Why are dams bulit broad at the base and narrow at the top?

Expert Answer:

Pressure  at a point is directly proportional to height ( P = h d g)  . So, the pressure or force acting per unit area at the bottom of a dam is much more compared to that at the top; hence dams are built broader at the bottom.
