This document discusses the importance of rivers and provides details on some of the major rivers in the world. It defines key river geography terms like tributaries, distributaries, deltas, and estuaries. It also notes that while rivers provide opportunities, they also pose threats, and that human activities have threatened rivers. Sustainable management of rivers is important as over two-thirds of the world's population will live in water-stressed areas by 2025 due to depletion exceeding natural recharge of rivers.

2. What rivers crisscross the Indiana subcontinent?
• It is characterized by a north-south divide between the
Indo-Gangetic Plain in the north, which includes

the largest by water flow, running through
South America.

4. What are the most important rivers on the planet ?

waterfalls and wildlife.
• The Volga River, the longest river in Europe and the largest in

5. What do the terms, 'source', 'mouth', 'tributary',
'distributary', 'delta' and 'estuary' mean?
• Tributaries are small streams of water that
originates from the glacier and join together
to form a river.
Distributaries are formed when the river
breaks down into small streamlets or
channels.

6. What threats and opportunities do rivers bring
to the people who live on its banks?

7. What threats have humans brought to rivers ?

8. Are all rivers suitable for sustaining a society?
• Water is a finite and irreplaceable resource that is
fundamental to human well-being. It is only renewable if
well managed. Today, more than 1.7 billion people live in
river basins where depletion through use exceeds natural
recharge, a trend that will see two-thirds of the world’s
population living in water-stressed countries by 2025.
