Which region is NOT part of the outer boundary of the Peninsular Plateau?

Correct option is D

The correct answer is (d) Himalayas

Explanation:

• The Peninsular Plateau is a large, stable landmass in India that is part of the oldest land formations, primarily composed of igneous and metamorphic rocks.
• Its outer boundary includes regions like the Delhi Ridge (northwest), Rajmahal Hills (northeast), and Gir Range (west).
• The Himalayas, however, are not part of the Peninsular Plateau. They lie to the north and are part of the young fold mountains formed by the collision of the Indian and Eurasian tectonic plates.
• The Peninsular Plateau is bounded by these outer hills and ridges but not by the Himalayas.
• The Himalayas are geologically distinct and younger compared to the ancient Peninsular Plateau.

Information Booster:

• The Peninsular Plateau includes features like the Deccan Plateau, Malwa Plateau, and Chotanagpur Plateau.
• It is rich in mineral resources and is one of the most stable geological formations in India.
