Editing Aragon (section)

=== Relief ===
The orography of the community has as the central axis the [[Ebro valley]] (with heights between 150 and 300 meters approx.) which transits between two foothill areas, the Pyrenean and the Iberian, preambles of two mountain formations, the [[Pyrenees]] to the north and the [[Sistema Ibérico]] mountain range to the south; the Community has the highest peaks of both mountain ranges, the [[Aneto]] and the [[Moncayo Massif|Moncayo]] respectively.

==== Pyrenees ====

The Aragonese [[Pyrenees]] are located in the north of the [[province of Huesca]] and are arranged longitudinally in three large units: High Pyrenees, Internal Depressions and Outer Ranges.

The Aragonese High Pyrenees contains the [[Pyrenees#Highest summits|maximum heights]] of all the Pyrenees mountainous chain. The High Pyrenees is formed in turn by the axial Pyrenees and the Inland Ranges.

In the axial Pyrenees are the oldest materials: [[granite]]s, [[quartzite]]s, [[slate]]s and [[limestone]]s and the highest peaks like: the [[Aneto]] ({{val|3404|u=m|fmt=gaps}}), [[Maladeta]] ({{val|3309|u=m|fmt=gaps}}) and the [[Perdiguero]] ({{val|3221|u=m|fmt=gaps}}). The inner Pre-Pyrenees, composed of more modern rocks (limestones) also has large mountains such as [[Monte Perdido]] ({{val|3355|u=m|fmt=gaps}}), [[Collarada]] ({{val|2886|u=m|fmt=gaps}}) and [[Tendeñera]] ({{val|2853|u=m|fmt=gaps}}).

The main Pyrenean valleys are formed by the rivers that are born there, which are:
* [[Ansó Valley]]: [[Veral (river)|Veral river]]
* [[Valle de Hecho|Hecho Valley]]: [[Aragón Subordán|Aragón Subordán river]]
* [[Canfranc Valley]]: [[Aragón (river)|Aragón river]]
* [[Tena Valley]]: [[Gállego (river)|Gállego river]]
* [[Broto Valley]]: [[Ara river (Province of Huesca)|Ara river]]
* [[Aínsa Valley]]: [[Cinca (Spain)|Cinca river]]
** [[Pineta Valley]]: Cinca river
** [[Gistau Valley]]: [[Cinqueta|Cinqueta river]]
* [[Benasque Valley]]: [[Ésera|Ésera river]]

The intrapirenaic depression is a broad perpendicular corridor. Its best represented section is the [[Canal of Berdún (geography)|Canal de Berdún]], which limits on the south with the reliefs of [[Royal Monastery of San Juan de la Peña|San Juan de la Peña]] ({{val|1552|u=m|fmt=gaps}}) and [[Oroel Rock]] ({{val|1769|u=m|fmt=gaps}}), modeled on conglomerates of the Campodarbe Formation.

The pre-Pyrenean outer ranges are in the Huescan foothills and constitute the southernmost unit of the Pyrenees; formed by predominantly calcareous materials, reach heights between {{val|1500|fmt=gaps}} and {{val|2000|fmt=gaps}} meters. The [[Sierra de Guara]], one of the most important mountain ranges of the Spanish [[Pre-Pyrenees]], stands out; its summit, the [[Guara Peak]], reaches {{val|2077|fmt=gaps}} metres.<ref>{{Cite web|url=http://guara.org/wp-content/uploads/2017/06/folleto_guara_fr_en.pdf|title=Sierra de Guara|date=2018-03-17|website=Sierra de Guara|archive-url=https://web.archive.org/web/20180317115302/http://guara.org/wp-content/uploads/2017/06/folleto_guara_fr_en.pdf|archive-date=2018-03-17|access-date=2018-03-17}}</ref> The [[Mallos de Riglos]], near the town of [[Ayerbe]], stand out for their beauty.

==== Depression of the Ebro ====
The Aragonese central depression includes a wide lowland area, which is also the central part of the [[Ebro Valley|Depression of the Ebro]]. North of the river there is the [[Sierra de Alcubierre]] ranges ({{val|811|u=m}}) one of the typical limestone plateaus of the valley.

The [[Ebro Valley]] is a tectonic pit filled with sedimentary materials, accumulated in the [[Cenozoic|Tertiary age]] in horizontal series. In the center, fine materials such as [[clay]]s, [[plaster]]s and [[limestone]]s were deposited. To the south of the [[Ebro]] there are the limestone plateaus of [[Borja, Province of Zaragoza|Borja]] and of [[Zaragoza]].

==== Sistema Ibérico ====
[[File:Moncayo desde Tarazona.jpg|thumb|[[Moncayo Massif]] seen from [[Tarazona]]. Moncayo, with its height of {{val|2314.3|u=m|fmt=gaps}}, is the maximum summit of the Sistema Ibérico mountainous chain.]]

The Aragonese section of the [[Sistema Ibérico]] straddles the provinces of [[Province of Zaragoza|Zaragoza]] and [[Province of Teruel|Teruel]]. It is a set of hills without a clear structural unit, which can be divided into two zones: Sistema Ibérico del Jalón and Sistema Ibérico turolense. In the first, the [[Moncayo Massif|Moncayo]] stands out with {{val|2314|u=m|fmt=gaps}}, formed by Paleozoic quartzites and [[slate]]s, partly covered by Mesozoic [[limestone]]s. The second is formed by elevated terrain (from {{val|1000|fmt=gaps}} to {{val|2000|u=m|fmt=gaps}} in general), but flattened and massive. To the southwest of the depression the summits of the [[Sierra de Albarracín]] range are reached above {{val|1800|u=m|fmt=gaps}}, southeast the {{val|2000|u=m|fmt=gaps}} are reached in the [[Sierra de Javalambre]] range and finally the [[Sierra de Gúdar]] range ({{val|2024|u=m|fmt=gaps}}) transitions to the [[Maestrazgo]] area in the [[Valencian Community]].
