B
Explanation
The Tetrahedral Hypothesis was proposed by Lowthian Green in 1875 to explain the distribution of continents and ocean basins. The theory is based on the geometric principle that a sphere, when contracting, tends to take the shape of a tetrahedron, which has the minimum volume for a given surface area. According to Green, the four vertices of the tetrahedron represent the stable landmasses (shields), while the flat or concave faces represent the ocean basins.
This hypothesis explains characteristics like the antipodal arrangement of land and water and the triangular shape of continents. Other options are incorrect because:
- F.B. Taylor and Alfred Wegener are associated with the Continental Drift Theory.
- W.M. Davis is renowned for the 'Geographical Cycle' or 'Cycle of Erosion' in geomorphology.
