These are some of the man-made greenhouse gases:
* SF6 (Sulfur hexafluoride) * CFC-11 * CFC-12 * CFC=1113 * Carbon tetrachloride * HCFC-22
The 11 gases that occur naturally in Earth's atmosphere are nitrogen, oxygen, argon, carbon dioxide, neon, helium, methane, krypton, hydrogen, xenon, and ozone. These gases have varying concentrations and play important roles in maintaining the balance of our atmosphere.
CFCs (chlorofluorocarbons) are greenhouse gases that are entirely made by human endeavors. All other greenhouse gases (carbon dioxide (CO2), methane CH4, etc occur in nature as well as being produced by man.
Two elements that commonly occur in nature as liquids are mercury and bromine. Mercury is a naturally occurring liquid metal, while bromine is a non-metallic element that exists as a liquid at room temperature.
The greenhouse effect causes the earth to keep naturally warm. This has gone on for millions of years.The enhanced greenhouse effect happens because humans started burning fossil fuel and cutting down trees. This meant that more carbon dioxide started building up in the atmosphere, too much for the natural carbon cycle to deal with. This extra build up of greenhouse gas is causing global warming.
Volcanic gases escape through a vent called a fumarole or fissure on the surface of a volcano. This release of gases can occur steadily or explosively, depending on the volcanic activity.

The items that occur in nature as uncombined elements are the noble gases. These gases include xenon, helium, radon, argon, neon, and krypton.
Yes, noble gases do not typically form compounds with other elements in nature because of their stable and inert nature. However, some rare exceptions include xenon compounds that have been synthesized in the laboratory but do not occur naturally in the environment.
Gases are made when you heat up solids or liquids. Liquids are made when you cool down gases or heat up solids. Solids are made when you cool down gases or solids. When you heat up solids they make liquids and when you heat up liquids it makes gases. When you heat up gases it makes plasma (plas-mu) but that is very very very very very very hard to make.
During the stage of photosynthesis, the exchange of gases occur in the leaves.
An element occur in nature as a pure element or as a compound.
Bromine is a liquid but doesn't occur in nature as a free element.
Bromine is a liquid but doesn't occur in nature as a free element.
Yes, the halogens did occur in nature as free elements.
Gravity, electromagnetism, friction, and wind are forces that occur in nature. Earthquakes, volcanic eruptions, lightning, and tornadoes are natural phenomena that occur in nature.
Inert gases, also known as noble gases, occur in atomic form because they have a complete valence electron shell, making them chemically stable and unreactive. This full outer shell configuration means they do not readily form bonds with other atoms, leading to their existence as isolated atoms rather than molecules. As a result, they are found in nature primarily as single atoms in the gaseous state.
About 80% of the first 117 elements occur in the nature in a stable manner.
