Reference excerpt

Sierra de los Agustinos is a mountain range in Guanajuato state of central Mexico. The range is a protected natural area, and provides water, firewood, recreation for the surrounding region.

Geography The Sierra de los Agustinos are volcanic mountains which rise from the Bajío, a high plain. The Sierra is in the basin of the Lerma River, which runs south and west of the range. The main mass of the Trans-Mexican Volcanic Belt lies to the south and southeast. The volcanic rocks which make up the Sierra are porous and highly fractured, and the Agustinos Aquifer is important source of groundwater in the adjacent lowlands. The range has deposits of non-metallic minerals including as opal, perlite, kaolin, and silica sand.

Flora and fauna The natural vegetation includes tropical deciduous forest at lower elevation, and oak forest at higher elevation. Characteristic trees include palo dulce (Eysenhardtia polystachya) tepeguaje (Lysiloma sp), oak (Quercus spp.), and pinqüica (Arctostaphylos pungens). 531 species of plants have been recorded within the protected natural area. The Sierra is an important habitat for wildlife. 29 mammal species, 145 bird species, 16 reptile species, and three species of amphibians have been recorded in the Sierra. Native mammals include the bobcat (Lynx rufus), ringtail (Bassariscus astutus), white-nosed coati (Nasua narica), raccoon (Procyon lotor), Mexican long-nosed bat (Leptonycteris nivalis), and Saussure's shrew (Sorex saussurei). Native birds include Swainson's hawk (Buteo swainsoni), Mexican falcon (Falco mexicanus), brown-backed solitaire (Myadestes occidentalis). Reptiles include the boa constrictor (Boa constrictor) and black-tailed rattlesnake (Crotalus molossus). The Sierra is part of the annual migration route of the monarch butterfly (Danaus plexippus) between eastern North America and the butterflies' wintering grounds in the mountains of Michoacán and Mexico states to the south.

Conservation The Sierra de los Agustinos was designated a sustainable use area in 2002. It has an area of 191.65 km2.

Worked examples

Example 1 — a first encounter with Sierra de los Agustinos

Start with the simplest possible case. Write down what Sierra de los Agustinos 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 Sierra de los Agustinos 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 Sierra de los Agustinos 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 Sierra de los Agustinos

In research: Sierra de los Agustinos 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 Sierra de los Agustinos 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: Sierra de los Agustinos is common in secondary-school and first-year university syllabi. It links to neighbouring topics Landforms of Guanajuato, Protected areas of Guanajuato, Trans-Mexican Volcanic Belt, so understanding it makes those chapters shorter.
In everyday life: Look for Sierra de los Agustinos 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.
