RELIEF FORMS OF THE CONTINENTS. 49 [NS regions. The great low plain lies on the north, and the predominant mountain-system on the south. The coun- try north of this line is sometimes called Low Europe, and that south of it, High Europe. 123. The Predominant Mountain-System of Eu- rope is composed of a highly complex series of mountain-systems extending along the northern shores of the Mediterranean in a curve, from the Straits of Gibraltar to the shores of Asia Minor. The system is highest in the centre, where the Alps form the culminating point of the continent. The average elevation of the Alps ranges from 10,000 to 12,000 feet. Blane, 15,787 feet, is the culminating point of the European continent. Matterhorn and Monte Rosa are but little inferior in height. On the south- west the system is continued to the Atlantic by the Cevennes and adjoining ranges in France, and the Pyrenees and Cantabrian in the northern part of the Spanish peninsula. The Pyrenees are an elevated range, with peaks over 11,000 feet high. On the east the system extends in two curves to the Black Sea by the Carpathian and Transylva- nian Mountains on the north, and the Dinaric Alps and the Balkan Mountains on the south. 124. Divisions of Predominant System.—The predominant mountain-system of Europe may be conveniently regarded as consisting of a central body or axis, the Alps, with six projections or limbs—three on the north, and three on the south. The three divisions on the north include— The Western Division, or the mountains of France, including the mountains lying west of the valleys of the Rhine and the Rhone; The Central Division, or the mountains of Ger- many, situated between the Western Division and the upper valleys of the Oder and the Danube ; The Eastern Division, or the mountains of Austria-Hungary, situated between the Central Division and the Black Sea. These divisions contain a highly complicated system of minor elevations. Their complexity is' due to the fre- quent intersection of the north-eastern and north-western trends. Basin-shaped~ plateaus, like the Bohemian and Transylvanian, are thus formed. : The Western Division includes most of the mountains of France, as the Cevennes, the mountains of Auvergne, and the Vosges Mountains. i The Central Division includes the Jura Mountains in Switzerland, the Swiss and the Bavarian plateaus, the Black Forest Mountains, the Hartz Mountains, and the Bohemian plateau. The Eastern Division includes most of the mountains of Austria, as the Carpathians, the Hungarian Forest, and the Transylvanian Mountains. 125, The three projections on the south are the The highest peak, Mont three mountainous peninsulas of Southern Eu- rope: The Iberian Peninsula, including Spain and Portugal ; The Italian Peninsula ; : The Turco-Grecian Peninsula. The Iberian Peninsula.The principal mountains are the Sierra Estrella, the mountains of Castile, and the Sierra Nevada. The Pyrenees separate the Peninsula from France. The Cantabrian Mountains extend along the northern coast. The Italian Peninsula contains the Apennines, ex- tending mainly in the direction of the north-western trend. The Turco-Grecian Peninsula.—The Dinaric Alps extend along the coast of the Adriatic; the Balkan Moun- tains extend from east to west, through Turkey; and the Pindus from north to south, through Turkey and Greece. 126. The Secondary Mountain-Systems of Eu- rope comprise the system of the Scandinavian peninsula, the Ural Mountains, and the Cauca- sus Mountains. The System of the Scandinavian Peninsula includes the elevations of Norway and Sweden. With the exception of the Kiolen Mountains in the north, the system does not embrace distinct mountain-ridges, but consists mainly of a series Fig. 48, Fiord on Norway Coast, of broad plateaus that descend abruptly on the west in numerous deeply-cut valleys called fiords, through which the sea penetrates nearly to the heart of the plateaus. Fiords are valleys that were deeply eroded by slowly moving masses of
