Basic Geography of Rivers
Rivers begin in mountains or hills, where rain water or snowmelt collects and forms tiny streams called gullies. Gullies either grow larger when they collect more water and become streams themselves or meet streams and add to the water already in the stream. When one stream meets another and they merge together, the smaller stream is known as a tributary. The two streams meet at a confluence. It takes many tributary streams to form a river. A river grows larger as it collects water from more tributaries.
Streams usually form rivers in the higher elevations of mountains and hills.
The areas of depression between hills or mountains are known as valleys. A river in the mountains or hills will usually have a deep and steep V-shaped valley as the fast moving water cuts away at the rock as it flows downhill. The fast moving river picks up pieces of rock and carries them downstream, breaking them into smaller and smaller pieces of sediment. By carving and moving rocks, running water changes the earth's surface even more than catastrophic events such as earthquakes or volcanoes.
Leaving the high elevations of the mountains and hills and entering the flat plains, the river slows down. Once the river slows down, the pieces of sediment have a chance to fall to the river bottom and be "deposited". These rocks and pebbles are worn smooth and get smaller as the water continues flowing.
Most of the sediment deposition occurs in the plains. The wide and flat valley of the plains takes thousands of years to create. Here, the river flows slowly, making S-shaped curves which are known as meanders. When the river floods, the river will spread out over many miles on either side of its banks. During floods, the valley is smoothed and tiny pieces of sediment are deposited, sculpting the valley and making it even smoother and more flat. An example of a very flat and smooth river valley is the Mississippi River valley in the United States.
Eventually, a river flows into another large body of water, such as an ocean, bay, or lake. The transition between river and ocean, bay or lake is known as a delta. Most rivers have a delta, an area where the river divides into many channels and river water mixes with sea or lake water as the river water reaches the end of its journey. A famous example of a delta is where the Nile River meets the Mediterranean Sea in Egypt, called the Nile Delta.
From the mountains to the delta, a river does not just flow — it changes the surface of the earth. It cuts rocks, moves boulders, and deposits sediments, constantly attempting to carve away all of the mountains in its path. The goal of the river is to create a wide, flat valley where it can flow smoothly towards the ocean.

Moat at time water from a mountain originates from either a spring or a crater lake on top of the mountain, this water leaves the spring or crater lake and flows down the hill through the gravitational force, this is what determines and causes the meanders a river forms down a mountain, at first water forms tributaries then afterwards the tributaries meet to form a river and finally water reaches the foot of the mountain.
The most part of drinkable water comes from the river.
The journey of river water from moutain regions to plain land territory is often covers a long distance ;
River is mainly generated by the meltdown of higher mountain region's glaciers and it flow in a high current towards the lower altitude regions.Due to high current it breaks the river bank's soils, rocks and carries the substances with it.
When the flow reaches a comparatively lower slope's region the high current is slowed down and the carried substances forms fertile river banks.
After that the flow reaches the plain territory where the speed of the flow is much less due to lack of slope.All the carried substances forms deltas here and after that the flow meets the ocean or any other bigger river or lake etc.
Thus the water flow takes place from mountain regions to the land territory.
The water suddenly emerges and flows through the mountains and valleys, creating a lot of noise. It streams through mother nature, sparkling among ferns and petals. It rushes in high speed through hills, ridges, towns and villages. At last, it joins the brimming river . It flows on forever unlike men who come and go.
*Colours like silver and golden are used while describing the surroundings amidst which flows the water.
The flow is very enthusiastic and jovial spreading positive vibes about the brook. Thus, on this journey of the water it meets many things and visits many places, fulfilling its life just like a human being.
Water flowing down the river is the most interesting aspect to be seen and described
It starts as a small spring which oozes out water like a blood in a cut of animal vein.
It the spreads in form of water fall which finally creates a beautiful scenery which is viewed as a waterfall .
Water rapidly find its way down to the ground and makes it possible to meander on the ground as it forms tides and waves of beautiful view.
why can't you answer it by yourself
now the water gets distributed in different different tributaries and this tributaries travel across the jungles and plains , villages towns and go ahead !!!

is according to the ncert democratic politics textbook
communalism can take various forms in politics :
(i) the most common expression of communalism is in everyday
beliefs. these routinely involve religious prejudices, stereotype of religious
communities and belief in the superiority of one's religion over other
religions. is so common that we often fail to notice it, even when we
believe in it.
(ii) a communal mind often leads to a quest for political
dominance of one's own religious community. for those belonging to majority
community, takes the form of majoritarian dominance. for those belonging
to the minority community, it can take the form of a desire to form a separate
(iii) political mobilisation on religious lines is another
frequent form of communalism. involves the use of sacred symbols,
religious leaders, emotional appeal and plain fear in order to bring the
followers of one religion together in the political arena.
(iv) sometimes communalism takes its most ugly form of
communal violence, riots and massacre.
