文摘During Earth’s 4.6 billion-year history,its surface has experienced environmental changes that drastically impacted habitability.The changes have been mostly attributed to near-surface processes or astronomical events with little consideration of Earth’s deep interior.Recent progresses in high-pressure geochemistry and geophysics,however,indicate that deep Earth processes may have played a dominant role in the surface(Mao and Mao,2020).
