Our understanding of how atmospheric gases trap heat goes back almost 200 years to 1824 when Joseph Fourier described the greenhouse effect. This is known as their radiative effect, and it is the reason why the air we breathe is so different from that of our planet’s surface, which is covered in a layer of ice and snow.
In the early 20th century, however, scientists began to question the idea that greenhouse gases were the main cause of global warming. In the 1930s, for example, a group of German scientists, led by Otto Hahn, suggested that the increase in atmospheric CO2 was the result of a combination of natural and human-caused factors, including the burning of fossil fuels, deforestation and the use of fertilisers, pesticides and fertiliser-based fertilizers.

When did greenhouse effect discovered Mcq?
Fourier discovered the greenhouse effect in the 17th century. It is a phenomenon in which the amount of heat absorbed by an object is directly proportional to the square of the temperature difference between the object and the surrounding air. In other words, the greater the difference in temperature between you and your surroundings the more heat will be absorbed.
In the case of a greenhouse, this means that if you are standing in a room with a temperature of 100 degrees Fahrenheit, you will absorb 100 times as much heat from the air as you would if the room were at room temperature. If you were to stand in an air-conditioned room, on the other hand, your heat absorption would be reduced by a factor of 10,000.
The reason for this is that your body absorbs heat by convection, which is the process by which heat is transferred from one place to another by the movement of air and water vapor. However, when you stand on a hot surface, such as a sidewalk, or in front of an open window, it is possible for the heat to be transferred to your skin, causing you to sweat.
Who first used the term greenhouse effect?
In the early 20th century, scientists began to realize that the Earth’s climate was changing in ways that could not be explained by natural processes alone. In the 1930s, the U.S. National Academy of Sciences (NAS) convened a special committee to investigate the causes of global warming.
How did the greenhouse effect start?
In 1896, a swedish scientist named svante arrhenius claimed that fossil fuel burning may lead to global warming. (CDDR) is a relation between atmospheric carbon dioxide concentrations and the temperature of the Earth\’s surface. First of all, the rate of increase in atmospheric CO 2 is not constant. It varies with time and with the amount of energy used to produce the fuel.
For example, during the Little Ice Age, temperatures were much lower than they are today, but this did not mean that global temperatures had risen. In fact, they had actually fallen.
Why is it called greenhouse effect?
The greenhouse gas is called that because it gets absorbed by the Earth’s surface in the form of heat, which comes from the Sun in the form of heat. The greenhouse effect is the main reason why we are able to live on this planet, but it is not the only one. These gases are not harmful to humans or the environment.
However, they have a negative effect on the climate, because they trap heat and make it more difficult for plants and animals to grow. Climate change is caused by a combination of human activity and natural processes. Humans are responsible for about 80% of global warming. This is because of the burning of fossil fuels, deforestation and other human activities. Natural processes also play a role, for example the melting of polar ice caps and the increase in sea levels.
What is greenhouse effect in science?
The greenhouse effect is the way in which heat is trapped close to Earth’s surface by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet warmer than it would be without them.
What are greenhouse gases answer?
The so-called greenhouse effect is caused by them. Carbon dioxide, methane, and nitrous oxide can be found naturally in low concentrations. However, they can also be produced by human activities, such as the burning of fossil fuels. Carbon dioxide is the most important greenhouse gas.
It is produced naturally by plants and animals, and is released into the air when they photosynthesise. This process is known as photosynthesis. Carbon dioxide also contributes to the formation of clouds, which reflect sunlight back into space, reducing the amount of sunlight that reaches the Earth’s surface.
What is Kyoto Protocol Mcq?
The correct answer is that emissions of greenhouse gases are contained. It is an international agreement that aims to manage and reduce carbon dioxide emissions and greenhouse gases. Protocol was adopted in 1997 under the United Nations Framework Convention on Climate Change. It was designed to reduce greenhouse gas emissions from the use of fossil fuels, such as coal, oil, and natural gas. States is a signatory to the treaty.
It is not a treaty under U.S. law, but it does have the force of law. Act of 1970, it is illegal for any person to emit a pollutant into the air unless the person has a permit to do so. This is called a “polluter-pays” system. If a person does not pay for the pollution, he or she can be fined by the Environmental Protection Agency (EPA).
EPA has the power to impose fines of up to $25,000 per day for each day of noncompliance. In addition, the EPA can impose a penalty of $100 per ton of CO2 emitted, or $2,500 per million metric tons, whichever is greater.
