Question

A dam has broader walls at the bottom than at the top? Explain.

Answer 1

Answer:

1) The deeper the water, the higher the pressure. Hence, the walls of a dam are broad at the bottom so that the walls must not burst.

2) More the area, lesser the pressure. So, to reduce the pressure on the ground, the walls are made thicker at the bottom................

Answer 2

The dam. You can see from the diagram that the dam is much thicker at the bottom than it is at the top. This is because the pressure of the water is much greater deeper down and the dam needs to be thick at the bottom so that it is strong enough to withstand this larger pressure. ... The pressure would be much greater.
