Continental Drift Theory

✅Continental drift theory was proposed by Alfred Wegener in 1912.  

✅It was first put forward by Abraham Ortelius in 1596 before fully being developed by  

Albert Wegener.  

✅ The theory deals with the distribution of the oceans and the continents.  

✅ According 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.  

✅ Although Wagners initial theory did not cover mantle convection until Arthur Holmes later proposed the theory.  

✅The supercontinent was named Pangaea and the Mega-ocean was called Panthalassa.  

✅According to this theory, the supercontinent, Pangaea, began to split some two hundred  

million years back.  

✅Pangaea first split into 2 big continental masses known as Gondwanaland and Laurasia  

forming the southern and northern modules respectively.  

✅Later, Gondwanaland and Laurasia continued to break into several smaller continents that exist today.
