Question

Why are dams made broader at the bottom than at the top brainly?

Answer 1

because liquid apply more pressure on basement

Answer 2

Pressure exerted by a liquid is dependent on the depth that it increases with greater pressure . That is to say, as the depth increases, pressure applied by water on the walls of the dam also increases. In order to withstand the great pressure, the walls are build thicker. Hence a dam has broader walls at the bottom then at the top.
