How are atmospheres formed
WebThere seem to be two types of atmospheres: original ones, formed from gas present in the primordial dust cloud, and evolved or outgassed ones, whose gases have gradually come out of the interior of the planet, probably as the result of volcanism. The atmospheres of the gas giant planets are largely original. WebThe planets are orbiting the Sun, formed by accretion. The heavier elements concentrated in the cores, and the lighter gaseous elements became the atmospheres. The most abundant chemical elements in the Sun are hydrogen, 73.5%, and helium, 24.9%. All other elements are in concentrations of less than one percent.
