Editing Rio, Illinois (section)

==Geography==
Rio is situated in the northwest corner of Knox County, {{convert|13|mi}} north of [[Galesburg, Illinois|Galesburg]], the [[county seat]]. Like other rural neighbors, the village has rich soil ideal for farming [[maize|corn]] and [[soybean]]s. A few small, unnamed creeks run through its outskirts, and a few small hills that coast under the streets of the village. A few sizable dropoffs throughout the land almost look like shallow or gradual cliffs as some local agricultural fields are rolling and steep. The land drains to North Henderson Creek, a west-flowing stream leading to [[Henderson Creek (Illinois)|Henderson Creek]] to the [[Mississippi River]] near [[Oquawka, Illinois|Oquawka]].

According to the 2010 census, Rio covers a total area of {{convert|0.27|sqmi|sqkm|2}}, all of which is land.<ref name="census-g001">{{cite web
