Answer 1

Hey guys this is Nitish singh

The various routes across the Mountain in the north have provided passages to incident travellers, while the Seas/Oceans restricted such movements for a long period of time.
These routes have contributed the exchange of ideas, commodities and goods since Ancient times. The ideas of the Upanishad, the Ramayana, the stories of Panchtantra, the Indian numerals and the Decimal system thus could reach most parts of the world. The spices, Muslin (a cloth), and other merchandise were taken from India to various Countries in the whole world.

On the other hand, the influence of Greek sculpture, and the Architectural from Dome and Minarets from West Asia can be seen in different parts of our country (India).
