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. Web2 days ago · The findings rest on the widely held theory that Earth’s atmosphere was formed by gases released from volcanic activity on its surface. 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. highway 80 web cameras
