Why the base of the dam is made wider?
The pressure of the water against the top of the dam wall, is much less than the pressure exerted against the bottom of the dam wall. The width of a dam wall increases to compensate for the increased water pressures at the lower level.
Why A dam has broader world at the bottom than at the top?
Due to the that the pressure exerted by a liquid increase with its depth. Thus as depth increase, more and more pressure is exert by water on the wall of dam. A thick wall is required to withstand a great pressure, therefore, the wall of the dam is made with thickness increasing towards the base
How is the fact that the pressure increases with depth taking into account while constucting a wall of dam?
The base of the dam is substantially thicker than the top. The extra thickness adds strength.
What do you call a wall that holds back water?
A wall that holds back water is a dike, levee or dam
Why do you find a reservoir near a dam?
The dam is the wall or structure that holds back fresh water. The reservoir is the whole structure, which includes the dam wall and stored water.
Why are the walls of dam thickened near the base?
why are the walls of a dam thickened near the base
What is a wall barrier that is natural?
A Dam
Why are dams made thinner at the bottom?
This is because the pressure in a liquid increases with depth. This means that the pressure at the bottom of the dam is more. Hence it is more liable to break out from the dam as more pressure is exerted on the walls. So, the walls are thicker at the bottom.
What is an dam?
A dam is way to control floods by putting a large wall across a river
What is a barrier that redicts water called?
It is known as a dam or dam wall. Another structure would be a dike or a levee.
What is a wall built to keep out water?
a dam
What did the fish say when he swam into the wall?
Dam!
