A concrete dam is constructed to hold back water in a large reservoir. The wall of the dam is designed to be much thicker at the bottom than at the top.
Why is the dam designed this way?
The density of the water is significantly greater at the bottom.
The pressure exerted by the water increases with depth.
The speed of the water is greatest at the bottom.
The temperature of the water is higher at the bottom.
