Question

Quizplus · Accepted Answer

A dam is a man-made structure designed to obstruct and control the flow of a river or stream. It is intended to impound water and create a reservoir for various purposes such as hydroelectric power, irrigation, or flood control. Therefore, it is a barrier that blocks or restricts the downstream movement of a stream. The other options, such as natural levees, artificial levees, waterfalls, or deltas, do not necessarily obstruct or restrict the downstream movement of a stream, but they can affect the stream's channel or create specific landforms.
