Continental drift plate tectonics theory. In particular, the English geologist Arthur Holmes proposed in 1920 that plate junctions might lie beneath the sea, and in 1928 that convection currents within the mantle might be the driving force. Holmes' views were particularly influential: in his bestselling textbook, "Principles of Physical Geology," he included a chapter on continental drift, proposing that Earth's mantle contained convection cells which dissipated radioactive heat and moved the crust at the surface. Holmes' proposal resolved the phase disequilibrium objection (the underlying fluid was kept from solidifying by radioactive heating from the core). However, scientific communication in the '30 and

In the years between "Tilt" and "The Drift", Walker's released output comprised a few instrumental tracks on the soundtrack to the film "Pola X", a cover of Bob Dylan's "I Threw It All Away" on the "To Have and to Hold" soundtrack, and "Only Myself to Blame" from "The World Is Not Enough" soundtrack, as well as a few compilations of previously released material, including the retrospective box set "5 Easy Pieces". "The Drift" has been cited by many
