The Tetrahedral Hypothesis of the origin of continents and ocean basin was proposed by
Lowthian Green
The Tetrahedral Hypothesis proposed that the earth's original mass had a tetrahedral shape, which explains the distribution of continents and ocean basins. It was formulated by Lowthian Green in 1875, well before Alfred Wegener's Continental Drift Theory of 1912. F B Taylor and W M Davis are associated with unrelated theories on mountain building and the geographical cycle respectively.
