sphere,” combined with the Greek word “lithos” which means rock. The entire outer layer of the Earth on which the continent and ocean are situated is called the lithosphere. On the earth surface, 29% is land and 71% is water. The total area of the entire earth is 5100 million square kilometers. We will see the details about The Lithosphere: Angaraland & Gondwana Land in this article. A Geophysicist and meteorologist, Alfred Wagoner presented the idea of continental drift in 1912. The theory of continental drift related to the origin of continents and oceans.
This idea has been subsumed by the theory of Plate Tectonics.Click here to read about Earth Structure

Its southern part was “Angaraland” and Peninsular India was part of “Gondwana Land“.The current continent and the ocean were created due to the collapse of the Pangaea and the different forces of gravity and flotation.]]>
