The correct options are
A Increase in population
B Increase in industries
C Agricultural activities
∙ Increasing population creates demand for construction of houses, shops, offices, roads and pavements. This decreases open areas like parks and playgrounds which reduces seepage of rain water into the soil.
∙ Water used by most of the industries is drawn from the ground and an increase in the number of industries can cause depletion of water table.
∙ Population pressure on agriculture increases use of groundwater. This results in depletion of water table.
∙ Soil erosion is when dirt or soil wears or washes away, exposing the ground underneath. This doesnt afftect the water table.
