How is the greenhouse effect caused on a molecular level?
The greenhouse effect occurs when certain gases in Earth's atmosphere, such as carbon dioxide and methane, trap heat from the sun. These gases absorb infrared radiation emitted by Earth's surface, preventing some of the heat from escaping into space. This results in a warming effect on the planet.
Identify one important effect of the rise in the level of greenhouse gases?
One important effect of the rise in the level of greenhouse gases is global warming. Greenhouse gases trap heat in the Earth's atmosphere, causing the planet's average temperature to increase. This can lead to various consequences such as rising sea levels, more frequent and severe weather events, and disruptions to ecosystems.
Do greenhouse gases increase global temperature?
Yes. In the absence of greenhouse gases, the world would be some 30 degrees celsius colder. At the other extreme, greenhouse gases contribute to the extreme heat on the planet Venus. So, a normal level of greenhouse gases, including carbon dioxide, is very desirable. The present increase in the level of atmospheric carbon dioxide is considered to be the main cause of increasing average global temperatures.
How can you reduce the level of greenhouse gases in the atmosphere?
Afforestation. The only way is to plant more trees.
Why the level of greenhouse gases in the atmosphere is rising?
The level of greenhouse gases in the atmosphere is rising as the gases responsible are produced without any attempt to reduce the levels. The gases such as Methane, water vapors, Carbon dioxide ( CO2 ), Nitrous Oxide and especially chloroflurocarbons ( CFCs ) are increasing day by day as it is used in manufacturing many products. If such trend continues it may result in the huge climatic changes which may result in mass deaths due to extreme weather conditions and diseases caused by such gases
What is another name for enhanced greenhouse effect?
The greenhouse effect is the natural process by which greenhouse gases keep the earth's temperature at a comfortable level suitable for human existence. The enhanced greenhouse effect is the increase in greenhouse gases that is leading to global warming. The term "enhanced greenhouse effect" is also referred to as the "anthropogenic greenhouse effect" and is the idea that humans may have an effect on global climate. It is also referred to as the "runaway greenhouse effect".
What is ozone trapped in the troposphere that is formed by human activities?
The ozone at ground level is a pollutant. It is trapped by other greenhouse gases.
How are excess greenhouse gases affecting the temperature of earth's atmosphere?
Greenhouse gases help keep the earth's temperature at a comfortable level suitable for human existence. When we increase the atmospheric concentration of greenhouse gases above their natural level, this leads to global warming, in other words higher average temperatures across the globe.
How does seawater greenhouse affect land?
Green house gases course for global warming. Global warming causes increasing of sea level.
How does heat affect the Earth's surface?
Infrared heat rises from the surface of the earth into the troposphere (the lowest level of the atmosphere). It is captured there by greenhouse gases, so the troposphere warms. This is called the greenhouse effect, and too much greenhouse gas means global warming.
Is O2 a greenhouse gas?
No, it isn't. Water vapour, though, is a greenhouse gas. To be greenhouse gas the molecule must have a strong absorbence in the IR frequencies of light. Neither oxygen nor nitrogen (the major gases in the atmosphere) have this characteristic. To be a greenhouse gas the molecule must have at least three atoms. Water vapor is the most prevalent greenhouse gas in every measurable way. Carbon dioxide comes in a distant second with 0.04% of the atmosphere and about 5% of all warming. The rest of the gases that are involved are even more removed from the major gases in terms of warming and concentrations.
Is ozone a greenhouse gas?
Yes, ozone is considered a greenhouse gas. While ozone in the stratosphere protects us from the sun's harmful ultraviolet radiation, at ground level it can contribute to warming the Earth's surface as a greenhouse gas.
