Volcanoes and Earth :: Geology

VOLCANOES AND THE EARTH SYSTEMEFFECTS OF VOLCANIC GASESMost of the gases in the nimbus earlier come from the Earths interior. Gases within magma are dissolved because of high pressures beneath the earths surface, but reduced pressure at the surface allows dissolved gases to expand and escape. When a vol pukeo erupts, gases such as second dioxide, carbon dioxide, chlorine, argon, sulfur, carbon monoxide, fluorine, and pee vapor escape into the atmosphere.Although many of the gases emitted during a vol standic kick groundwork be steadying to the earth, a lot of the gases potty be disruptive to the earth system. Quite possibly the only gas that is generally better for the atmosphere than the rest of the gases is pee vapor. Although it is a glasshouse gas, water vapor from volcanic eruptions adds to the earths water supply. Sulfur dioxide emitted from volcanic eruptions is one of the main chemical compounds responsible for the earths already dangerous unpleasant rain problem . Carbon dioxide is universally considered one of the most dangerous greenhouse gases on the planet. Increases in this gas have been proven to cause an increase in the average temperature of the Earth. Global calefacient can result in the melting of polar ice caps. This melting causes the rising of ocean levels, which can flood coastal cities.Volcanoes contribute about cx million tons of carbon dioxide per year. Although this can be viewed as a bad problem for the ever-increasing problem of global warming, blowholees can actually cause the resistance effect. Volcanoes can help cool the earths surface by forming sulfuric acid aerosols that reflect the suns rays. This is contradicted though by the carbon dioxide that adds to the greenhouse effect.Weather patterns can be disrupted by sulfur dioxide. In a reaction involving the sun and water vapor, sulfur dioxide can turn into sulfuric acid. This sulfuric acid can combine with rain and cause acid rain to fall to earth. Sulfuric aer osol remains in the air desire after the volcano has erupted. These aerosols can last for years and studies have shown a strong correlation between periods of long-term sulfuric aerosol layers in the atmosphere and a resulting temperature decrease during those equal years. Without replenishment, the sulfuric acid aerosol layer around the earth is gradually depleted, but it is renewed by each eruption rich in sulfur dioxide. This was determined after the eruptions of such volcanoes as El Chichon in Mexico and Mt.Volcanoes and Earth GeologyVOLCANOES AND THE EARTH SYSTEMEFFECTS OF VOLCANIC GASESMost of the gases in the atmosphere originally come from the Earths interior.

Global warming can result in the melting of polar ice caps. This melting causes the rising of ocean levels, which can flood coastal cities.Volcanoes contribute about 110 million tons of carbon dioxide per year. Although this can be viewed as a bad problem for the e ver-increasing problem of global warming, volcanoes can actually cause the opposite effect. Volcanoes can help cool the earths surface by forming sulfuric acid aerosols that reflect the suns rays. This is contradicted though by the carbon dioxide that adds to the greenhouse effect.Weather patterns can be disrupted by sulfur dioxide. In a reaction involving the sun and water vapor, sulfur dioxide can turn into sulfuric acid. This sulfuric acid can combine with rain and cause acid rain to fall to earth. Sulfuric aerosol remains in the air long after the volcano has erupted. These aerosols can last for years and studies have shown a strong correlation between periods of long-term sulfuric aerosol layers in the atmosphere and a resulting temperature decrease during those same years.
