===Geology===
{{main|Geology of the Czech Republic}}

Most of the area of the Czech Republic belongs to the geographically stable [[Bohemian Massif]]. Only an area of the [[Western Carpathians]] in the east of the country is younger, lifted during the [[Tertiary]]. Igneous rocks make up the base of the Bohemian Massif. Sedimentary rocks are mostly found in the north-eastern part of [[Bohemia]] with significant areas of sandstone. Among the metamorphic rocks, the most commonly found is [[Gneiss]].

===Mountains===
{{main|List of highest mountains of the Czech Republic}}
The most notable mountain ranges in the Czech Republic are all found along the borders of the country. In [[Bohemia]] it is the [[Bohemian Forest]] and [[Ore Mountains]], both bordering Germany. Then the long region of [[Sudetes]] with several mountains ranges, including [[Giant Mountains]] with [[Sněžka]] – the highest peak of the Czech Republic. The last major mountain range is the [[Moravian-Silesian Beskids]] in the east.

===Rivers===
[[File:Povodí Labe Vltavy Moravy.PNG|thumb|Drainage areas of the Elbe and the Morava rivers]]
{{main|Rivers of the Czech Republic}}

There are four major rivers in the Czech Republic. The [[Elbe]] (locally "Labe") flows from the [[Giant Mountains]] in the north east of Bohemia to the west and then through northern Germany all the way to the [[North Sea]]. The [[Morava (river)|Morava River]] drains most of Moravia and flows to the south into the [[Danube]] and ultimately to the [[Black Sea]]. The [[Oder]] starts in the [[Moravian Silesia]] and flows north through Poland into the [[Baltic Sea]]. The fourth major river is the [[Vltava]], which is the longest river of the Czech Republic and drains the southern part of Bohemia before flowing into the Elbe at [[Mělník]].

===Bodies of water===
{{main|List of ponds of the Czech Republic}}
Natural occurring bodies of water are rather scarce; most of the significant bodies of water are man-made ponds and reservoirs. The largest pond is the [[Rožmberk Pond]], which is one of the system of fish ponds built in the 16th century around [[Třeboň]]. The largest reservoir by area covered is the [[Lipno Reservoir]] (4,870 ha), built in the 1950s and the largest reservoir by volume is [[Orlík Reservoir]] (716 million m<sup>3</sup>), built around the same time. The largest and deepest natural lake is [[Černé jezero]] (18.4 ha).
