Scientists infer that most of Earth earliest atmosphere was produced by the escape of gases from Earth's molten surface. Once these gases were released from the very hot surface that covered the Earth, the earliest stages and levels of the atmosphere we know today were created. Many of those earliest gases still make up our atmosphere today
Explanation:
Earth shaped through a method of accretion -collision of rocks and dirt particles, that step by step shaped a bigger and bigger object. These impacts generated loads of warmth, therefore early Earth would are a hot and desolate place. Vapour is assumed to own shaped a steam atmosphere, and incoming iron-rich rocks colliding with Earth would have reacted with a number of this water to provide rise to H gas.
