Question

Dams have broad Foundation why

Answer 1

Answer:

Explanation: this is done in order reduce the pressure exerted by the sea/lake/river water. As

Pressure = Force/Area. Thus increasing the area will reduce the pressure on the walls of dam which prevents it from serious damage

Answer 2

As we know that , pressure is the force acting per unit area.dams have large water storage.If the bottom of the dams are not made broad , the large hydraulic pressure may cause dams to sink into the earth's basin.So,an increase in base area,decreases the pressure exerted by large water storage.
