The three big ideas

A river usually begins high in the mountains as melting snow or a spring — this is its source.
It flows downhill, gathering more water and taking a winding path called its course.
At last it reaches the sea or a big lake — its mouth. Along the way, smaller streams called tributaries join and feed it.

Everyday example. Picture a river in your mind. Where does it start, and which way does it flow?

It starts as a thin mountain stream, grows wider as tributaries join on the plains, and ends broad and slow at the sea. Always downhill — never up.

Near the source the land is steep, so the water rushes fast, tumbling over rocks and sometimes making waterfalls.
On flat plains the river slows down and swings in wide curves called meanders.
Fast water carries soil and stones; slow water drops them, building rich, fertile land that is wonderful for farming.

Common mix-up: A river does not flow in a straight line on flat land. It bends and loops a lot — that is completely normal and healthy.

Rivers give water for homes and crops, fertile soil, fish to eat, a route for boats, and electricity from dams. Towns and great cities grew beside them.
But dumping plastic, rubbish and dirty water makes a river sick — fish die and people fall ill.
We protect rivers by not throwing waste into them and by cleaning dirty water before it returns.

Everyday example. Think of a small riverside town. How many things there depend on the river?

Drinking water, fishing boats, washing clothes, watering fields, a temple by the bank — all of them need the river to stay clean.

Rivers in our lives

Farming on river plains

The soil a river leaves behind is rich and soft, perfect for growing crops. That is why so much of our food is grown on river plains.

Cities by the river

Many old Indian cities sit on river banks because the river gave water, food and an easy way to travel.

Cleaning our rivers

Clean-up drives, dustbins along the banks, and treating waste water before it reaches the river all keep rivers healthy for fish and for us.
