4. Water in the Oceans
Underground water resources include water which has become underground through percolation or seepage and is lying in the porous rocks.
Water resources available on surface are not totally usable. Due to saltness, water available in seas and cans is not usable. Only water found in rivers and lakes and underground water is usable. Underground water is obtained through bore well, artesian well, geysers and springs.
