Question

How human activities adversely affect the hydrological cycle. Please Explain!

Answer 1

Hydrological cycles affected by following human activities.

1)Too much exploitation of groundwater lowering the groundwater level below wilting point so that plant root can not extract ground water resulted in failure of Evapotranspiration .it affects hydrological cycle.The cycle of evaporation from stromata of leaves affected by this activities .

2)Due to urbanization in rapid manner, concrete structure are present vast over the soil.It prevents infiltration of groundwater that affects water table and indirectly affects the hydrological cycles.

3)Due to mining activity natural groundwater flow deflected,that affect indirectly hydrological cycle

4)Human induced deforestation at certain area raises temperature which causes more evaporation at particular area.So that some area,gets more rainfall other area becomes drought.

5)Much more agriculture field, enhances the surface run off that affects the hydrological cycles.
