Which Best Explains How Greenhouse Gases Heat the Earth

This traps the energy which would otherwise go back into space and so has the effect of heating up the atmosphere. Which best explains how greenhouse gases heat the earth.

The greenhouse effect is the warming of Earth due to carbon dioxide and other gases in.

. When hearing the words greenhouse gas most people think immediately of carbon dioxide. They reflect the heat given off by geothermals. There are two main ways to stop the amount of greenhouse gases from increasing.

However too much greenhouse gas and Earth could be a fiery inferno like Venus average temperature 450C or 850F. The greenhouse gases in the. The sun shines through the Earths atmosphere and the earths surface warms up.

Carbon dioxide methane and water vapour are the most important greenhouse gases. If greenhouse gases are forcing Earth to absorb more energy than it emits why wouldnt global surface temperatures increase right away. During the day the Sun shines through the atmosphere.

Other factors have weaker effects. It sounds reasonable that if excess greenhouse gases in the atmosphere are causing Earth to absorb more energy than it reflects back into space that excess energy should heat up the atmosphere first. This means that water vapor is an important factor in models of the earths energy.

The greenhouse effect works much the same way on Earth. Earlier we noted that water vapor is the greenhouse gas that most affects the outgoing infrared radiation. Greenhouse gases are gaseslike carbon dioxide CO 2 methane and nitrous oxidethat keep the Earth warmer than it would be without them.

Industrial Waste and Landfills. Greenhouse gases GHGs trap the infrared radiation coming from the Sun and prevent it from escaping to outer space. Carbon dioxide top bar is the greatest factor.

This effect is caused by increased levels of carbon dioxide chlorofluorocarbons and other gases in the air many of them released by human activity. Human activities have led to increased concentrations of greenhouse gases that can remain in the atmosphere for decades centuries or longer so the corresponding warming effects will last. Greenhouse gas any gas that has the property of absorbing infrared radiation net heat energy emitted from Earths surface and reradiating it back to Earths surface thus contributing to the greenhouse effect.

The gases act like the glass walls of a greenhousethus the name greenhouse gas. Some of the Suns energy is reflected directly back to space the rest is absorbed by land ocean and the atmosphere. The greenhouse effect is the warming of climate that results when the atmosphere traps heat radiating from Earth toward space.

Greenhouse gases warm the planet. They trap the heat from the sun that is reflected by Earth. Without the gases that trap heat in Earths atmosphere Earth would be a frigid desert like Mars average temperature -55C or -67F.

When energy from the sun first reaches us it does so mainly as light. Nitrous oxide used in fertilizers is one of the contributors to the greenhouse effect in the atmosphere. Greenhouse gas molecules will absorb that light causing the bonds between atoms to vibrate says Jesse Kroll Professor of Civil and Environmental Engineering and Chemical Engineering at MIT.

The gases that contribute to the greenhouse effect. Earths surface warms up in the sunlight. They create heat from chemical reactions they cause in the atmosphere.

That sunlight creates warmth. Scientists know with virtual certainty that increasing greenhouse gas concentrations tend to warm the planet. In the mid-1800s physicist John Tyndall conducted experiments and found that some molecules present in the atmosphere such as carbon dioxide CO 2 actually trap heat from the sun and help keep the planet warm.

The reason they warm the Earth has to do with the way energy enters and leaves our atmosphere. These warmed gases radiate heat in all directions including back onto the earth heating the atmosphere. Greenhouse gases absorb energy that radiates upward from the Earths surface re-emitting heat to the lower atmosphere and warming the Earths surface.

Molecules that have the ability to trap heat in the. Greenhouse gases allow the suns light to shine onto Earths surface and then the gases such as ozone trap the heat that reflects back from the surface inside Earths atmosphere. With more greenhouse gases heat will stick around warming the planet.

Climate change is primarily caused by the accumulation of heat-trapping gases in the atmosphere. According to scientists the average temperature of Earth would drop from 14C 57F to as low as 18C.

The second bar includes methane CH4 nitrous oxide N2O and halocarbons such as chlorofluorocarbons CFCs. Greenhouse effect The warming of Earths atmosphere due to the buildup of heat-trapping gases such as carbon dioxide and methane. In computer-based models rising concentrations of greenhouse gases produce an increase in the average surface temperature of the earth over time.

They reradiate it back to Earths atmosphere. Scientists refer to these pollutants as greenhouse gases. Carbon dioxide CO 2 methane CH 4 nitrous oxide N 2 O Ozone O 3 and chlorofluorocarbons CFCs along with water vapour are.

Plants and trees take in carbon dioxide and release oxygen. Due to the cutting of trees there is a considerable increase in the greenhouse gases which increases the earths temperature. They then radiate this heat.

So the heat is not lost. Certain gases in the atmosphere resemble glass in a greenhouse allowing sunlight to pass into the greenhouse but blocking Earths heat from escaping into space. They capture the heat released by volcanoes on Earths surface.

The big trick of a greenhouse is that it doesnt let that warmth escape. At night Earths surface cools releasing. Greenhouse gases include carbon dioxide methane nitrous oxides and water vapor.

They are responsible for increasing the temperature of the atmosphere. Gases in the atmosphere such as carbon dioxide trap heat similar to the glass roof of a greenhouse. They get their name from greenhouses.

For the past 150 years burning fossil fuels and cutting down forests which naturally pull carbon dioxide out of the air has caused greenhouse gas levels to increase. The added greenhouse gases absorb the heat. Which Best Explains How Greenhouse Gases Heat the Earth Get link.

Greenhouse gases are gases that can trap heat. A greenhouse is full of windows that let in sunlight. The greenhouse effect is the way in which heat is trapped close to Earths 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.

To stop climate change we need to stop the amount of greenhouse gases like carbon dioxide from increasing. These heat-trapping gases are called greenhouse gases. Some of the heat will head away from the Earth some of it will be absorbed by another greenhouse gas molecule and some of it will wind up back at the planets surface again.

Greenhouse gases absorb heat rising from the surface of the earth.
