Iztaccihuatl

Iztaccihuatl is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Iztaccihuatl rather than just read about it. In short: Iztaccíhuatl or Ixtaccíhuatl (both forms also spelled without the accent) (Nahuatl pronunciation: [istakˈsiwat͡ɬ] or, as spelled with the x, [iʃtakˈsiwat͡ɬ]) is a 5,230 m (17,160 ft) dormant volcanic mountain in Mexico located on the border between the State of Mexico and Puebla within Izta-Popo Zoquiapan National Park. It is the nation's third highest, after Pico de Orizaba at 5,636 m (18,491 ft), and Popocatépetl…

Key takeaways

  • Iztaccihuatl belongs to earth science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Iztaccihuatl to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Iztaccihuatl from memory before moving on to harder problems.

Reference excerpt

Iztaccíhuatl or Ixtaccíhuatl (both forms also spelled without the accent) (Nahuatl pronunciation: [istakˈsiwat͡ɬ] or, as spelled with the x, [iʃtakˈsiwat͡ɬ]) is a 5,230 m (17,160 ft) dormant volcanic mountain in Mexico located on the border between the State of Mexico and Puebla within Izta-Popo Zoquiapan National Park. It is the nation's third highest, after Pico de Orizaba at 5,636 m (18,491 ft), and Popocatépetl at 5,426 m (17,802 ft). The name "Iztaccíhuatl" is Nahuatl for "White (like salt) woman", reflecting the four individual snow-capped peaks which depict the head, chest, knees and feet of a sleeping female when seen from east or west. Iztaccíhuatl is to the north of its twin Popocatépetl, to which it is connected by the high altitude Paso de Cortés. Depending on atmospheric conditions Iztaccíhuatl is visible much of the year from Mexico City some 70 km (43 mi) to the northwest. The first recorded ascent was made in 1889, though archaeological evidence suggests the Mexica and previous cultures climbed it previously. It is the lowest peak containing permanent snow and glaciers in Mexico.

Geology The summit ridge of the massive 450 km3 (110 cu mi) volcano is a series of overlapping cones constructed along a NNW-SSE line to the south of the Pleistocene Llano Grande caldera. There have been andesitic and dacitic Pleistocene and Holocene eruptions from vents at or near the summit. Areas near the El Pecho summit vent are covered in flows and tuff beds post-dating glaciation, approximately 11,000 years ago. The most recent vents are at El Pecho and a depression at 5,100 m (16,700 ft) along the summit ridge midway between El Pecho and Los Pies.

Legend of Popocatépetl and Iztaccíhuatl

In Tlaxcaltecan mythology, Iztaccíhuatl was a princess who fell in love with one of her father's warriors, Popocatépetl. The emperor sent Popocatépetl to war in Oaxaca, promising him Iztaccíhuatl as his wife when he returned (which Iztaccíhuatl's father presumed he would not). Iztaccíhuatl was falsely told that Popocatépetl had died in battle, and believing the news, she died of grief. When Popocatépetl returned to find his love dead, he took her body to a spot outside Tenochtitlan and knelt by her grave. The gods covered them with snow and changed them into mountains. Iztaccíhuatl's mountain is called "White Woman" (from Nahuatl iztāc "white" and cihuātl "woman") because it resembles a woman lying on her back, and is often covered with snow — the peak is sometimes nicknamed La Mujer Dormida, "The Sleeping Woman". Popocatépetl became an active volcano, raining fire on Earth in blind rage at the loss of his beloved.

Elevation Iztaccihuatl is usually listed at 5,286 m (17,343 ft), but SRTM data and the Mexican national mapping survey assert that a range of 5,220 to 5,230 m (17,130 to 17,160 ft) is more accurate. The Global Volcanism Program cites 5,230 m (17,160 ft).

Worked examples

Example 1 — a first encounter with Iztaccihuatl

Start with the simplest possible case. Write down what Iztaccihuatl claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Iztaccihuatl before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Iztaccihuatl ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Iztaccihuatl

In research
Iztaccihuatl appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Iztaccihuatl in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Iztaccihuatl is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dormant volcanoes, Five-thousanders of North America, Geography of Mesoamerica, so understanding it makes those chapters shorter.
In everyday life
Look for Iztaccihuatl outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
