Continental glaciers expanded atop mountain ranges formed during assembly of Rodinia. b. Weathering of carbonate sediments deposited in warm marine rift basins released CO2 to the atmosphere. c. Widespread basaltic lavas, erupted during rifting of Rodinia, weathered and removed CO2 from the atmosphere. d. Microbial life flourished in warm marine rift basins during Rodinia breakup and removed CO2 from the atmosphere.
