Why is the great plains of India rich in ground water resources?


The great plains of India rich in ground water because water percolates easily in the alluvial soils and hence, the potentiality of the ground water development is high in the great plains of India. The soft sedimentary rocks easily seep surface water. Contrary to it, seepage of water in the hard rocks of south India is very slow.

What are the major water resources?


Major water resources are:


1. Surface water: It is found in tanks, ponds and rivers.

2. Ground water: A part of surface water which percolates easily in the alluvial soils is ground water.

3. Atmospheric water: It is found in the form of water vapour which falls down on land surface in the form of rainfall and snowfall.

4. Ocean water: Main source of fresh water on land is ocean water. Water from ocean is evaporated and transferred into atmosphere in the form of water vapour and it is converted into water or snow and fall on the ground in the form of rainfall and snow fall.
