What era was when earth's atmosphere formed?
The Earth's atmosphere began to form around 4.5 billion years ago during the Hadean era, which followed the formation of the Earth itself. Initially, it consisted of gases emitted by volcanic activity and impacts from comets. Over time, the atmosphere evolved through processes like outgassing and the development of photosynthetic life forms.
