What is the greenhouse effect easy definition
What is the greenhouse effect easy definition- The "natural greenhouse effect" (increase of earth temperatures by 33°C) is a myth IRactive gases do not act "like a blanket" but rather "like a sunshade" They keep a part of the solar energy away from the earth's surface " The roots of the greenhouse effect concept lie in the 19th century, when French mathematician Joseph Fourier calculated in 14 that the Earth would be much colder if it had no atmosphere In 16, Swedish scientist Svante Arrhenius was the first to link a rise in carbon dioxide gas from burning fossil fuels with a warming effect

Adding more greenhouse gases to the atmosphere enhances the effect, making Earth's surface and lower atmosphere even warmer Image based on a figure from US EPA ( larger version) Greenhouse gases affect Earth's energy balance and climate The Sun serves as the primary energy source for Earth's climate The greenhouse effect arises from Earth's atmosphere Visible light from the sun , as well as invisible ultraviolet and infrared wavelengths, can penetrate theThen release energy in all directions, which keeps the Earth warm An example of greenhouse gases are carbon dioxide, methane and water vapour Infrared radiation from the Sun is
Many Earth scientists and meteorologists, however, were becoming alarmed about the growing evidence supporting the notion of an enhanced greenhouse effect In 1979 the World Meteorological Organization (WMO) established its World Climate Program to collect data and research the complex components of the Earth's climate systemFigure 71 Rise in the concentrations of greenhouse gases since the 18th century As we will see in section 73, simple theory shows that a rise in greenhouse gases should result in surface warming;The greenhouse effect happens when certain gases—known as greenhouse gases—collect in Earth's atmosphere These gases, which occur naturally in the atmosphere, include carbon dioxide, methane, nitrogen oxide, and fluorinated gases sometimes known as chlorofluorocarbons (CFCs) Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere
The greenhouse effect The exchange of incoming and outgoing radiation that warms the Earth is often referred to as the greenhouse effect because a greenhouse works in much the same way Incoming UVThe greenhouse effect causes some of this energy to be waylaid in the atmosphere, absorbed and released by greenhouse gases Without the greenhouse effect, Earth's temperature would be below freezing It is, in part, a natural process However, Earth's greenhouse effect is getting stronger as we add greenhouse gases to the atmosphere Weather is a specific event—like a rainstorm or hot day—that happens over a few hours, days or weeks Climate is the average weather conditions in a place over 30 years or more NASA has observed that Earth's climate is getting warmer

Chapter 7 The 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 An amplified greenhouse effect is driving the changes, according to Myneni Increased concentrations of heattrapping gasses, such as water vapor, carbon dioxide and methane, cause Earth's surface, ocean and lower atmosphere to warm Warming reduces the extent of polar sea ice and snow cover, and, in turn, the darker ocean and land surfacesThe 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 exist

Greenhouse Effect The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is reradiated in all directions Since part of this reradiation is back towards the surface and the lower atmosphere, it results in an elevation of the average surface temperature aboveGreenhouse Earth Overview of greenhouse Earth A "greenhouse Earth" is a period in which there are no continental glaciers whatsoever on the planet Additionally, the levels of carbon dioxide and other greenhouse gases (such as water vapor and methane) are high, and sea surface temperatures (SSTs) range from 28 °C (4 °F) in the tropics to 0 °C (32 °F) in the polar regionsGreenhouse effect, a warming of Earth's surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapor, carbon dioxide, methane, and certain other gases in the air Of those gases, known as greenhouse gases,

The retention of part of the Sun's energy in the Earth's atmosphere in the form of heat as a result of the presence of greenhouse gases Solar energy, mostly in the form of shortwavelength visible radiation, penetrates the atmosphere and is absorbed by the Earth's surface The greenhouse effect is a good thing It warms the planet to its comfortable average of 59 degrees Fahrenheit (15 degrees Celsius) and keeps life on earth, well, livable Without it Earth as a closedup greenhouse would soon grow to be ghastly!

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere Radiatively active gases (ie, greenhouse gases) in a planet's atmosphere radiate energy in all directionsIn bright sunshine, the air inside a greenhouse becomes warm The greenhouse glass lets in the sun's light energy and some of its heat energy This heat builds up inside the greenhouse You just showed a small greenhouse effect What could happen if this greenhouse effect changed the Earth's climate? Some climate change skeptics dispute the socalled 'greenhouse effect', which keeps the surface temperature of the Earth approximately 33 degrees C warmer than it would be if there were no greenhouse gases in the atmosphere In other words, without the greenhouse effect, the Earth would be largely uninhabitable

The greenhouse effect is the way in which heat is trapped close to the surface of the Earth by "greenhouse gases" These heattrapping gases can be thought of as a blanket wrapped around the Earth, which keeps it toastier than it would be without them Greenhouse gases include carbon dioxide, methane and nitrous oxidesDescribes how greenhouse gases, such as carbon dioxide, methane, and water vapor, trap heat in the atmosphere, and that levels of these gases are increasing due to human activities Concept Map Discover related concepts in Math and Science CK12 Content Community ContentGreenhouse 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

In short it is the natural process that warms the Earth's surface The process is called the greenhouse effect because the exchange of incoming and outgoing radiation that warms the planet works in a similar way to a greenhouse The greenhouse effect happens when these gases gather in the Earth's atmosphere According to scientists, without the greenhouse effect, the average temperature of the Earth would drop from 57 degrees Fahrenheit (14 degrees Celsius) to as low as negative 04 degrees F (minus 18 degrees C) Do We Blame the Industrial Revolution?Earth's natural greenhouse effect Earth's temperature begins with the Sun Roughly 30 percent of incoming sunlight is reflected back into space by bright surfaces like clouds and ice Of the remaining 70 percent, most is absorbed by the land and ocean, and the rest is absorbed by the atmosphere The absorbed solar energy heats our planet
