Before reliable measurements were available, Teide was considered by Europeans to be the highest mountain on Earth for a long time. With a height of {{cvt|3715|m|ft}}, it is the highest point in Spain and the Atlantic Ocean.<ref name=wovo>{{cite web|url=http://www.wovo.org/1803.html|website=World Organization of Volcano Observatories|title=Canary Island Volcano Monitoring Program|language=en|date=9 November 2019|archive-url=https://web.archive.org/web/20170223134243/http://www.wovo.org/1803.html|archive-date=23 February 2017}}.</ref> If it is measured from the ocean floor, it surpasses {{cvt|7000|m|ft}}, making it the third highest volcanic structure in the world after [[Mauna Loa]] and [[Mauna Kea]], both on the island of [[Hawaii]].<ref name=carratroll>{{Cite book|url=https://www.worldcat.org/oclc/835630472|title=Teide volcano : geology and eruptions of a highly differentiated oceanic stratovolcano|date=2013|publisher=Springer|editor1=J.

The formation of the mountain is marked by its long and complex volcanic history. It rests on the [[Las Cañadas]] caldera, an asymmetric depression {{cvt|15|km|mi}} in diameter in the form of a horseshoe which opens to the north. The floor of the caldera varies from {{cvt|2000|to|2200|m|ft}} in altitude, although its sides in the south rise to {{cvt|2717|m|ft}}, the level of [[Mount Guajara]]. To the north, the slopes of Teide continue directly to the ocean, with a break in the slope at around {{cvt|2000|m|ft}}. The volcano of Teide itself can be described as a [[volcanic cone]] {{cvt|8|km|mi}} in diameter at its base, with quite steep slopes, approximately 20 to 40° for a total volume of {{cvt|150|to|200|km3}}.<ref name="Girault">{{cite book|language=fr|first1=François|last1=Girault|first2=Philippe|last2=Bouysse|first3=Jean-Philippe|last3=Rançon|title=Volcans vus de l'espace|location=Paris|publisher=[[Nathan (publisher)|Nathan]]|year=1998|pages=21–23|isbn=2-09-260829-0}}.</ref> The summit is marked by a small volcanic cone, about {{cvt|150|m|ft}} high, named {{lang|es|El Pitón}},<ref name="Arnay_de_la_ Rosa_et_al_2006">{{cite web | url=https://whc.unesco.org/uploads/nominations/1258.pdf | title=Proposal to inscribe Teide National Park on the World Heritage List | publisher=[[Ministry of Environment (Spain)|Ministerio de Medio Ambiente]] / Gobierno de Canarias | date=18 January 2006 | accessdate=26 August 2024 | author=Arnay de la Rosa, M. |display-authors=etal | page=216}}</ref> which has a summit crater {{cvt|100|m|ft}} in diameter and {{cvt|30|m|ft}} deep. A secondary cone, named Pico Viejo emerges on the western slopes of the main peak; its crater is much larger, with a diameter of {{cvt|800|m|ft}} and a depth of {{cvt|140|m|ft}}. It rises to {{cvt|3414|m|ft}},<ref name="OAPN">{{cite book|language=es|author1=OAPN|title=Guía de visita Parque Nacional del Teide|year=2015|publisher=Organismo Autónomo de Parques Nacionales |isbn=978-80-8414-883-2|url=https://www.miteco.gob.es/va/red-parques-nacionales/nuestros-parques/teide/guia-teide_tcm39-68119.pdf|access-date=March 31, 2024|archive-date=August 11, 2022|archive-url=https://web.archive.org/web/20220811090739/https://www.miteco.gob.es/va/red-parques-nacionales/nuestros-parques/teide/guia-teide_tcm39-68119.pdf|url-status=live}}</ref> but with a low [[prominence]], not more than {{cvt|100|m|ft}} higher than the slopes of the main volcano. On the outside of these two main peaks, the relief Teide also has some smaller formations, of which the most notable are {{lang|es|Roques Blancos}}, {{lang|es|Pico Cabras}}, and {{lang|es|Montaña Blanca}}, situated next to the base of Teide.<ref name=carratroll />

The slopes of Teide are covered in radial ravines. However, the majority of the ravines have been covered by recent lava flows, the {{lang|es|Lavas Negras}}, in particular the northern part. The main ravines, with prominence around {{cvt|100|m|ft}}, are located on the south slope: from east to west, the {{lang|es|Corredor Mario}}, {{lang|es|Corredor La Corbata}} and {{lang|es|Corredor La Bola}}.<ref name=carratroll />
