    Geological map - shows a geological structure of the area surface (i.e. the most risk parts of rock medium) and its structure-tectonic proportions.
    The Czech Republic lies on a boundary surface of  two mountain systems, that are different in the age, structure and mineral composition and consequently in their geologic and geomorphologic evolution. The basic geological units of the Czech Republic are The Czech Massif and the Western Carpathian near its eastern boundary.

    The area of the Czech Republic pertains  to two geomorphologic units - the Hercynian and the Alps-Himalayan system. The western and central parts of the CR form the Hercynian system province - The Czech Highlands. Surface of the Czech Highlands is mostly hilly without typical lowlands. Mountain ranges are usually gently sloped and often interfered with valley rivers. The province of the Alps-Himalayan system - the Western Carpathian - breaches into eastern part of the CR. Dividing line between these two mountain systems is occupied by the range of the Moravian vales.
