the greenhouse effect is defined as?
240390
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.

The greenhouse effect is the trapping of heat under the atmosphere, which is a natural effect caused by greenhouse gases. ... However, when greenhouse gas concentrations are too high, they trap too much heat and increase the temperature on Earth, causing the enhanced greenhouse effect.
754450
The enhanced greenhouse effect is the increasing amount of greenhouse gases in the atmosphere as a result of human activities, while on the other hand, global climate change is the change in the global pattern of climate precipitation, temperature, winds, and pressure systems.

A greenhouse gas is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. ... nitrogen( N2)and oxygen (O2), and argon(Ar), are not greenhouse gases because molecules containing two atoms of the same element.

The major greenhouse gases are water vapor, which causes about 36-70% of the greenhouse effect on Earth (not including clouds); carbon dioxide, which causes 9-26%; methane, which causes 4-9%, and ozone, which causes 3-7%.

['Since green house gases helps to maintain the temperature, the primary effect of the increase in greenhouse gases would be on climate. ... ', 'Water level balance of the earth would be destroyed. ... ', 'Marine life and ecosystem would be destroyed.']

Climate change is a major threat to the health of our planet. Air pollution is closely linked but they are usually treated as separate problems. Rising levels of C02 and other air-polluting gases increase the greenhouse effect, which in turn raises temperatures and affects global weather patterns.
100235
Photosynthesis reduces the affect of global warming. Global warming is a result of gases such as carbon dioxide in the atmosphere absorbing and also trapping radiation which leads to increased temperatures.

Carbon dioxide causes about 20 percent of Earth's greenhouse effect; water vapor accounts for about 50 percent; and clouds account for 25 percent. ... Likewise, when carbon dioxide concentrations rise, air temperatures go up, and more water vapor evaporates into the atmosphere—which then amplifies greenhouse heating.

Enhanced greenhouse effect The problem we now face is that human activities – particularly burning fossil fuels (coal, oil and natural gas), agriculture and land clearing – are increasing the concentrations of greenhouse gases. This is the enhanced greenhouse effect, which is contributing to warming of the Earth.

Greenhouse gases are those that absorb and emit infrared radiation in the wavelength range emitted by Earth. Carbon dioxide (0.04%), nitrous oxide, methane and ozone are trace gases that account for almost one tenth of 1% of Earth's atmosphere and have an appreciable greenhouse effect.
512532
The man-made (or anthropogenic) component of the greenhouse effect is caused by man's activities that emit greenhouse gases to the atmosphere. ... Fossil fuels contain carbon, and when they are burnt this carbon combines with oxygen in the atmosphere to form carbon dioxide.

The greenhouse effect works much the same way on Earth. Gases in the atmosphere, such as carbon dioxide, trap heat just like the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases. ... But some of the heat is trapped by the greenhouse gases in the atmosphere.

Greenhouse gases are certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) that trap energy from the sun. Without these gases, heat would escape back into space and Earth's average temperature would be about 60º F colder.
796142
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). Greenhouse gases have different chemical properties and are removed from the atmosphere, over time, by different processes.

A greenhouse gas (or GHG for short) is any gas in the atmosphere which absorbs and re-emits heat, and thereby keeps the planet's atmosphere warmer than it otherwise would be. The main GHGs in the Earth's atmosphere are water vapour, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and ozone.

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 (i.e., greenhouse gases) in a planet's atmosphere radiate energy in all directions.
