Water-A Precious Resource Notes

• Precipitation in the form of rain or snow provides fresh water to our planet Earth.
• Most of the fresh water returns to the oceans through rivers flowing across the globe.
• A small portion of it is absorbed by the soil and is stored underground.
• A still smaller portion is stored in natural (lakes and ponds) and man-made (tanks and reservoirs) water bodies.
• Various sources of water can be divided into two main categories:

1. Surface water
2. Underground water or subsoil water

Surface Water:

• Water availability in India depends greatly on the seasonal monsoons.
• The monsoons bring heavy rains over most of the country between June and October.
