Rivers, or river courses, have always been, and are to this day, one of the most important resources for the survival of humanity. It is they who use much of the water they consume, who use to produce our food, which is necessary for our hygiene and which is used to irrigate or soil the agricultural areas.
In addition, rivers are also very important in that they are used in various regions as natural routes of circulation along which, as vessels move carrying goods and people; and also for its use in the production of hydropower, without forgetting the importance they have for the exploitation of fisheries as a food source.

Answer:
Liquid conservation
Explanation:
Jean Piaget proposed, as part of his cognitive development theory, that around ages 7 to 11, children develop the idea of "conservation"
This concept refers to the thinking ability that allows a person to know that a certain quantity of liquid or mass will remain the same despite being changed of container, shape, or apparent size.
In this example, Rochelle has a glass of Kool-Aid, she pours it into a different container (a teacup) and then into a beer stein and then into the original glass. <u>Younger children would think that the teacup has less liquid (since it's smaller) and that a significant amount of liquid is lost while doing all this changes from recipient to recipient. </u>
<u />
<u>However, Rochelle knows that this quantity of Kool-Aid remained the same despite being changed of container</u>, thus, this is an example of liquid conservation.
