Which of these European mountain ranges forms an arc throughout Central and Eastern Europe?

The Carpathian Mountains are a range of mountains forming an arc throughout Central and Eastern Europe. Roughly 1,500 km (932 mi) long, it is the third-longest European mountain range after the Urals with 2,500 km (1,553 mi) and the Scandinavian Mountains with 1,700 km (1,056 mi).

The range stretches from the far eastern Czech Republic (3%) in the northwest through Slovakia (17%), Poland (10%), Hungary (4%) and Ukraine (10%) Serbia (5%) and Romania (50%) in the southeast.

The highest range within the Carpathians is known as the Tatra mountains in Slovakia, where the highest peaks exceed 2,600 m (8,530 ft). The second-highest range is the Southern Carpathians in Romania, where the highest peaks range between 2,500 m (8,202 ft) and 2,550 m (8,366 ft).

The Carpathians provide habitat for the largest European populations of brown bears, wolves, chamois, and lynxes, as well as over one-third of all European plant species. The mountains and their foothills also have many thermal and mineral waters.
