Water of Class 7

Water is present underground as groundwater. The upper layer of the groundwater is called  the water table. The water table may be at a depth of one metre or at a depth of several metres below the ground.

The water from rain, rivers, lakes and ponds seeps through the soil and fills the space below the ground. The process of seeping of water through the soil is called infiltration.

At some places groundwater is stored between layers of hard rock. This is called aquifer. Water from aquifiers is pumped and taken out through hand pumps and tube wells.
