Which combined base was most necessary on Earth before origin of life?

Answer and explanation

Correct answer: Stable surface, liquid water, suitable chemicals and a favourable atmosphere

The origin of life required several favourable conditions together: a stable surface, liquid water, essential chemicals such as carbon compounds, and a suitable atmosphere. Liquid water provided a medium for chemical reactions, while the atmosphere supplied useful gases and protection. A metallic core alone is part of Earth’s internal structure, but it could not by itself support the origin of life. Exam tip: remember liquid water, suitable chemicals and a favourable atmosphere as linked conditions for life’s origin.
