General characteristics of the relief of Spain?

Spain is often referred to as the most mountainous country in Europe. About 90% of its territory is occupied by mountains and plateaus. Almost half of Spain’s surface is the Meseta Plateau (the largest in Europe). Its eastern part is leveled and covered with a thick ball of sedimentary rocks. But the western part of Meseta is strongly dissected by faults and river valleys. Plains and lowlands occupy only 10% of the total area of ​​Spain. All of them are composed of alluvial materials, and therefore their soils are extremely fertile. The largest lowland is located in the southwest of the country (Andalusian).
