How the early atmosphere was formed
NettetFor instance, geologists now think the early atmosphere was not reducing, and it's unclear whether pools at the edge of the ocean are a likely site for life's first appearance. But the basic idea – a stepwise, spontaneous formation of simple, then more complex, then self-sustaining biological molecules or assemblies – is still at the core of most … Nettethow the Earth was originally formed. Explain why the atmosphere makes life on Earth possible. Compare the atmosphere in the first billion years to the present atmosphere. STRETCH: Explain why life isn’t possible on Venus and Mars, and suggest what we would need to do if we wanted to live there. KEY WORDS:
