Top 12 main causes of global warming list – listovative grade 6 science electricity multiple choice test


Global warming, can be defined as an increase in the earth’s atmospheric, oceanic temperatures and an overall change in earth’s atmosphere including a rise in sea levels and variability of snow falls. electricity generation in india Climate change and associated impacts vary from region to region around the globe. Due to increase in the greenhouse effect resulting especially from pollution and other activities such as, greenhouse gas emissions produced by human activities mainly industrial processes and transportation.

According to, IPCC(Intergovernmental Panel on Climate change) “Greenhouse gases effectively absorb thermal infra-red radiation, emitted by the Earth’s surface, by the atmosphere itself due to the same gases, and by clouds. Atmospheric radiation is emitted to all sides. Thus, greenhouse gases trap heat within the surface-troposphere system. This is called the Greenhouse effect”

The CO2 concentration in the atmosphere by about thirty percent, due to Human beings have increased, the increase is proportional to increases in fossil fuel combustion ,for electricity generation, transportation, and heating, and also the manufacture of cement , (human caused) emissions. It is predicted that we’ll soon reach carbon dioxide concentrations that haven’t been seen on Earth in the last 50 million years, which is eventually leading to changes in the Earth’s average surface temperature, which is really proving fatal to human lives. 11. Ozone Depletion

Increase in ozone levels in the stratosphere over Antarctica, are the result of complex chemical processes. The return of the Sun at the end of winter triggers photochemical reactions that lead to the destruction of ozone in the stratosphere. As reported Over the Arctic the gradual development of an annual decline during the 1990s, has been observed. The Protection of the Ozone Layer amendments has been issued to eliminate certain CFCs from industrial production, the substantial destruction of ozone in the stratosphere over Antarctica, has not seen any improvement till date. 10. electricity questions for class 10 Deforestation

The use of forests for fuel (both wood, for charcoal and other necessary lifestyle products) is one cause of deforestation. In order satiate ourselves, for wood and other products, mainly habitat and to build farms we are chopping forests which is not a good sign and has also leads to decrease in rainfalls. Forests are very human friendly, they clean the air as they act as natural filters remove and store carbon dioxide from the atmosphere, and this deforestation releases large amounts of carbon, as well as reducing the amount of carbon gas capture on the earth. 9. Methane and Nitrous oxide emissions from agriculture, Arctic sea beds and factories

Methane is one of the greenhouse gases, which causes global warming. When organic matter is broken down by bacteria under oxygen-starved conditions as in agricultural fields, methane is produced. arkansas gas and oil commission The process also takes place in the intestines of herbivorous animals, and with the increase in the amount of concentrated livestock production, the levels of methane released into the atmosphere is increasing. Another source of methane is methane clathrate, a compound in large amounts of methane trapped in the crystal structure of ice. gas 87 89 91 As methane escapes from the Arctic seabed, the rate of global warming increases, accordingly. 8. Aerosols present in the Atmosphere

Increase in sea levels is the result of melting of two massive ice sheets in Antarctica and Greenland as researched by scientists. However, many nations around the world will experience the effects of rising sea levels, which could displace millions of people. The Maldives a country is already looking for a new home due to rising sea levels. Majority of Americans living in coastal states, are facing large impacts due to global warming. electricity outage chicago Seawater expands, takes more space in the ocean and causes a surplus rise in water level and also the melting of ice over land, which then adds water to the ocean. 6. Plankton boom due to warming seas

Water vapour is increasing in the atmosphere due to carbon dioxide-induced warming. Two-thirds of the heat trapped by greenhouse gases is contained in water vapor, and as the average temperature on the planet to raises, the amount of water vapour rises in turn, leading to untimely rainfall which may further cause other natural calamities such as floods. 4. Sunspots

Sunspots are dark patches on the sun’s surface that block hot solar plasma. Increase in solar activities changes the Earth’s solar radiation levels, thereby causing short-term warming cycles. Surrounding sunspots are bright patches known as faculae. These patches give off greater than normal radiation, and they are more powerful than the darker, cooler patches. This means that the total average energy over a 30-day solar rotation increases, which gives way to many other after effects 3. gas dryer vs electric dryer operating cost Burning of Fossil Fuels

Each time a fossil fuel burn, carbon dioxide levels in the atmosphere increase. As we know carbon dioxide absorbs infra-red energy emitted from the earth’s surface, preventing it from returning to space. Auto mobiles, Carbon emissions from the burning of gasoline to power cars, trucks, and other methods of transportation. Electricity generation requires, coal is the largest producer of carbon dioxide emissions, Therefore countries across the world want to switch to nuclear power plants. 2. Mining activities
