Geography of European Plains

European Plain, one of the greatest uninterrupted expanses of plain on the Earths surface. It sweeps from the Pyrenees Mountains on the French-Spanish border across northern Europe to the Ural Mountains in Russia. In western Europe the plain is comparatively narrow, rarely exceeding 200 miles (320 kilometers) in width, but as it stretches eastward it broadens steadily until it reaches its greatest width in western Russia, where it extends more than 2,000 miles.
