What is the difference between the greenhouse effect and photosynthesis?

Answer 1

The greenhouse effect is a natural process that keeps the Earth warm. Without it, the earth would be unable to retain enough heat to sustain life.

The enhanced greenhouse effect is caused by the all the extra greenhouse gases (carbon dioxide, methane etc) that we put into the air from burning fossil fuels and agriculture (cattle belches). These all trap more heat and radiation from the sun than is normally required. The earth radiates infrared energy from the sunlight that reaches the surface which should escape off into space, but due to the enhanced greenhouse effect, this radiation is trapped. Therefore, the overall temperature of the globe rises.

See this link below for a diagram:
Global warming is the increase of the average temperature of the earths atmosphere due to the greenhouse effect. The greenhouse effect is caused by high concentrations of methane, co2 and water vapour in the earth's atmosphere . These gases occur naturally (natural greenhouse effect) however due to human activity (cars, burning fossil fuels, deforestation) more of these gases are released, and this enhances the greenhouse effect (so it is called the enhanced greenhouse effect.)

Answer 2

The Greenhouse effect refers to the change in the thermal equilibrium temperature of a planet or moon by the presence of an atmosphere containing gas that absorbs infrared radiation.[1] Greenhouse gases, which include water vapor, carbon dioxide and methane, warm the atmosphere by efficiently absorbing thermal infrared radiation emitted by the Earth's surface, by the atmosphere itself, and by clouds. As a result of its warmth, the atmosphere also radiates thermal infrared in all directions, including downward to the Earth's surface. Thus, greenhouse gases trap heat within the surface-troposphere system.[2][3][4][5] This mechanism is fundamentally different from the mechanism of an actual greenhouse, which instead isolates air inside the structure so that heat is not lost by convection and conduction, as discussed below. The greenhouse effect was discovered by Joseph Fourier in 1824, first reliably experimented on by John Tyndall in the year 1858 and first reported quantitatively by Svante Arrhenius in his 1896 paper.[6] In the absence of the greenhouse effect, the Earth's average[7] surface temperature of 14 °C (57 °F) would be about -18 °C (-0.4 °F), the Black body temperature of the Earth [8]. Anthropogenic global warming (AGW), a recent warming of the Earth's lower atmosphere as evidenced by the global mean temperature anomaly trend [9], is believed to be the result of an "enhanced greenhouse effect" mainly due to human-produced increased concentrations of greenhouse gases in the atmosphere[10] and changes in the use of land[11]. The greenhouse effect is one of several factors which affect the temperature of the Earth. Other positive and negative feedbacks dampen or amplify the greenhouse effect.

Answer 3

Greenhouse effect: getting carbon derivatives out of the earth, burning it and putting it into the air as carbon dioxyde. This increases the amount of carbon dioxyde in the air. photosynthesis. Plants can absorb carbon dioxyde from the air, transforming it into carbon derivatives. Plants need light to do that. When the plant dies or when it is burned, the carbon dioxyde is released again into the air. So a plant or a forest cannot reduce the amount of CO2 in the air. The only way to do that is cutting a tree and putting it into the ground. If the oxygen cannot reach the tree, the CO2 cannot be released.
