Answer the following questions in not more than 125 words.<\/h3>\n\n\n\n<p><strong>(i) What are the important characteristic features of north Indian rivers? How are these different from Peninsular rivers?<\/strong><\/p>\n\n\n\n<p><strong>Solutions<\/strong>: North Indian (Himalayan) rivers are perennial, fed by snowmelt and rainfall, ensuring year-round flow. They have long courses, extensive meandering, large basins, and form vast, fertile deltas with heavy sediment load. They erode deeply in upper reaches and deposit alluvium in plains, supporting dense population and agriculture.<\/p>\n\n\n\n<p>Peninsular rivers are mostly seasonal, rain-fed, with low flow in the dry season. They are shorter, flow in relatively straight courses over stable plateaus, form estuaries, have smaller basins, fixed channels and create waterfalls due to hard rock terrain. Unlike Himalayan rivers, they lack snow-fed perennial flow and large deltaic deposits, making them less prone to shifting courses but more dependent on monsoon variability.<\/p>\n\n\n\n<p><strong>(ii) Suppose you are travelling from Haridwar to Siliguri along the foothills of the Himalayas. Name the important rivers you will come across. Describe the characteristics of any one of them.<\/strong><\/p>\n\n\n\n<p><strong>Solutions<\/strong>: Travelling eastward from Haridwar to Siliguri along the Himalayan foothills (through Uttarakhand, Uttar Pradesh, Bihar, and West Bengal), the important rivers crossed are: Ganga (near Haridwar), Ramganga, Ghaghra, Gandak, Kosi, and finally Teesta (near Siliguri).<\/p>\n\n\n\n<p>Characteristics of the Kosi River: Known as the \u2018Sorrow of Bihar\u2019, the Kosi originates in Tibet, flows through Nepal, and joins the Ganga in Bihar. It carries an enormous silt load, frequently shifts its course (up to 120 km in historical times), causes devastating floods, has numerous tributaries (forming a fan-shaped drainage), and is an antecedent river cutting through the Himalayas.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-download-ncert-solutions-class-11-geography-india-physical-environment-chapter-3-drainage-system\">Download NCERT Solutions Class 11 Geography India Physical Environment Chapter 3: Drainage System<\/h2>\n\n\n\n<p>Download the free PDF of these solutions to study key concepts in simple language and prepare effectively for your exams.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-background has-fixed-layout\" style=\"background-color:#fad3dc\"><tbody><tr><td><a href=\"https:\/\/drive.google.com\/file\/d\/1bq0N47mxLD8nZ2w5d0eIQqMImGTUtkU3\/view?usp=sharing\"><strong>Download PDF of NCERT Solutions Class 11 Geography India Physical Environment Chapter 3: Drainage System<\/strong><\/a><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><strong>Download NCERT Solutions of Class 11 India Physical Environment here:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-background has-fixed-layout\" style=\"background-color:#feecbc\"><tbody><tr><td><strong>Chapter 1<\/strong><\/td><td><strong>Chapter 3<\/strong><\/td><td><strong>Chapter 4<\/strong><\/td><td><strong>Chapter 5<\/strong><\/td><td><strong>Chapter 6<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><strong>Related Reads<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-pale-ocean-gradient-background has-background has-fixed-layout\"><tbody><tr><td><a href=\"https:\/\/leverageedu.com\/discover\/school-education\/ncert-solutions-class-11-geography-fundamentals-of-geography-chapter-7-composition-and-structure-of-atmosphere\/\"><strong>NCERT Solutions Class 11 Geography Fundamentals of Geography Chapter 7 Composition and Structure of Atmosphere (Free PDF)<\/strong><\/a><\/td><td><a href=\"https:\/\/leverageedu.com\/discover\/school-education\/ncert-solutions-class-11-geography-fundamentals-of-physical-geography-chapter-11-world-climate-and-climate-change\/\"><strong>NCERT Solutions Class 11 Geography Fundamentals of Physical Geography Chapter 11: World Climate and Climate Change (Free PDF)<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/blog\/chemistry-project-for-class-12\/\"><strong>Chemistry Project Ideas for Class 12 with Free Samples<\/strong><\/a><\/td><td><a href=\"https:\/\/leverageedu.com\/blog\/business-studies-class-12-project\/\"><strong>Business Studies Project Class 12<\/strong><\/a><br><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/blog\/child-development-pedagogy-notes\/\"><strong>Child Development & Pedagogy<\/strong><\/a><br><\/td><td><a href=\"https:\/\/leverageedu.com\/discover\/school-education\/ncert-solutions-class-11-geography-fundamentals-of-physical-geography-chapter-13-movements-of-ocean-water\/\"><strong>NCERT Solutions Class 11 Geography Fundamentals of Physical Geography Chapter 13: Movements of Ocean Water (Free PDF)<\/strong><\/a><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><strong>For more topics, follow LeverageEdu <\/strong><a href=\"https:\/\/leverageedu.com\/discover\/category\/school-education\/ncert-study-material\/\"><strong>NCERT Study Material<\/strong><\/a><strong> today!\u00a0<\/strong><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"Students who are looking to revise the NCERT solutions for Class 11 Geography Chapter 3: Drainage System can&hellip;\n","protected":false},"author":122,"featured_media":874358,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"editor_notices":[],"footnotes":""},"categories":[477,389],"tags":[],"class_list":{"0":"post-874566","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-ncert-study-material","8":"category-school-education"},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.5 (Yoast SEO v27.5) -
