What are the 5 major greenhouse gases?
The main gases responsible for the greenhouse effect include
carbon dioxide, methane, nitrous oxide, and water vapor
(which all occur naturally), and fluorinated gases (which are synthetic).

What are 4 naturally occurring greenhouse gases?
Many greenhouse gases occur naturally in the atmosphere, such as
carbon dioxide, methane, water vapor, and nitrous oxide
, while others are synthetic. Those that are man-made include the chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs) and Perfluorocarbons (PFCs), as well as sulfur hexafluoride (SF

Is NOx a greenhouse gas?
Nitrogen oxides (NOx) act
as indirect greenhouse gases
by producing the tropospheric greenhouse gas ‘ozone’ via photochemical reactions in the atmosphere. … Sources of NOx include fossil fuel burning, biomass burning and emission from soils.
What are the top 3 sources of greenhouse gases?
Global Manmade Greenhouse Gas Emissions by Sector, 2013
Globally, the primary sources of greenhouse gas emissions are
electricity and heat
(31%), agriculture (11%), transportation (15%), forestry (6%) and manufacturing (12%). Energy production of all types accounts for 72 percent of all emissions.
What are the most potent greenhouse gases?
Water vapor
is the most potent of the greenhouse gases in Earth’s atmosphere, and it’s sort of a unique player among the greenhouse gases.
What is the main source of greenhouse gases?
The largest source of greenhouse gas emissions from human activities in the United States is from
burning fossil fuels for electricity, heat, and transportation
.
What are greenhouse gases quizlet?
Any gases compound in the atmosphere that is capable of absorbing infrared radiation thereby trapping and holding heat in the atmosphere. … Examples of these gases are :
water vapor, carbon dioxide, methane, nitrous oxide and ozone
.
How many greenhouse gases are there?

What are synthetic greenhouse gases?
Synthetic greenhouse gases are
artificial chemicals commonly used in refrigeration and air conditioning, fire extinguishing, foam production and in medical aerosols
. … However, synthetic greenhouse gases generally have high global warming potential; when they are released, they trap heat in the atmosphere.
Which gas is not a major greenhouse gas?
The various greenhouse gases are carbon dioxide, methane, chlorofluorocarbon, ozone, nitrous oxide, and water vapor. Hence the gas which is not a greenhouse gas is
nitrogen
and the correct answer for the given question is option d).
What are greenhouse gases for kids?
Gases in the atmosphere, such as
carbon dioxide
, trap heat similar to the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases. During the day, the Sun shines through the atmosphere. Earth’s surface warms up in the sunlight.
