GEOLOGY

Detailed explanation-1: -The correct answer is : Paleomagnetism. Paleomagnetism was not used by Wegener to bolster his theory of continental drift. Explanation : German scientist Alfred Wegener (1880–1930) was an expert in climatology and meteorology.

Detailed explanation-2: -Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.

Detailed explanation-3: -The four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones’ locations.
