what initially shaped earth’s early atmosphere?\no tornadoes\no respiration of annelids\no photosynthesis of…

Brief Explanations:

Early in Earth's history, volcanic outgassing released gases like water vapor, carbon - dioxide, and nitrogen which formed the early atmosphere. Tornadoes are weather events that occur much later in Earth's history and are not related to the formation of the early atmosphere. Annelids are relatively complex organisms that evolved long after the early atmosphere was formed, so their respiration did not shape the early atmosphere. Land plants also evolved later and their photosynthesis was not responsible for the initial shaping of the atmosphere.

Answer:

outgassing of volcanoes
