Answer:
The correct answer is C. Dams help make irrigation possible so that farming can occur in dry regions .
Step-by-step explanation:
Dams are barriers made of stone, concrete or loose materials, which are usually built in a gorge on a river or stream. They have the purpose of damming the water in the fluvial channel to raise its level in order to derive it, through irrigation pipelines, for its use in supply or irrigation, in the elimination of floods (to avoid flooding downstream of the dam) or to the production of mechanical energy by transforming the potential energy of storage into kinetic energy and this again in mechanics and thus a moving element is driven by the force of water. Mechanical energy can be used directly, as in the old mills, or indirectly to produce electricity, as is done in hydroelectric power plants.
