The Armenian Highlands is part of the Alpide belt, forming part of the Asian range that stretches from the Pontic Mountains to the Malay Peninsula. Its total area is about 400,000 km2. Historically, the Armenian Highlands have been the scene of great volcanic activity. Geologically recent volcanism on the area has resulted in large volcanic formations and a series of massifs and tectonic movement has formed the three largest lakes in the Highlands; Lake Sevan, Lake Van and Lake Urmia. The Armenian Highlands are rich in water resources.
