For Wegener the drifting mechanism was the most difficult question to solve. He tried to attribute the westward drift of the Americas to feeble lunar-solar drag.
- Geologists also raised question about the exact fitting of the opposing coasts of Atlantic. It was also assumed that approximate fit of the continents may be a coincidence created by erosion process. His theory was vehemently rejected by American geologists.

Plate Tectonics
Historical Background
The fair idea about continental drift theory given by Alfred Lothar Wegener. Wegener delivered a lecture on “The Formation of the major Features of the Earth՚s Crust (Continents and Oceans) ” at Frankfurt in an eminent Geological Association. In his lecture he suggested that continents had once been combined in the form of original single sialic land-mass and had afterward broken apart and drifted to their prese…
