height of himalayas is greater at east and lesser at west
division of himalayas: divided into 3 parallel ranges and no.of valleys lies b/w this ranges
himachal, lesser himalaya

most rugged(rough, uneven, rocky) mountain range
made of highly compressed and altered rocks
height varries from 4,500m to 3,700m
width: 50km
important ranges
pir panjal
natural barrier: because seperstes river system and directly influence weather system of that regions
most imp range
it also has various tunnels that connet to other regions of that area directly effecting security of our country
it plays a mojor role in tourism as well and trasportation too that connects other regions
dhaula dhar
imp range

PENINSULAR PLATEAU
PENINSULAR MEANS LAND COVERED BY WATER ON THREE SIDES
plateau means elevated land from main land whose top surface is flat
also known as table land
division of north indian planes
punjab plain
western part of northern plane
formed by indus and its tributaries
large part of northern plain lies in pakisthan
DOAB: land b/w two rivers is called doab
THE NOETHERN PLANE:
formed by indus ganga ans bramhaputra and their tributaries
they deposite alluvium(loose soil particles not compact) at foot hills of himalayas
this becomes alluvial soil over a period of time and formed as a fertile plain
riverine island/ river island
when rivers are flowing at mountsin slopes the water flows very fast as there is high velocity
when water enter into land slope is very gengle(less) or no slope at all at this time velocity comparatively decreases and water flows slowly
when this water is flowing slowly deposition happens in the middle of river
fertile soil, along with sediments will be deposited in the middle of river
over a period of time due to availability of fertile soil and water of river some vegetation happen
inth middle of river a piece of land with vegetation is called riverine island
def: island formed by river and surrounder completely by river water
MAJULI is fomous riverine island in the world formed by bramhaputra river
distributaries: spliting of river into various channels due to distribution of slit
various channels are called distributaries
area: 7 lakh sq.km
measurements
length/ long 2,400km
broad: 240 to 320 km
highly populated area
adequate water
fertile soil
climate favourable for agriculture
concept
riverine island
land surroundded by water on all sides
doab
tract of land(large area) located b/w two converging or confluent rivers
