Which region of the Northern Plains is made of older alluvium?
उत्तरी मैदान का कौन – सा क्षेत्र पुराने जलोढ़ से बना है?
Detailed Solution & Logic
भांगर / Bhangar
📘 Explanation
The Northern Plains of India are formed by sediments deposited by rivers flowing from the Himalayas.
Bhangar (भांगर) is the older alluvium, lying slightly above the floodplains.
It contains kankar (lime) nodules and is less fertile than the newer Khadar deposits.
Other regions:
Khadar – new, fertile alluvium found in low-lying floodplains.
Bhabar – a narrow belt of coarse sediments at the Himalayan foothills.
Terai – marshy area with waterlogged soils formed from Bhabar seepage.
भारत के उत्तरी मैदान हिमालय से बहकर आने वाली जलोढ़ मिट्टी से बने हैं।
भांगर पुराने जलोढ़ क्षेत्र को कहते हैं। यह बाढ़ के मैदानों से थोड़ा ऊँचा होता है और इसमें अक्सर कंकर (चूना) के छोटे गोले पाए जाते हैं।
यह क्षेत्र खादर के मुकाबले कम उर्वर है।
अन्य क्षेत्र:
खादर – नदी के पास नया और उर्वर जलोढ़।
भाबर – पहाड़ों के तल में मोटे कणों वाला संकरे क्षेत्र।
तराई – पानी से भरा और दलदली क्षेत्र।
⭐ Extra Facts / अतिरिक्त तथ्य
✅ Bhangar soil supports crops like wheat, pulses, and sugarcane.
✅ भांगर मिट्टी में गेहूं, दाल और गन्ना की खेती होती है।
✅ Kankar nodules form hard layers known as Kankar Bed in Bhangar.
✅ भांगर में कंकर की परत को “कंकर बेड” कहा जाता है।
✅ The thickness of Bhangar deposits usually ranges from 1 to 3 meters.
✅ भांगर की मोटाई अधिकांश क्षेत्रों में 1 से 3 मीटर तक होती है।
