Asia Asia is the Earth 's largest and most populous continent, located primarily in the eastern and northern hemispheres. It covers 8.8% of the Earth 's total surface area and comprises 30% of its land area, and has the largest coastline, at 62,800 kilometres (39,022 mi). Asia is generally defined as comprising the eastern four-fifths of Eurasia. Asia is subdivided into 48 countries, two of them (Russia and Turkey) having part of their land in Europe. With approximately 4.427 billion people, it hosts 60% of the world 's current human population. Like most of the world, Asia has a high growth rate in the modern era. For instance, during the 20th century, Asia 's population nearly quadrupled, as did the world population. The boundaries of Asia are culturally determined, as there is no clear geographical separation between it and Europe, which together form one continuous landmass called Eurasia.

It is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean and on the north by the Arctic Ocean. Given its size and diversity, the concept of Asia – a name dating back to classical antiquity - may actually have more to do with human geography than physical geography. Asia varies greatly across and within its regions with regard to ethnic groups, cultures, environments, economics, historical ties and government systems.
Climate Zones of Asia The Climate of Asia is wet across southeast sections and dry across much of the interior. Some of the largest daily temperature ranges on Earth occur in western sections of Asia. The monsoon circulation dominates across southern and eastern sections, due to the presence of the Himalayas forcing the formation of a thermal low
