Witness Hill

Last updated

A witness hill is a type of landform created from the erosion of the earth. It is a testimony of the evolution and retreat of a platform or cuesta relief, that is, it is a rest of the platform in a relief where there are layers of hard and soft rocks arranged horizontally in which erosion has sculpted landscapes that are also horizontal. As the erosion produced by the rivers increases in the soft layers, hills are formed, and if the plateau is attacked by erosion from all sides, the witness hills with flat summits appear. They are therefore, the "witnesses" of the platform that existed in that place millions of years ago. [1]

Some examples of this type of geological formation are: Pilot Mountain, North Carolina, Dori Plateau, Burkina Faso, La Teta Hill, La Guajira Peninsula and the Hills of Guayana, Venezuela. These hills are quite common in the sedimentary basins of the Meseta Central of the Iberian Peninsula, [2] in the Ebro Depression and in the tabular reliefs.

<span class="mw-page-title-main">Topographical relief of Spain</span>

The topographical relief of Spain is characterized by being quite high, with an average altitude of 660 meters above sea level, quite mountainous compared to other European countries and only surpassed by Switzerland, Austria, Greece and the microstates of Andorra and Liechtenstein. In peninsular Spain, the terrain is articulated around a large Meseta Central that occupies most of the center of the Iberian Peninsula. Outside the plateau, there is the depression of the Guadalquivir river, located in the southwest of the peninsula, and the Ebro river depression, located in the northeast.

The history of the territorial organization of Spain, in the modern sense, is a process that began in the 16th century with the dynastic union of the Crown of Aragon and the Crown of Castile, the conquest of the Kingdom of Granada and later the Kingdom of Navarre. However, it is important to clarify the origin of the toponym Spain, as well as the territorial divisions that existed previously in the current Spanish territory.
