Elaborate continental drift theory. |
Answer» \tContinental drift theory was proposed by Alfred Wegener in 1912.\tIt was first put forward by Abraham Ortelius in 1596 before fully being developed by Alfred Wegener.\tThe theory deals with the distribution of the oceans and the continents.\tAccording to Wegener’s Continental Drift theory, all the continents were one single continental mass (called a Super Continent) – Pangaea and a Mega Ocean surrounded this supercontinent. The mega ocean is known by the name Panthalassa.\tAlthough Wegener’s initial theory did not cover mantle convection until Arthur Holmes later proposed the theory.\tThe supercontinent was named Pangaea (Pangea) and the Mega-ocean was called Panthalassa.\tAccording to this theory, the supercontinent, Pangaea, began to split some two hundred million years back.\tPangaea first split into 2 big continental masses known as Gondwanaland and Laurasia forming the southern and northern modules respectively.\tLater, Gondwanaland and Laurasia continued to break into several smaller continents that exist today. | |
