Question

45. How is water table formed?​

Answer 1

Answer:

They occur when liquid groundwater saturates pores in the soil and cools rapidly to solid ice. Water is at its densest at 4 °C (39.2 °F), and it expands when it freezes. The freezing of water and its subsequent expansion begin at the surface and continue downward into the soil.

Explanation:

Water table, also called groundwater table, upper level of an underground surface in which the soil or rocks are permanently saturated with water. The water table separates the groundwater zone that lies below it from the capillary fringe, or zone of aeration, that lies above it. The water table fluctuates both with the seasons and from year to year because it is affected by climatic variations and by the amount of precipitation used by vegetation. It also is affected by withdrawing excessive amounts of water from wells or by recharging them artificially. See also aquifer.
