Today, as during the earliest days of the Earth, magma flowing from deep in the Earth contains dissolved gases. When that magma nears the surface, those gases are released into the surrounding air.
WebBelow is an overview of materials that make their way from volcanic eruptions into the atmosphere: particles of dust and ash, sulfur dioxide, and greenhouse gases like water vapor and carbon dioxide. Particles of Dust and Ash Volcanic ash or dust released into the atmosphere during an eruption shade sunlight and cause temporary cooling. Webpressure from below. This can occur if the bulk gas in the upper atmosphere is a good absorber of ultraviolet light and the heated air flows en masse. Unlike Jeans’ case, the bulk atmosphere is no longer static. The atmosphere flows, accelerates smoothly through the sound speed, and then attains the escape speed and higher.
