[5], The planet Venus experienced a runaway greenhouse effect, resulting in an atmosphere which is 96% carbon dioxide, and a surface atmospheric pressure roughly the same as found 900 m (3,000 ft) underwater on Earth. The greenhouse isalso called a “HOT HOUSE” because it gets so hot. This is an example of a greenhouse effect. The glass windows allow light energy from the sun to enter the car. This causesthe earth to warm up. Further information can also be found in Wikipedia. It is nearer to the Sun than Earth by about 30%. The rest of the infrared radiation, the thick red arrow, is absorbed by the greenhouse gases and clouds in the atmosphere and then re-emitted in all directions as shown by the collection of orange arrows. Step 2: The rest of the sun's energy is absorbed by the land and the oceans, heating the Earth.

[22] At these wavelengths, greenhouse gases that were largely transparent to incoming solar radiation are more absorbent. greenhouse effect - warming that results when solar radiation is trapped by the atmosphere; caused by atmospheric gases that allow sunshine to pass through but absorb heat that is radiated back from the warmed surface of the earth This light energy hits things inside the car like the seats and carpet. WHAT IS THE GREENHOUSE EFFECT. [[|]] This increase in radiative forcing from human activity is attributable mainly to increased Most of this thermal radiation is absorbed by the atmosphere and warms it. Because infrared radiation has a different wavelength than solar radiation, its transmission behaviour through the atmosphere is different: 15-30% will be transmitted and 70 to 85% will be reflected back to the Earth. The sun warms the ground and contents inside just like the outside, and these then warm the air. [2] The result, however, is an increase in temperature in both cases. Rather than the surface itself, it is more realistic to think of the greenhouse effect as applying to a layer in the mid-troposphere, which is effectively coupled to the surface by a lapse rate. The heat that isn’t absorbed by plants is trapped by the glass and can’t escape. A greenhouse is constructed of glass, allowing sunlight to penetrate the exterior and warm the air and plants inside. Greenhouse effect: The process of energy absorption and re-radiation by the GHGs in the atmosphere. The 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. [43] A runaway greenhouse effect involving carbon dioxide and water vapor has long ago been hypothesized to have occurred on Venus,[44] this idea is still largely accepted[citation needed]. The greenhouse effect also happens with the entire Earth. Part of this radiation is directed towards the surface, thus warming it. This ability to absorb and re-emit infrared radiation is the critical requirement for greenhouse gases. [19][20] The surface temperature of this hypothetical planet is 33 °C (59 °F) below Earth's actual surface temperature of approximately 14 °C (57 °F). Greenhouse effect. When a body is warmer than its environment, it emits infrared radiation. The atmosphere also gains heat by sensible and latent heat fluxes from the surface. Their effects, together with those of other anthropogenic drivers, have been detected throughout the climate system and are extremely likely to have been the dominant cause of the observed warming since the mid-20th century'".[30]. Though more than 99% of the dry atmosphere is IR transparent (because the main constituents—N2, O2, and Ar—are not able to directly absorb or emit infrared radiation), intermolecular collisions cause the energy absorbed and emitted by the greenhouse gases to be shared with the other, non-IR-active, gases.
