A new study explores how the next Pangea could affect the global sp.info Understanding the long-term carbon-cycle:weathering of Jul 07, 2013 · Why a carbon-sink? Because, via weathering of rocks and reprecipitation of weathering products as carbonate sediments (e.g. limestones), huge quantities of atmospheric carbon dioxide end up locked away for a very, very long time.

Volcanic activity and collisions with meteorites and comets added water vapor, carbon dioxide (CO 2), and nitrogen to the atmosphere. As the Earth cooled enough for liquid water to form, the vapor formed clouds from
