What is groundwater? Name the main source of groundwater.
It is found from following sources:
(i) Meteoric Water:This is the main source of groundwater. This water is received in the form of rain and snow. Water from tanks, lakes, rivers and seas is again received by earth after vaporization. Water is received by melting of snow or rain, hence it is called ‘meteoric’ or ‘shooting star water’.
(ii) Connate Water:Water contained in pores and cavities of sedimentary rocks under seas and lakes is called connate water. It is also called ‘sediment water’. It is the second important source of groundwater.
(iii) Magmatic Water:Hot magma enters rocks due to volcanic action after which its vapour drops are condensed and converted into water. This is called magmatic water.
Apart from it, other sources are those in which groundwater becomes again available on the surface of the earth.
They are mainly springs, wells, and geysers.
Hope this helps :)
