Pressure in liquids increases with depth, necessitating structural changes like a thicker dam base. Overinflated balloons can burst due to pressure buildup.
Pressure of a liquid varies as per its depth due to the weight of the liquid above, exerting greater pressure at greater depths. The thicker base of a dam is necessary to withstand the increasing pressure as depth increases in the liquid it holds, following the principle that pressure increases with depth. A strongly blown balloon can get blasted due to the pressure inside exceeding the ability of the balloon material to contain it.
