what are sinks of greenhouse gases?
153762
Just as trees and vegetation are sources of atmospheric carbon dioxide when they decay, they are a sink for carbon dioxide as they grow. During photosynthesis, trees and vegetation absorb CO2 from the air and emit oxygen. Humans can also add to this carbon sink through such efforts as reforestation.

Much of the CO2 dissolved into the oceans. Eventually, a simple form of bacteria developed that could live on energy from the Sun and carbon dioxide in the water, producing oxygen as a waste product. Thus, oxygen began to build up in the atmosphere, while the carbon dioxide levels continued to drop.

The direct greenhouse gases are carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4). The indirect greenhouse gases are non-methane volatile organic compounds (NMVOCs), nitrogen oxides (NOx) comprised of nitrogen monoxide (NO) and nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon monoxide (CO).

Greenhouse 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 gases.

Greenhouse gases that occur both naturally and from human activities include water vapor, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and ozone (O3).

carbon dioxide, methane, water vapor, & some other atmospheric gases. Explain how greenhouse gases help the range of Earth's temperatures remain stable. These gases let sunlight hit Earth's surface, where it becomes heat energy; trapping that heat energy helps maintain our temperature range.

The major greenhouse gases are water vapor, carbon dioxide (CO2), methane (CH4), chlorofluorocarbons (CFCs) and hydrogenated chlorofluorocarbons (HCFCs), tropospheric ozone (O3), and nitrous oxide (N2O).
642748
Of the greenhouse gases, carbon dioxide (CO2) is the most prominent.

How is the hydrosphere changing? Human contributions to greenhouse gases in the atmosphere are warming the earth's surface - a process which is projected to increase evaporation of surface water and accelerate the hydrologic cycle. In turn, a warmer atmosphere can hold more water vapor.

Forest carbon is released when trees burn or when they decay after dying (as a result of old age or of fire, insect attack or other disturbance). A forest is considered to be a carbon sink if it absorbs more carbon from the atmosphere than it releases. Carbon is absorbed from the atmosphere through photosynthesis.

The main gases emitted by agricultural activities are: Conversely, agriculture helps slow climate change by storing carbon on agricultural lands. Storing, or sequestering, carbon in soil as organic matter, perennial vegetation, and in trees reduces carbon dioxide amounts in the atmosphere.

The carbon cycle is the cycle of carbon being absorbed and then released by plants, the oceans, and other sources and sinks. The nitrogen cycle is the cycle of nitrogen being absorbed and then released by plants, the oceans, and other sources and sinks.

Greenhouse effect However some gases in the atmosphere, called greenhouse gases , trap escaping thermal energy. This causes some of the thermal energy to pass back to the surface. This is called the greenhouse effect , and it keeps our planet warm. Carbon dioxide is an important greenhouse gas.

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.

Gases which contributes in greenhouse effect are carbon dioxide, methane, nitrous oxide, ozone, water vapour, Chlorofluorocarbons (CFCs) and, Hydrofluorocarbons (HCFCs and HFCs). Hydrogen is not a greenhouse gas. Hence, the correct answer is 'Hydrogen'.
