A Journey To The End Of The Earth

Question
CBSEENEN12020125

How did the globe acquire the present shape?

Solution

The earth was an amalgamated supercontinent in the beginning say about six hundred million years ago. It was called Gondwana. It was the most coldest, windiest and the driest continent in the world. The climate at that time was warm and not suitable for the human life to exist. There were no human markers except a huge variety of flora and fauna. It was the stage when dinosaurs were wiped out and the age of mammals started.

After 500 million years, the landmass was forced to separate into countries as they exist today. Slowly, the climate started changing and drifts started occurring on the surface of the earth. It further deepened to separate various parts of the earth from each other to form countries and continents. With the rapid expansion of huge population, villages, towns, cities and megacities came into existence. Buckling of the crusts against each other gave rise to huge mountains like Himalayas and various water bodies like oceans and rivers. Drifting of American continent gave rise to circumpolar currents, which desolated the polar regions of the earth and making them the coolest places on the earth and thus gave the present shape to the earth.
