A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown These structures range in size from small sheds to industrialsized buildings A miniature greenhouse is known as a cold frame The greenhouse effect, in turn, is one of the leading causes of global warming The most significant greenhouse gases, according to the Environmental Protection Agency (EPA), are water vapor (H2O The natural greenhouse effect The natural greenhouse effect is a phenomenon caused by gases naturally present in the atmosphere that affect the behaviour of the heat energy radiated by the sun In simple terms, sunlight (shortwave radiation) passes through the atmosphere, and is absorbed by Earth's surface

What is the definition of a greenhouse gas
What is the definition of a greenhouse gas-Word forms (plural) greenhouse gases noun ( Extractive engineering General) A greenhouse gas is a gas that contributes to the greenhouse effect by absorbing infrared radiation in the atmosphere Carbon dioxide is considered to be a greenhouse gas because it traps heat radiated into the atmosphere Carbon dioxide is widely considered to beAn atmospheric heating phenomenon, caused by shortwave solar radiation being readily transmitted inward through the earth's atmosphere but longerwavelength heat radiation less readily transmitted outward, owing to its absorption by atmospheric carbon dioxide, water vapor, methane, and other gases;

Greenhouse gas meaning 1 a gas that causes the greenhouse effect, especially carbon dioxide 2 a gas that causes the Learn moreGreenhouse gases are gases in Earth's atmosphere that trap heat They let sunlight pass through the atmosphere, but they prevent the heat that the sunlight brings from leaving the atmosphere The main greenhouse gases areAs a greenhouse gas, the higher concentration of water vapor is then able to absorb more thermal infrared energy radiated from the Earth, thus further warming the atmosphere The warmer atmosphere can then hold more water vapor and so on and so on This is referred to as a
A greenhouse gas is simply any atmospheric gas that traps heat within the atmosphere These gases allow sunlight to pass through the atmosphere and reach the earth's surface Some of this sunlightGreenhouse 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 Carbon dioxide, methane, and water vapour are the most important greenhouse gasesGreenhouse effect a theorized change in the earth's climate caused by accumulation of solar heat in the earth's surface and atmosphere Human activity contributes increasing amounts of the socalled greenhouse gases, such as carbon dioxide, methane, and chlorofluorocarbon, to the atmosphere Some of the particles and gases in the atmosphere

The greenhouse effect is a warming of Earth's surface and the air above it It is caused by gases in the air that trap energy from the sun These heattrapping gases are called greenhouse gases The most common greenhouse gases are water vapor, carbon dioxide, and methane Without the greenhouse effect, Earth would be too cold for life to existGreenhouse gases The main greenhouse gases are water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6) Water vapor is the most plentiful at about one percent The next most plentiful is carbon dioxide at 004 percentGreenhouse gas Any of the atmospheric gases that contribute to the greenhouse effect by absorbing infrared radiation produced by solar warming of the Earth's surface They include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor

Greenhouse Effect Wikipedia
warming of the surface and lower atmosphere of a planet (such as Earth or Venus) that is caused by conversion of solar radiation into heat in a process involving selective transmission of short wave solar radiation by the atmosphere, its absorption by the planet's surface, and reradiation as infrared which is absorbed and partly reradiated back to the surface by Greenhouse Gases at EPA Before there were federal requirements to do so, EPA had developed a greenhouse gas (GHG) emissions inventory and established reduction targets to decrease its GHG footprint There are three types of GHG emissions EPA tracks and works to reduce Scope 1 GHG emissions are direct emissions from sources that are owned orChlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are fully or partly halogenated paraffin hydrocarbons that contain only carbon , hydrogen (H), chlorine (Cl), and fluorine (F), produced as volatile derivative of methane, ethane, and propane They are also commonly known by the DuPont brand name Freon

Greenhouse effect, a warming of Earth 's surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapour, carbon dioxide, methane, and certain other gases in the air Of those gases, known as greenhouse gases, water vapour has the largest effect greenhouse effect on Earth The greenhouse effect on EarthWHAT IS THE GREENHOUSE EFFECT The greenhouse effect is a natural phenomenon and is beneficial for us Certain gases in the atmosphere retain part of the thermal radiation emitted by the Earth's surface after being heated by the sun, this maintains the planet's temperature at a level suitable for the development of life Human action, however, has increased the presence of these gasesCarbon dioxide is the most commonly produced greenhouse gas Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide It is one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change
