Answer
Diagram showing the the hydrological cycle is given below:
Most of the world's water is being recycled by this continuous process called the hydrological cycle or the water cycle.
- The Sun heats up the water bodies. The water evaporates as water vapour, which being light in weight, rises in the air.
- On reaching the higher, colder levels of the atmosphere, it cools and condenses into tiny water droplets that join to form clouds.
- When the clouds become too heavy and cannot remain suspended in the air, it comes down as precipitation such as rain or snow. Rain is the biggest source of fresh water on the Earth.
- Some of the rainwater seeps underground, some fills up depressions to form lakes, while others just flow into rivers and streams, which carry water to the oceans.
- The cycle is then repeated.

Rising from the Gangotri Glacier in the Himalayas, river Ganga is the lifeline of the northern part of India. Its plains provide food to millions of Indians. The rich fertile plains grow diverse crops and support high density of population. Being a glacier-fed river, it carries water throughout the year and hence provides irrigation, navigation and also helps in the generation of hydroelectric power. On the banks of this sacred river, many pilgrimage cities such as Haridwar, Rishikesh, Allahabad (now Prayagraj) and Varanasi have grown. The combined drainage system of the Indus, Ganga and Brahmaputra forms the vast Northern Plains of the Indian subcontinent that is one of the most populous regions of the world.
