How seafloor spreading affect the environment
NettetThe seafloor spreading hypothesis was proposed by the American geophysicist Harry H. Hess in 1960. On the basis of Tharp’s efforts and other new discoveries about the deep … NettetThe study was conducted near Norway’s Svalbard Islands, above several seafloor methane seeps. Methane is a more potent greenhouse gas than carbon dioxide, but the removal of carbon dioxide from the atmosphere where the study was conducted more than offset the potential warming effect of the methane emissions that were observed.
