EFFECTS OF CONTINENTAL DRIFT
Most of the relief features are related with continental drift due to the fact that forces such as tensional and compression forces affected many parts of the world. Features which have been formed as a result of continental drift include; rift valleys, basins, plateau, highland ranges, coastal plains and associated features, block mountains etc. A rift valley is one of the spectacular features associated with continental drift. This is an elongated depression bordered by two in facing escarpments. It is formed due to either compressional forces or tensional forces or through differential uplift theory, basin and swell theory and the sea floor spreading theory. Plate tectonics also caused the vertical movement of the crust which led to the formation of Block Mountains. A block mountain is also known as a Horst. It is formed when the middle block bounded by more or less parallel faults is made to rise or is uplifted by the compressional forces. The best example of a block mountai...
