Alps, Europe

The Alps, one of the great mountain range systems of Europe, stretch approximately 1,200 kilometres across eight Alpine countries. The Alps were formed over hundreds of millions of years as the African and Eurasian tectonic plates collided. Mont Blanc spans the French–Italian border, and at 4,810.45 m is the highest mountain in the Alps. The Alpine region area contains many peaks higher than 4,000 m, known as the "four-thousanders".
