Geology
The formation of the Iberian Peninsula was completed following what is called 'the most important process of the geological history of southern Europe', in other words, an Alpine-Himalayan tectonic movement, which occurred in the Tertiary era.
Almost the entire morphology of mainland Spain was formed in the Tertiary era. The Pyrenees, the Andalusian, Cantabrian, Iberian and Sierra Morena mountain ranges, as well as the sedimentary basins of the Ebro and the Guadalquivir rivers were formed. The uplifting occured by means of faults in the Galician massif, defining the Central System and the Toledo mountains, and therefore, the unevenness that exists between the two plateaux. The marks left by these tectonic movements have fundamentally remained until present day. It can therefore be said that they gave rise to the geography of the peninsula as it is known today.
Morphology
Spain: a country of great and varied landscape and geographical wealth.
Spain is geographically divided into very distinct territories. It's average altitude is high at 660 metres, in other words, two times the European average. Its highest peaks are the Teide (3,718 metres), on the island of Tenerife; the Mulhacén (3,478 m), in Granada; and the Aneto (3,404 m), in the Pyrenees. The coasts have very diverse outlines, as they belong to different climatic systems and are surrounded by different seas and oceans. The overall structure of the Peninsula could be described as follows. A great central high plateau (the Castilian plateau) cut into two sub-plateaux (north and south) and divided by the Central and Toledo mountain systems. This plateau is surrounded by other mountainous structures on its periphery: the Galician massif, the Cantabrian mountain range, the Iberian System and the Sierra Morena. Three exterior systems define the mountainous structure of the Peninsula; they are the Pyrenean, Andalusian and Catalan mountain ranges. The Canary Islands is the region with the longest coastlines (1,583 km) and its land rises up over volcanic accumulations. The Balearics, on the other hand, have a varied relief composed of the Tramuntana mountain range in Mallorca, the low lands of the island of Menorca -where the land level does not exceed 300 metres, except in El Toro (355 m)- and the smooth relief of Ibiza, where the highest altitudes are Sa Talaiassa (475 m) and the Puig Gros (415 m).
Geographical location
Spain covers an area of 505,955 square kilometres, which places it amongst the fifty largest countries in the world.
The largest part of the territory is located in the Iberian Peninsula, the remainder, approximately 12,500 square kilometres, are islands, -Balearics and the Canary Islands- plus 32 square kilometres that are accounted for by the cities of Ceuta and Melilla, situated on the coast of Africa. The situation of the Iberian Peninsula in the extreme south west of Europe and only 14 kilometres away from the African continent, endows Spain with a great strategic value: projecting into the Mediterranean on one side and acting as an intersection on the path to Africa and America on the other. The fact that a large part of Spain is peninsular also explains the length of its coastline, which runs along the Atlantic Ocean and the Mediterranean sea. As a result of its position, between 36 and 43 degrees North latitude, the climate ranges from the mild oceanic climate in the North, to the continental Mediterranean in the centre and the Mediterranean in the East and South, factors which combine to create a wet Spain in the North and mountainous areas, green Spain with luxuriant forests and a dry Spain in the Mediterranean.
