Towards understanding how surface life can affect interior geological processes: a non-equilibrium thermodynamics approach [PDF]
, 2011 Life has significantly altered the Earth’s atmosphere, oceans and crust. To what extent has it also affected interior geological processes? To address this question, three models of geological processes are formulated: mantle convection, continental ...
