In terms of geomorphological division, the Czech Republic is a very diverse territory, located in the territory of four geomorphological provinces within four geomorphological subsystems. The Bohemian Massif within the sub-system of Hercynian Forest forms three quarters of the country. The southeastern and eastern part of the Czech territory belongs to the Western Carpathians within the Carpathian Mountains. The remaining two provinces, within the Pannonian Basin and North European Plain within the European Plain, cover only a small part of the Czech territory in the southeast and the northeast.
