There are seven continents:
Asia is the largest of all continents. It lies mostly in the northern hemisphere. Pacific Ocean in the east, Arctic Ocean in the north and Indian Ocean in the south surrounded this landmass. Asia has rich cultural as well as physical diversity. It has highest point on the earth i.e. the Mount Everest in Nepal and the lowest point on land i.e. the Dead Sea near Jordan.
It has the world’s two most populous countries: India ,china.
Great civilizations have flourished along the banks of river Yangtze in china and the Indus and the Ganga in the Indian subcontinent. Is also has one of the hottest and the coldest deserts namely the tar and Gobi desert respectively.
