The geological processes and degassing processes of the earth are discussed in the article.The author thinks the earth has five gas-spheres al least,such as atmosphere,gas-sphere in the upper crust,gas-sphere in the middle crust,gas-sphere in the upper mantle and gas-sphere in the outer core.Mantle liquid(mantle ichor),which is a complex compound system,is the source of the gas of all gas-spheres in the earth.The gas-sphere in the middle crust has huge natural gas resource.In the author’s opinion that gas.
Key words： Earth; Degassing processes; Gas-sphere; Middle crust; Low velocity zone; Mantle liquid; Mantle ichor.
