Natural History of Indian subcontinent

Which river originates from Deccan Plateau?

Rivers originating from Deccan Plateau are primarily peninsular east-flowing rain-fed systems sourced in Western Ghats escarpment forming western boundary of Deccan. Godavari originates near Trimbakeshwar Nashik, Krishna at Mahabaleshwar, Cauvery at Talakaveri Brahmagiri, all draining basalt plateau into Bay of Bengal forming fertile deltas. These contrast with Himalayan rivers Ganga, Yamuna, Brahmaputra originating from Himalayan glaciers perennial. Deccan rivers ephemeral dependent on monsoon 600-1500 mm rainfall, essential for irrigation agriculture in semi-arid plateau despite seasonal flow variation. Such details are high-yield for NEET and CUET as they link morphological classification with modern molecular phylogeny insights.

Black soil of Deccan plateau is best suited for

Black soil of Deccan plateau, regur, formed by basalt weathering, possesses high clay content predominantly montmorillonite conferring superior moisture retention for months after monsoon, rich in calcium carbonate, potash, lime, yet poor nitrogen. Texture fine, cracks deep in summer facilitating self-ploughing. Cotton Gossypium requires long frost-free period, moderate water, black soil ideal as it retains moisture and supports deep taproot. Maharashtra Vidarbha and Marathwada cotton belts exemplify correlation, producing majority Indian cotton export due to regur fertility properties. Mastery of this rule helps candidates differentiate closely related categories and avoid common errors in diversity questions.
