Atmosphere The atmosphere is the vast gaseous envelope of air that surrounds the Earth. Its boundaries are not easily defined.
Carbon Dioxide Common gas found in the atmosphere. It has the ability to selectively absorb radiation. This absorption causes the greenhouse effect. The concentration of this gas has been steadily increasing in the atmosphere over the last three centuries due to the burning of fossil fuels, deforestation, and land-use change. Some scientists believe higher concentrations of carbon dioxide and other greenhouse gases will result in an enhancement of the greenhouse effect and global warming. The chemical formula for carbon dioxide is CO2.
Decomposition (1) To chemically or physically breakdown a mass of matter into smaller parts or chemical elements. (2) Breakdown of organic matter into smaller parts or inorganic constituents by decomposing organisms.
Lithosphere Is the solid inorganic portion of the Earth (composed of rocks, minerals, and elements). It can be regarded as the outer surface and interior of the solid Earth.
