Earth is a comfortable place for humans to live because of the greenhouse effect. In the past, greenhouse gases like carbon dioxide and methane were thought to be the main cause of global warming. However, recent research has shown that these gases play a much smaller role in warming the planet than previously thought.

How does greenhouse gas heat the Earth?
This increases the planet’s average temperature and causes more water to evaporate out of the air and into the oceans. The oceans absorb a lot of heat from the sun, too, but they don’t absorb as much heat as the land. That’s because the ocean absorbs more heat than it emits, so it doesn’t warm up as fast as land does.
The result is that the world’s oceans are warming much more slowly than land is. In fact, the average global temperature has risen by about 0.8 degrees Fahrenheit (0.4 degrees Celsius) since the late 19th century, according to the National Oceanic and Atmospheric Administration (NOAA).
Which best describes greenhouse gas?
Greenhouse gas, any gas that has the property of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the greenhouse effect. (CO 2 ) is the main greenhouse gas. It is produced by the burning of fossil fuels, such as coal, oil, natural gas and nuclear power.
CO 2 is also emitted by plants and animals, as well as by human activities, including deforestation and land-use change. Since then, it has increased by about 1.5 ppm per year, which is about the same rate as the increase in global average temperature (about 0.8°C per decade).
The rate of increase has slowed in recent years, however, due to a combination of natural and human-caused climate change, but it is still increasing at a rapid rate.
What is greenhouse effect short answer?
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 do greenhouse gases do?
Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth’s outgoing energy, thus contributing to global warming. The increase in greenhouse gas emissions is due to the burning of fossil fuels and deforestation, the researchers said.
What is an example of greenhouse effect?
The warming of a car’s interior when the vehicle is left out in the sun is one example of the greenhouse effect that most of us experience. This is due to the fact that the air inside the car gets warmer as it warms up. The same is true for your home.
As the temperature inside rises, so does the amount of heat that can be absorbed by the walls and ceiling. The hotter the room, the more heat it can absorb, and the warmer it gets. If you have a large living space, you can expect to see a significant increase in your heating costs as a result of this effect.
Which of the following is responsible for greenhouse effect?
Carbon dioxide and methane make up the majority of greenhouse gases. The study, published in Nature Geoscience, found that the amount of carbon dioxide released by the burning of coal, oil and gas in China has increased by more than 50 per cent over the past 30 years, while the emissions of methane have risen by almost 40 times over that period.
Why does the greenhouse effect occur?
In the case of coal, the gases are methane and nitrous oxide. Methane is a potent greenhouse gas, and it is produced by the burning of natural gas. Nitrous oxides are produced when coal is burned to produce electricity.
When these gases enter the air, they absorb some of the sunlight that would otherwise be reflected back into space. As a result, more sunlight is absorbed, increasing the amount of heat that is trapped. This heat is then released as heat waves, droughts, floods and other extreme weather events.
Which one of the following statements is true with regard to a greenhouse?
This is a very important point, because it means that greenhouse gases are not the only cause of global warming. It is also possible that other factors, such as changes in solar activity, volcanic eruptions, etc., also play a role in warming the planet. However, it is very unlikely that any one of these factors is responsible for all the warming that has taken place over the past century.
