Drainage Himalayan Rivers Video Lecture - Social Studies (SST) Class 9

0:0:0: have you guys seen a river I am sure you
0:0:3: all have the river system of an area
0:0:6: which includes the river and its
0:0:8: tributaries is called
0:0:10: drainage in this video we will dive deep
0:0:13: into drainage and study some important
0:0:16: terms related to
0:0:18: drainage then we will study about
0:0:20: drainage systems in India and the
0:0:23: difference between the two types of
0:0:25: rivers that is Himalayan rivers and
0:0:27: Peninsular rivers and also Al learn some
0:0:30: more about Himalayan Rivers first of all
0:0:34: we will study the important terms the
0:0:37: first term which we have already studied
0:0:40: is drainage the river system of an
0:0:43: area drainage basin the area drained by
0:0:47: a single River and its tributaries is
0:0:50: called drainage
0:0:51: basin like this complete area is drained
0:0:55: by this River so the area will be called
0:0:58: the drainage basin
0:1:0: water divide any elevated area such as a
0:1:4: mountain or an Upland that divides two
0:1:7: drainage
0:1:8: basins gge it is a narrow Valley between
0:1:12: Hills or mountains typically with steep
0:1:15: Rocky walls and a stream running through
0:1:17: it observe this it is called a
0:1:21: gge tributaries these are called
0:1:25: tributaries the small rivers joining a
0:1:28: bigger River are called its
0:1:30: tributaries let's see the drainage
0:1:32: systems in India the Indian Rivers are
0:1:36: divided into two major groups namely the
0:1:39: Himalayan rivers and the peninsula
0:1:42: Rivers based on their
0:1:44: origination now we'll cover the
0:1:47: difference between the two types of
0:1:49: rivers Himalayan Rivers originate from
0:1:53: glaciers Peninsular Rivers originate
0:1:56: from plateaus and Central
0:1:58: Highland they have have large River
0:2:0: Basin they have smaller river basins
0:2:4: Himalayan Rivers depend on melting of
0:2:6: snow and rain for water Peninsular
0:2:9: Rivers depend majorly on
0:2:12: rainfall these rivers are perennial and
0:2:14: flow throughout the year whereas these
0:2:17: are seasonal
0:2:18: Rivers they are engaged in high erosion
0:2:21: activity they have very little erosion
0:2:25: activity their course from the origin to
0:2:28: the sea is long whereas their course is
0:2:31: shorter they have cut through the
0:2:33: mountains making
0:2:34: Gorges they have shallow valleys some
0:2:38: examples include brahmaputra ganga and
0:2:42: indas examples are godavari and
0:2:46: NADA let's see the Himalayan Rivers
0:2:49: closely the major Himalayan rivers are
0:2:52: the indas the ganga and the
0:2:55: brahmaputra these rivers are long and
0:2:58: are joined by many large and important
0:3:2: tributaries first is the Indus River
0:3:4: system the river Indus rises in Tibet
0:3:8: near Lake Manser over flowing West it
0:3:12: enters India in the ladak district of
0:3:14: Jammu and
0:3:15: Kashmir India possesses only onethird of
0:3:18: the river's length after Jammu and
0:3:21: Kashmir it enters into Pakistan which
0:3:24: holds the major part of Indus River
0:3:27: other rivers like Ravi chinab Bas satluj
0:3:32: and jam together enter the indas river
0:3:35: near mitan cour in Pakistan after this
0:3:39: the river eventually reaches the Arabian
0:3:41: Sea in
0:3:42: Karachi next we move to the ganga river
0:3:46: system an interesting fact that you
0:3:48: should remember for exams is that ganga
0:3:51: is not called ganga right from where it
0:3:55: originates instead the headwaters of
0:3:57: Ganga is called bhiti which is fed by
0:4:1: the gangotri
0:4:2: glacier it is only after the river alak
0:4:5: Nanda joins bhagti at De prayag in uttar
0:4:9: Pradesh that the joint river is called
0:4:12: ganga at haridwar the ganga emerges from
0:4:15: the mountains onto the
0:4:17: plains the ganga is joined by many
0:4:20: tributaries a few of them being major
0:4:23: rivers such as the yamuna tagara the
0:4:26: gandak and the
0:4:28: kosi here we can see that the river
0:4:31: yamuna originating from the yamunotri
0:4:34: glacier travels parallel to ganga until
0:4:37: it meets it in alahabad
0:4:39: rivers from Nepal flood Northern Plains
0:4:43: annually carrying eroded soil this
0:4:46: enriches the soil supporting extensive
0:4:49: agriculture with valuable
0:4:51: nutrients ganga and the brahmaputra join
0:4:54: to form Magna in Bangladesh before
0:4:57: entering the Bay of Bengal the total
0:4:59: length of Ganga is
0:5:1: 2,500
0:5:3: kilm also Amala acts as a water divide
0:5:6: between the indas and the
0:5:9: ganga the last of the Himalayan Rivers
0:5:12: we are going to study is the brahmaputra
0:5:14: river
0:5:15: system rises in Tibet east of Manser
0:5:19: over Lake very close to the sources of
0:5:22: the Indus and the satluj most of its
0:5:24: course is outside India on reaching the
0:5:28: namcha Bara it takes a U turn and enters
0:5:31: India in arunachal Pradesh through a
0:5:34: Gorge here it is called the diang and it
0:5:37: is joined by the debang the lohit and
0:5:41: many other tributaries to form the
0:5:43: brahmaputra in Assam here the river
0:5:46: carries a large volume of water and
0:5:48: considerable amount of
0:5:50: silt in this video we have covered the
0:5:53: Himalayan rivers and will cover the
0:5:56: Peninsular rivers in the next video we
0:6:0: hope that you have understood the
0:6:1: Himalayan
0:6:2: Rivers now here's a secret on how you
0:6:6: can study effectively with the edu rev
0:6:8: app you can learn with chapter notes
0:6:12: watch video lectures and solve ncer
0:6:15: based McQ tests of this chapter on edu
0:6:18: rev and that's not all you also get
0:6:21: amazing courses for class 9 and much
0:6:23: more for your class 9
0:6:25: preparation thank
