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 toastier than it would be without them. “Greenhouse gas concentrations are measured in parts per million (ppm), which is a measure of the total amount of greenhouse gases in the atmosphere.
For example, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and ozone (O3) are the three most common greenhouse gasses. Each of these gases has a different effect on the climate, depending on how much of them are present. CO2, for instance, traps heat at the surface, while methane traps it deep down.
Ozone is also a greenhouse gas, but it is not as effective at trapping heat as other gases, such as water vapour and water vapor, because it does not absorb as much energy from the Sun’s radiation. The three gases also vary in their ability to trap heat, with some gases being more effective than others at doing so.
This is because of how they interact with each other, as well as the fact that different gases absorb different amounts of energy.

What is the greenhouse effect?
The greenhouse effect is caused by some of the radiation from the Sun passing through the atmosphere but being absorbed and re-emitted in all directions by greenhouse gas Molecules and Clouds. The effect of this is to warm the Earth’s surface and the lower atmosphere by a small amount.
This warming effect is known as the “greenhouse effect” because it is caused by the absorption of infrared energy by gases in the upper atmosphere. For example, carbon dioxide (CO 2 ), methane (CH 4 ), nitrous oxide (N 2 O) and ozone (O 3 ) are all greenhouse gases.
Carbon dioxide and methane are the most important greenhouse gasses because they are responsible for about 80% of all global warming since the industrial revolution. Methane is the second-most important because of its role in warming the oceans. Nitrous oxides (NO x ) and chlorofluorocarbons (CFCs) are third and fourth on the list, respectively.
These gases are used in refrigerators, air conditioners, aerosols and aerosol sprays, as well as in industrial processes such as power plants and factories.
Why is it called greenhouse effect?
The natural process that warms the Earth’s surface is what it is. The greenhouse effect is caused by the exchange of incoming and outgoing radiation that warms the planet in a similar way to a greenhouse. When the sun is at its highest point in the sky, it radiates more energy than it receives back from the atmosphere. As a result, the surface of the earth is warmer than at any other time in its history.
This is known as the “greenhouse effect” and it has been a major contributor to global warming since the mid-20th century, when it was first observed. Since then, scientists have been trying to figure out how much of this warming is due to human activity. In recent years, they have come up with a range of estimates, ranging from a low of about 1.5 degrees Celsius to as high as 3.6 degrees C (5.4 degrees F).
The most recent estimate, published in 2013 by the Intergovernmental Panel on Climate Change (IPCC), is that human activities have increased the average global surface temperature by about 0.8 degree Celsius (1.1 degrees Fahrenheit) over the past 100 years.
What is greenhouse effect and its causes?
Greenhouse effect, a warming of Earth’s surface and troposphere caused by the presence of water, carbon dioxide, methane, and certain other gases in the air. The greenhouse effect is a natural phenomenon that occurs when the concentration of a particular gas, such as CO2, increases.
This increases the amount of sunlight that reaches the Earth, which in turn causes the planet to warm up. As a result of this warming, the surface temperature on Earth increases, causing more clouds to form and more heat to be absorbed by them. These clouds then reflect more sunlight back into space, increasing the temperature further.
In turn, this increase in temperature causes more water vapor to condense into ice crystals, forming clouds. When the clouds are large enough, they can block out the sun’s rays and cause a cooling effect. The result is that the world is warmer than it would otherwise be.
What are greenhouse gases for kids?
The gases in the atmosphere trap heat. They prevent the heat that the sunlight brings to the surface from escaping into space by allowing sunlight to pass through the atmosphere. The amount of carbon dioxide in the air today is about 400 parts per million (ppm). That’s about the same as it was at the beginning of the Industrial Revolution in 1750, when the first coal-fired power plants were built.
Today, the concentration of CO2 is higher than at any time in at least the last 800,000 years, according to NASA’s Goddard Institute for Space Studies (GISS) in New York City. The last time the level was this high was during the Permian-Triassic Extinction 252 million years ago, which wiped out 90 percent of all marine life on Earth, including the dinosaurs.
Is greenhouse effect good or bad?
It’s a good thing that the greenhouse effect is a good thing. The average temperature of the planet is 59 degrees Fahrenheit (15 degrees Celsius) and it keeps life interesting. If it weren’t for it, the world would be more like Mars than Earth. But there’s a downside to greenhouse gases, too. They trap heat in the atmosphere, making it warmer than it would otherwise be.
That’s bad news for plants and animals that depend on them for food, shelter, and protection from the elements. In fact, it’s one of the main reasons why climate change is such a big deal. If we don’t do something about it, we’re going to have to deal with the consequences for a long time to come.
How greenhouse effect causes global warming?
The greenhouse effect is the main driver of climate change. Some gases in the Earth’s atmosphere act a bit like the glass in a greenhouse, trapping the sun’s heat and stopping it from leaking out into space. These gases include carbon dioxide (CO 2 ), methane (CH 4 ), nitrous oxide (N 2 O) and ozone (O 3 ).
The amount of each of these gases varies depending on the time of year, the location of the planet, and the type of plant or animal that lives there. For example, CO 2 levels are highest during the summer months, when plants and animals are most active. In addition to trapping heat, greenhouse gases also contribute to global warming, which is caused by the buildup of heat-trapping gases, such as water vapor and methane.
Carbon dioxide Carbon dioxide, also known as carbon monoxide, is a gas that comes from the burning of fossil fuels. It is produced by plants, animals and humans as a byproduct of photosynthesis. When plants photosynthesize, they take in sunlight and convert it into chemical energy that they use to grow and reproduce. This process is called “photosynthesis,” and it is responsible for the production of all the oxygen we breathe, as well as the carbon in our bodies.
