Question

The wall of a dam is made thicker at the bottom because ___.

Options:

A . it is economically feasible

B . it looks beautiful

C . the government has laid down specific regulations to make the base of dams broader

D . it supports increased water pressure at the depth

Answer: Option D
:
D
The pressure in the liquid increases with depth. Thus, as depth increases, more and more pressure is exerted by water on the wall of a dam. A thicker wall is required to withstand a greater pressure, therefore, the wall of the dam is made with the thickness increasing towards base.
