Depletion of ozone layer - class-X

The various greenhouse gases are $ { CO } _{ 2 }, { CH } _{ 4 }, { CFC } _{ s } $ and $ { N } _{ 2 }{ O } $. Excessive use of fossil fuel is adding more $ { CO } _{ 2 } $ to atmosphere. This increase in concentration of greenhouse gases has led to considerable heating of earth leading to global warming. During the pas century, the temperature of earth has increased by $ 0.6 $.

Ozone doesn't absorb infrared radiation , it absorbs ultraviolet radiations .

Oxygen is not greenhouse gas, because they are transparent to infrared light.

Because Green House Gases are responsible to trap heat in earth surface. If green house gases are absent, the temperature of Earth shall fall down to -18 degree Celcius

Greenhouse gases are the gases that contribute to the greenhouse effect by absorbing the earth's heat and re-radiating it towards the earth. Carbon dioxide is the highest (among gases) contributor towards greenhouse effect and contributes about 9-26%, followed by methane (contributes 4-9%), and ozone (3-7%). Over the past few years, carbon dioxide has caused most of the global warming as it is present in abundance in the atmosphere and its amount is increasing over the years. So, even though other gases have a more contributing effect per molecule, the amount of carbon dioxide is so high that it contributes more than the other gases. Due to this carbon dioxide is considered the main greenhouse gas. 

• Carbon dioxide (CO₂)- 60%
• Methane (CH₄)- 20%
• Chlorofluorocarbons (CFC)- 14%
• Nitrous oxide (N₂O)- 6%

Avails cannot try photo photo there are number of various reasons why they are unable to live on land first of all their bodies are not designed to hold the weight on the land which is unknown by and environment secondly they have a thick layer of blubber which is fatty tissue and lack of water well quickly overheat get dehydrated and try out the temperature of the water is essential for the survival correct option is increasing body temperature

Hydrofluorocarbons (HFCs) are synthetic, man-made compounds used in refrigeration and air conditioning, known for their high global warming potential.

Water vapor is the most abundant greenhouse gas in the atmosphere, though its concentration is highly variable and it is not typically considered a direct driver of anthropogenic climate change.

Carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) are all greenhouse gases that trap heat in the atmosphere. They are called 'radiatively active' gases because they absorb and emit infrared radiation, though the question incorrectly states 'radioactively.' Each of these gases contributes to the natural greenhouse effect to varying degrees.

The greenhouse effect is the process by which greenhouse gases in the atmosphere trap heat from the sun, preventing it from escaping back into space and thereby warming the Earth.

Both water vapor and carbon dioxide are major contributors to the natural greenhouse effect, which maintains the Earth's temperature.

Greenhouse gases are chemical substances that absorb infrared radiation and increase the Earth's surface temperature by trapping heat.

The warming up of the atmosphere due to trapped radiation is called green house effect. Green house gases like carbon dioxide, methane, nitrous oxide etc; increase in green house gases leads to global  warming.

When solar radiation enters the atmosphere, it is absorbed by the clouds and gases and heats the earth's surface. The earth, in return, reflects some of this heat into the atmosphere as infrared radiation. Most of this infrared radiation gets absorbed by atmospheric gases such as carbon dioxide, methane, nitrous oxide, and ozone, commonly known as greenhouse gases. These gases send the infrared radiation back to the earth's surface, thereby heating the surface again. This cycle repeats several times, thereby resulting in the greenhouse effect.

(The greenhouse effect is the natural process by which the atmosphere traps some of the Sun's energy,  warming the Earth enough to support life.  Most mainstream scientists believe a human-driven increase in "greenhouse gases" is increasing the effect artificially.
These gases include carbon dioxide, methane, nitrous oxide, water vapour, CFCs, ozone etc. Ozone in the stratosphere acts as a protective layer, but harmful if it is present in the troposphere).

A national CDM (clean development mechanism) authority has set up in December 2003 to formulate projects for reducing emission of CO$ _2$ and other green house gases. 

Solar radiation is absorbed in the Earth's surface and emitted as thermal energy that can be re-absorbed by greenhouse gases. Greenhouse gases include water vapor, carbon dioxide, ozone, and methane; the major components of atmospheric gas nitrogen, oxygen, and argon are transparent to infrared radiation. The greenhouse effect insulates the earth's surface, making it hospitable to life; however, human activities have increased the concentration of these gases, causing global warming.

The assertion that the greenhouse effect is due to a thick layer of CO2 is an oversimplification, as it involves multiple gases and processes. The reason correctly describes how a greenhouse works, but it does not explain why the greenhouse effect on Earth is specifically attributed to a 'thick layer of CO2'.

Greenhouse gases are called so because they are capable of absorbing the insolation from the sun and keeping it within the troposphere, thereby increasing the overall temperature of the earth, called global warming. Carbon dioxide, methane, nitrous oxide, ozone, Chlorofluorocarbons and sulphur hexafluoride are considered to be the potent greenhouse gases. Oxygen is not a greenhouse gas.

The gases in the troposphere of the atmosphere absorb the sun radiations and trap them so that they do not reflect back. This process allows the heat to remain trapped with in the atmosphere and the earth surface remains warm. This process is called greenhouse effect and the absorbed radiations striking the earth's surface are called green house flux. Carbon dioxide, water vapour, oxides of nitrogen are useful for this purpose. 

A greenhouse gas absorb radiation and emit heat energy maintaining the Earth's temperature. However, when released in excess amounts, they cause global warming. Sources are volcanic eruptions, burning of fossil fuels, deforestation, vehicular exhausts, industrial emissions etc. contribute to the greenhouse gases. Carbon dioxide, Chlorinated hydrocarbon (CHC), Methane and oxides of nitrogen are considered to be the major greenhouse gases.

Paddy or the rice fields are water-logged to allow the growth of the rice crops. Due to the respiration, the carbon dioxide is released in heavy amounts by the bacteria present in the water-logged soil. However, as the season progresses, the methane-releasing bacteria are seen to occupy the paddy field. Together with the carbon dioxide, the methane becomes a greenhouse gas resulting in global warming

A greenhouse gas absorb radiation and emit heat energy maintaining the Earth's temperature. Sources are volcanic eruptions, burning of fossil fuels, deforestation, vehicular emission, industrial exhausts etc. which have increased the concentration of carbon dioxide in the atmosphere. The oxygen and hydrogen are transparent gases having symmetrical molecules of identical atoms, unable to rotate and vibrate.

Ozone is a significant gas in the stratosphere because it absorbs the UV rays and do not allow them to reach the earth's surface. There it is formed by the reaction of oxygen with UV rays. However, tropospheric or ground-level ozone is formed as a secondary pollutant and is harmful. It acts as a major constituent of the photochemical smog. It also traps and reflect back the infra-red rays coming from the earth's surface. Here, it is formed when the primary pollutants react with the oxygen in the presence of sunlight. So, it acts as a greenhouse gas.

Certain gases such as methane, carbon dioxide, chlorofluorocarbons are called greenhouse gases because they absorb and thus trap some of the radiation. The nitrogen is the second most abundant act found in the atmosphere after oxygen. These gases do not have the ability to intercept infrared radiation and hence they do not contribute to causing of the greenhouse effect. Methane, carbon dioxide and chlorofluorocarbons are potent greenhouse gases.

A greenhouse gas is a gas in an atmosphere that absorbs and emits radiant energy within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapour, carbon dioxide, methane, CFC's, nitrous oxide, and ozone.

Carbon dioxide and methane are naturally occurring gases. Nitrous oxides are formed due to denitrification and combustion of the fossil fuels. CFCs are used as refrigerants and propellants. Ozone is formed as a secondary pollutant. All these are greenhouse gases because they show greenhouse effect by absorbing the the long-wavelength infra-red radiations coming from the earth's surface and preventing from leaving the atmosphere. This effect is responsible for maintaining the ambient temperature on the earth. Their  amounts have increased over the past years and this has adversely affected the global temperature by raiding it. This is called global warming and is responsible for climate change. 

Natural gas actually supplies roughly 24 percent of global energy needs, making the statement that it supplies five percent incorrect. The other statements regarding greenhouse gases, CFC potency, and atmospheric lifetimes are factual.

Greenhouse gases are named for their ability to mimic the effect of a greenhouse, where glass allows sunlight in but traps the heat reradiated from the surface.

China is currently the world's largest emitter of greenhouse gases, and historically, it has been the second-largest emitter after the USA for many years.

The burning of fossil fuels such as gasoline, coal, oil, natural gas in combustion reactions results in the production of carbon dioxide. There are cyclic variations of Carbon dioxide concentration in the atmosphere due to this reason. 

greenhouse gases are those gases which absorb the heat or thermal infrared radiations of the sun and is responsible for an increase in the temperature of the earth's surface .there are several greenhouse gases that are produced either naturally or is being emitted in the atmosphere by a man-made source. The most abundant or major greenhouse gas is Carbon Dioxide.

Carbon dioxide is one of the most abundant and major greenhouse gas which entraps the heat and causes the rise in temperature of the earth surface hence is greatly responsible for global warming also.

Relative concentration of various greenhouse gases in the atmosphere is as: CO$ _2$ (60%), CH$ _4$ (20%), CFCs (14%) and N$ _2$O (6%).

Oxygen is released in the atmosphere through the process of photosynthesis. Carbon dioxide is released by different human activities like the burning of fossil fuels,  deforestation, burning of petrol etc.

The Kyoto Protocol was an international treaty that extended the 1992 United Nations Framework Convention on Climate Change, committing state parties to reduce greenhouse gas emissions based on the scientific consensus that global warming is occurring.

Water vapor and carbon dioxide are the most significant contributors to the greenhouse effect in the Earth's atmosphere, with water vapor being the most abundant and CO2 being the most significant anthropogenic contributor.

Venus has a thick atmosphere composed primarily of carbon dioxide, which creates an extreme greenhouse effect, resulting in surface temperatures hot enough to melt lead.

Methane (CH4) is a very potent greenhouse gas, with a global warming potential significantly higher than that of carbon dioxide over a 100-year period.

The greenhouse effect is primarily driven by the accumulation of greenhouse gases in the atmosphere, which trap heat. Carbon dioxide (CO2) is the most significant anthropogenic greenhouse gas contributing to this effect.

Trifluoromethyl sulfur pentafluoride (SF5CF3) is an extremely potent greenhouse gas with a global warming potential thousands of times higher than carbon dioxide. While CO2 is the most abundant, this specific compound is significantly more effective at trapping heat per molecule.

Without the natural greenhouse effect, Earth's average surface temperature would be approximately -18 degrees Celsius. The current average temperature is about 15 degrees Celsius due to the natural greenhouse effect.

Greenhouse gases regulate the Earth's temperature by absorbing and re-emitting infrared radiation. Changing their concentration directly alters the energy balance of the planet.

The Kyoto Protocol originally recognized six categories of greenhouse gases: carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride.

Ibuki, also known as GOSAT (Greenhouse Gases Observing Satellite), was launched by Japan in 2009 as the world's first satellite dedicated to monitoring greenhouse gases.

A carbon footprint is defined as the total amount of greenhouse gases, including carbon dioxide and methane, generated by our actions or by a specific product.

As noted previously, the GOSAT satellite launched by Japan in 2009 is named Ibuki.

In India, paddy or rice cultivation is done across the different regions and in different seasons. The availability of the monsoon and irrigation facility further promote the paddy cultivation. The paddy cultivation occurs in water logged condition and favours the release of methane after the bacteria has respired aerobically. So, the methane release in the country is largely due to the rice fields. Sugarcane plantations, wheat fields and fruit orchard do not need water-logged condition.

The microbes in the paddy field respire and release the carbon dioxide. The increase in carbon dioxide increases the nearby temperature. This further results in the release of methane. Methane, in combination with carbon dioxide becomes a potent greenhouse gas. They trap the sun radiations, preventing them from reflecting back and falling on the earth's surface. This results in raising the overall global temperature. 

Nitrous oxide is a powerful greenhouse gas produced by soil cultivation practices, especially the use of commercial organic fertilizers (including manure), biomass burning etc, This is done by a process of nitrification which converts the nitrogen in fertilizer to the production of nitrous oxide. The excessive use of the fertilizers thereby results in an increase in the nitrous oxide production.

The greenhouse gases are called so because they absorb the long wave infra-red radiations reflected from the earth's surface and trap them such that they do not get reflected back to space. This trapping of the long wave infra-red radiations causes an increase in the temperature of the atmosphere, called global warming. CO$ _{2}$, CH$ _{4}$, N$ _{2}$O, CFCs are the gases that are capable of showing greenhouse effect. These have increased in the concentration over the years due to the anthropogenic activities.

Global warming potential (GWP) is a measure of how much heat a greenhouse gas traps in the atmosphere up to a specific time horizon, relative to carbon dioxide. It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide and is expressed as a factor of carbon dioxide an index of global warming potential for methane, carbon monoxide, nitrous oxide and CFCs relative to that of carbon dioxide. The major contribution is from CO$ _2$ (60%),CH$ _4$ (20%), CFC and N$ _2$O attributes to 14% and 6% respectively.
