Correct Option
The correct option is (a).
Explanation
Asia is the largest continent on Earth, comprising a significant portion of the global landmass. Its geographical extent covers the Eastern and Northern Hemispheres, defined by distinct physical boundaries and latitudinal positions.
Statement-wise Analysis
- Statement 1 is Correct: Asia is the largest continent in the world. It covers approximately one-third of the total land area of the Earth. It lies primarily in the Eastern Hemisphere.
- Statement 2 is Incorrect: The Equator does not pass through the center of the Asian continent. The Equator passes through the southern islands of Asia (such as Indonesia and Maldives), but the main continental landmass lies entirely to the north of the Equator. The Tropic of Cancer passes through the middle of the continent.
- Statement 3 is Incorrect: Asia is separated from Europe by the Ural Mountains on the west. The Andes Mountains are located in South America, running along its western coast.
Key Takeaway
Asia is the largest continent, covering one-third of Earth's land area. It is separated from Europe by the Ural Mountains, and the Tropic of Cancer runs through its central region, not the Equator.
