erosion, has a gently undulating surface, with little difference in height
between the valleys and watersheds. It consists of ancient and eroded materials.
In temperate countries is recognized by the regularity of the surfaces, the
watersheds all have the same elevation, the valleys have cut back these
dating from the Tertiary peneplain. His training for the final cycle
erosion that is completed with the total destruction of the reliefs with the result of a
monotonous relief and little above the base level. In Spain are located in the
west of the northern sub-plateau. The peneplain Extremadura is a great extension that
are between 300 and 500 m. altitude and consists of a Paleozoic base
crossed by the River Guadiana.
—Aquifer: water bag inside the rocks. Water in aquifers can
remain stored for hundreds of years in Spain are a storehouse of great
value given the climate of the peninsula. aquifers when they reach their
maximum storage, ie, its water table, water seeks an output that can be
as a spring or river.
– Habitat: Location of buildings and urban structures in space
relation to different landscape elements, both physical and human. habitat
can be dispersed or concentrated, the latter is the largest grouping of
part of Spanish territory, is characterized by the formation of compact nuclei
population.
