Answer» Why is the WALL of a DAM broad at its bottom?Explanation:The reason is that the pressure exerted by a liquid INCREASES with its depth. Thus, as the depth increases, more and more pressure is exerted by water on the wall of the dam. A thicker wall is required to WITHSTAND GREATER pressure, therefore, the thickness of the dam increases towards the bottom. |
