What is the geographical significance of considering Dharwar and Singhbhum ancient rocky regions?
Answer and explanation
Correct answer: They show old mineral-rich terrains of Peninsular India
Option A is correct because the Dharwar and Singhbhum regions represent ancient hard-rock terrains of Peninsular India and are closely associated with mineral resources. Their rocks formed during very early geological periods and have undergone long erosion, weathering, and tectonic changes. The exposed crystalline basement and related formations help explain the occurrence of iron ore, manganese, gold, copper, and other minerals in parts of these regions. They are not coral islands, young alluvial plains, or outer Himalayan ranges. Thus their geographical significance lies in showing the old geological foundation and mineral wealth of the peninsular block.
