed substances are filled inside the cigarette. When addicted to it, it is very harmful for the body’s organs, mainly the lungs. Lung cancer is caused by this, due to which a person can also die. A person exposed to harmful tobacco-containing smoke emitted by cigarette smoking is also affected. This is called passive smoking . According to a report, most of the youth who smoke at present want to quit it and in a year only one person out of every 10 people is successful in quitting it. Quitting addictive habits and addictions like smoking is not so easy, yet you should try. There are some alternatives available on the market to help you quit cigarette smoking, which may help you. But use them only according to the advice of the doctor. Some Important Shapes Formed as a Result of Weathering and Erosion Alternative of Cigarette Smoking Nicotine Patches and Gum Nicotine Patches Nicotine Gum Herbal Cigarettes Vaping Pongal ...

Science Science is a very wide field. There are various branches and sub-branches of science. It is mainly divided into two parts Natural Science and Social Science. Natural Science is again divided into two parts Physical Science and Biological Science, which are further divided into various branches and sub-branches. While various subjects of Arts Group have been kept under Social Science. Indian Classical Dance Form Different Branches of Science and Their Fields of Study  Animal Science or Zoology - Zoology: Detailed study of different types of living and dead animals Botany - Study of different types of plants and their activities. Paleontology -  Palaeobiology or Palaeontology: Study of different types of fossils (animals or plants). Paleobotany – Palaeobotany: Study of plant fossils. Palynology - Palynology: Study of different types of pollen grains. Genetics - Genetics: Study of genetic characteristics of organisms and their heredity. Ecology: Study of the environme...

Energy Crisis The situation arising out of lack of energy resources in a country is called Energy Crisis. Energy crisis can hinder the development of a country. There are various factors related to Energy Crisis. At present, due to Russia-Ukraine war, Russia-Europe tension and Russia-America tension, a situation of Energy Crisis may arise in Europe. If the energy supply to Europe is stopped in Russia, then this situation can become even more serious. It is necessary that in order to deal with the situation of energy crisis, we have to pay attention to the solutions of Energy Crisis in time. Volcanoes and It's Types Solution of Energy Crisis For the solution of Energy Crisis, we should follow the steps taken by the government from time to time. At the same time, we should see whether we get any lesson from the energy crises that occurred in the past or not? At the time of the Second World War and the oil crisis of 1973 or in the subsequent years, many such steps were taken, which re...
