ESS102H1 Lecture Notes - Expanding Earth, Science North, Seafloor Spreading
Document Summary
Physics professors at uoft (1946-1974) founder of science north in sudbury first non-american president of agu (agu altered its constitution to allow this) in a 1960 paper wilson argued in favour of expanding earth . The foregoing hypothesis has the merit of appearing to explain many features of the earth"s surface, though this does not constitute a proof. Matching observations/consequences high-heat flow at mid-ocean ridges (mor) shallow earthquakes at mor buckling of earth away from mor (distance to mor may be necessary condition) Lab 1946-1963 geology professor at arizona state from 1977-85 helped develop bathyscaph trieste that in 1960 dived into the 11km. The concept proposed here [] is largely intuitive [] while the thought of a highly mobile sea floor may seem alarming at first, it does little violence to geologic history. Mechanism: ocean ridges: high heat flow at ridges: fit of continents:
