Which Two Gases Are Primarily Responsible For The Greenhouse Effect?

Water vapor and carbon dioxide were good absorbers. Water vapor, for example, absorbs infrared light at wavelengths between 400 and 700 nanometers. Carbon dioxide, on the other hand, has a much wider range of absorption and emission wavelengths, ranging from 400 to 700 micrometers. In other words, the greenhouse effect is much stronger for water vapour than it is for CO 2.

This means that the amount of greenhouse gases that can be emitted from the Earth is directly proportional to the size of the water molecule that is being absorbed or emitted. This is because water molecules are much smaller than carbon molecules, so the absorption or emission of one molecule of water is more important than that of another.

What are the two major greenhouse gases?

Carbon dioxide, methane, nitrous oxide, and various synthetic chemicals are greenhouse gasses. Carbon dioxide is the most important greenhouse gas because it accounts for the greatest portion of the warming since the mid-20th century. Methane is the second-most important, accounting for about one-third of global warming. Nitrous oxides are the third-largest contributor to warming, followed by carbon monoxide and sulfur dioxide.

Synthetic chemicals, such as hydrofluorocarbons (HFCs) and perfluorooctanoic acid (PFOA), account for less than 1 percent of total greenhouse-gas emissions, according to the Intergovernmental Panel on Climate Change (IPCC). States, emissions from the transportation sector are responsible for more than half of U.S. GHG emissions.

The largest single source of these emissions is passenger vehicles, which accounted for nearly half (47 percent) of all passenger-vehicle emissions in 2012. In addition to passenger cars and light trucks, the largest sources of passenger vehicle emissions are buses, light-duty trucks and vans, vans and sport utility vehicles (SUVs), and motorcycles.

Which two gases are primarily responsible for the greenhouse effect quizlet?

Water, carbon dioxide, and methane. It absorbs infrared radiation from the sun and radiates it back to space. Carbon dioxide is a gas that is produced by the burning of fossil fuels.

Methane, on the other hand, is an organic compound that occurs naturally in soil and is released into the air as a byproduct of the decomposition of organic matter. Both gases absorb and emit radiation, but the amount of radiation absorbed by water is much greater than that emitted by CO2.

This is because water absorbs more energy from infrared light than does any other gas, so it is able to radiate more of that light back into space than it absorbs. This means that water has a much larger effect on global warming than either of these gases.

Which gases are considered greenhouse gases?

Water vapor, carbon dioxide, methane, nitrous oxide, and hydrofluorocarbons are greenhouse gases that occur naturally and from human activities. (EIA) estimates that the total amount of greenhouse gases emitted in the United States in 2012 was about 1.1 billion metric tons, or about 0.9 percent of the nation’s total energy consumption. EIA also estimated that in 2013, the amount emitted would be about 2.2 billion tons.

These estimates are based on data from the Environmental Protection Agency (EPA), the Department of Energy (DOE), and the Bureau of Land Management (BLM). DOE are responsible for regulating greenhouse gas emissions from power plants, which are the largest source of these emissions. In 2012, power plant emissions accounted for more than one-third of all greenhouse-gas emissions, according to the EPA’s National Inventory of Greenhouse Gas Emissions and Sinks (NIHGES), which is the most recent data available for the year.

Is no2 a greenhouse gas?

Nitrogen dioxide and nitric oxide are not greenhouse gases and should not be confused with n2o gas. Nitrogen dioxide is a gas that is produced by the burning of fossil fuels, such as coal, oil, and natural gas. It is the main component of smog.

Nitrogen oxides are also produced from the combustion of wood and other biomass, as well as from other sources, including agricultural fertilizers, livestock manure, sewage sludge, industrial effluents, municipal solid waste, agricultural pesticides, herbicides, insecticides and fungicides. These sources of nitrogen oxide also contribute to the formation of ozone, a pollutant that can be harmful to human health and the environment.

What two gases make up 99% of Earth’s atmosphere?

Nitrogen and oxygen make up 99 percent of the gases in dry air, with other trace gases making up 1 percent. The researchers found that the amount of nitrogen in the air is directly related to the number of people living in a given area. For example, a city with 1,000 people per square kilometer would have more than twice as much nitrogen as one with only 100 people.

Why is CO2 the main greenhouse gas?

The heat is trapped around the Earth. The amount of heat absorbed by a molecule of carbon dioxide depends on the temperature of the air it is in, and how long it has been at that temperature. The longer the molecule is at a given temperature, the more heat it absorbs. At the same time, it also takes more energy to absorb heat than it does to emit it.

Thus, a longer-lived molecule has a higher energy-absorption rate than one that is shorter lived. As a result, at higher temperatures, longer molecules have a greater heat-trapping capacity than shorter molecules. , which is a measure of how much heat is trapped in a particular molecule, is the ratio of its temperature to its molecular weight.
