Explanation:

Asia is the most extensive and most populated continent on Earth. With nearly 45 million km², it accounts for 8.70% of the total land area and 29.45% of the land and, with around 1.440 million inhabitants, 69% of the world population. It extends over the eastern half of the Northern Hemisphere, from the Arctic Glacial Ocean, to the north, to the Indian Ocean, to the south. It limits, to the west, with the Ural mountains, and to the east, with the Pacific Ocean.

In the conventional division of continents, of European origin, Asia and Europe appear as two different entities for cultural and historical reasons. In geographical terms, they actually form a single continent, called Eurasia. In addition, Africa is linked to Eurasia by the Isthmus of Suez so it can also be considered the entire joint extension of Europe, Asia and Africa as a single supercontinent, occasionally called Eurafrasia, or Afro-Eurasia.
