Continental Drift

Tectonics and Volcanism

The gradual movement of Earth's continents relative to one another across geological time, first proposed as a coherent theory by Alfred Wegener in 1912 from the fit of coastlines and matching fossil and rock records across oceans. It was later explained mechanistically by plate tectonics and seafloor spreading, which showed continents riding passively atop moving tectonic plates rather than plowing through oceanic crust.

  • Road to acceptance, Modern evidence
    By 1967, barely two decades after discovery of the mid-oceanic rifts, and a decade after discovery of the striping, plate tectonics had become axiomatic to modern geophysics.

    Alfred Wegener first presented his hypothesis to the German Geological Society on 6 January 1912.
