The correct option is (b) 2 only.
Explanation
Asia is the largest continent on Earth, covering approximately 30% of the planet's total land area. Its geographical positioning is defined by specific latitudinal and longitudinal extents and natural boundaries separating it from other continents.Statement-wise Analysis:
- Statement 1 is Incorrect. Asia lies almost entirely in the Eastern Hemisphere and the Northern Hemisphere. A small portion of it extends into the Southern Hemisphere (parts of Indonesia), but it does not lie in the Western Hemisphere.
- Statement 2 is Correct. The continent of Asia is separated from Europe in the west by the Ural Mountains and the Ural River. This natural barrier is the primary geographical division between the two landmasses, which are collectively referred to as Eurasia.
- Statement 3 is Incorrect. The Equator does not pass through the center of Asia. Instead, the Equator passes through the southern islands of the continent, specifically through Indonesia and near the Maldives. It is the Tropic of Cancer that passes through the middle of the Asian landmass.
Key Takeaway: Asia is located primarily in the Eastern and Northern Hemispheres, separated from Europe by the Ural Mountains, with the Tropic of Cancer running through its central region and the Equator touching its southern extremities.
