Final answer:

The atmosphere of the early Earth primarily consisted of water vapor, carbon dioxide, nitrogen, and sulfur, with no oxygen initially. Plant life later introduced oxygen through photosynthesis, shaping the Earth's current atmosphere.


Explanation:

The atmosphere of the early Earth is thought to have contained water vapor, carbon dioxide, nitrogen, and sulfur among other gases, but no oxygen was present initially. As the planet cooled and formed a solid crust, volcanoes released gases that contributed to the formation of the early atmosphere. Over time, the primitive forms of plant life began to release oxygen into the atmosphere through photosynthesis, leading to the evolution of our current oxidizing atmosphere.
