🌍 WORD OF THE DAY — ANTECEDENT DRAINAGE

क्या आपने सोचा है कि mountains के uplift होने के बावजूद कुछ rivers अपना पुराना course कैसे बनाए रखती हैं?

Antecedent Drainage = ऐसी नदी जो land uplift होने से पहले मौजूद थी और uplift के दौरान लगातार downcutting करके अपना original course बनाए रखती है।

📌 Etymology: Ante = पहले + Cedere = आगे बढ़ना
📌 Scholar: J. W. Powell — 1875
📌 Importance: यह concept tectonic uplift और river erosion के relationship को समझने में important है, especially Himalayan drainage के context में।

🎯 Memory Trick: “River पहले, uplift बाद में!”
