The , , and mountain ranges are part of the alpine system that dominate in the south.

The Carpathian, Balkan, and Dinark Alps mountain ranges are part of the Alpine system that dominate in the south.

Explanation:

-The Carpathians are a chain of mountains across Central and Eastern Europe. It is the largest chain in continental Europe, offering habitat to Europe's highest populations of brown bears, wolves, chamois and lynx, as well as a third of Europe's plant species. The mountains largely cover the Czech Republic, Slovakia, Poland, Ukraine and Romania. Foothills can be found in Austria, Hungary and Serbia. The longest part is in Romania and the highest part is formed by the High Tatras (up to 2655 m) in Slovakia.

-The Balkan Mountains is a mountain range in the northeastern part of the Balkan Peninsula.  The mountain range forms an extension of the southern Carpathians and has given names to the entire Balkan region in southeastern Europe.   Most of Europe's largest mammals are found here, including brown bears, wolves, wild boars, leopard and deer.

-The Dinark Alps is a mountain range in Southern Europe in the countries of Slovenia, Croatia, Bosnia and Herzegovina, Serbia, Montenegro, Kosovo and Albania. The Dinaric Alps are the most hilly and extensive mountain range in Europe as far as the Caucasus, Alps and Scandinavian mountains are concerned. They are largely formed of sedimentary rocks such as dolomite, limestone, sand and conglomerate formed by oceans and lakes that once covered the area.
