The modern convention of the Europe-Asia boundary (from south to north) follows the Aegean Sea<span>, the Dardanelles-Sea of Marmora-Bosporus, the </span>Black Sea<span>, along the watershed of the Greater Caucasus, the northwestern portion of the </span>Caspian Sea<span> and along the </span>Ural River<span> and </span><span>Ural Mountains
