Terceira Island

Terceira Island 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 Terceira Island rather than just read about it. In short: Terceira (Portuguese pronunciation: [tɨɾˈsɐjɾɐ]) is a volcanic island in the Azores archipelago of Portugal, 1,181 km (734 mi) due west of Lisbon. It is one of the larger islands of the archipelago, with a population of 53,311 inhabitants in an area of approximately 396.75 km2 (153.19 sq mi).

Key takeaways

  • Terceira Island 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 Terceira Island to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Terceira Island from memory before moving on to harder problems.

Reference excerpt

Terceira (Portuguese pronunciation: [tɨɾˈsɐjɾɐ]) is a volcanic island in the Azores archipelago of Portugal, 1,181 km (734 mi) due west of Lisbon. It is one of the larger islands of the archipelago, with a population of 53,311 inhabitants in an area of approximately 396.75 km2 (153.19 sq mi). Terceira is the location of the Azores' oldest city, Angra do Heroísmo, the historical capital of the archipelago and a UNESCO World Heritage Site; the seat of the judicial system (Supreme Court); and the main insular Portuguese Air Force base, Base Aérea nº 4 at Lajes, with a United States Air Force detachment. Terceira island has two main sea ports, one at Angra do Heroísmo and the other at Praia da Vitória, and a commercial airport integrated with the flight operations at Lajes. Portuguese bullfighting is popular on the island, in two versions: the traditional equestrian bullfight (in the ring) and the popular "tourada à corda" that occurs in the streets.

History

There is some uncertainty in the date and the discoverer of the Azores. Nautical charts before the "official" discovery identified islands in the Atlantic Ocean as early as 1325, when a chart by Angelino Dalorto identified "Bracile" west of Ireland, and later one by Angelino Dulcert which identifies the Canaries, and Madeira, along with mysterious islands denominated as "Capraria" (which some historians suggest were São Miguel and Santa Maria). Legends also persisted of Atlantis, Sete Cidades (Kingdoms of the Seven Cities), the Terras of São Brandão (the Land of Saint Brendan), the Ilhas Afortunadas (the Fortunate Islands), the Ilha da Brasil (the Island of Brasil), Antília, the Ilhas Azuis (Blue Islands), and the Terra dos Bacalhaus (Land of Codfish), and charts appeared between 1351 and 1439 of several groupings of islands with various names. The first association between the modern island of Terceira and these stories, was that of the island of Brasil; it first appears as Insula de Brasil in the Venetian map of Andrea Bianco (1436), attached to one of the larger islands of a group of islands in the Atlantic. In 1439, the first official discovery document appeared, attributing the discovery of the Formigas to Gonçalo Velho Cabral. There is an indication that Terceira may have been discovered by Vicente de Lagos, Velho Cabral's pilot, on 1 January 1445: the first documents after this period started appearing with a third island in the Azorean archipelago, referred to as the Ilha de Jesus Cristo (Island of Jesus Christ), and later, Ilha de Jesus Cristo da Terceira. Gaspar Frutuoso, a chronicler and humanist, would later rationalize about the island's first name, noting that:

it was discovered on the first day of January, traditionally the feast day of the name of Jesus; it was discovered by a captain in the Order of Christ; it was discovered on a Thursday or Friday, on Corpo de Deus (Body of Christ); or because it was part of the dioceses of Angra, through the invocation of San Salvador (although this implies that a dioceses existed prior to its discovery). Regardless, it was only a temporary name, as the colloquial Terceira (meaning "third" in Portuguese, as in "the third island" or "third to be discovered") was used more often to describe the island. The colonization of the island began by decree of Henry the Navigator, dated 21 March 1450, and placed the island in the administrative hands of the Fleming Jácome de Bruges. Its first settler was Fernão d'Ulmo, a Fleming or Frenchman, who later abandoned his plot for unknown reasons. Bruges, although a Flemish nobleman, continued to bring families and settlers from Flanders, and northern Portuguese adventurers (João Coelho, from Guimarães; João da Ponte, from Aveiro; João Bernardes, from Lagos; João Leonarde, from Vieira; and Gonçalo Anes da Fonseca, from Porto), as well as animals and provisions, disembarking in the area of Porto Judeu or Pesqueiro dos Meninos, near Vila de São Sebastião (depending on sources). Frutuoso also affirmed that:

Worked examples

Example 1 — a first encounter with Terceira Island

Start with the simplest possible case. Write down what Terceira Island 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 Terceira Island 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 Terceira Island 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 Terceira Island

In research
Terceira Island 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 Terceira Island 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
Terceira Island is common in secondary-school and first-year university syllabi. It links to neighbouring topics Islands of the Azores, Mountains of Portugal, Stratovolcanoes of Portugal, so understanding it makes those chapters shorter.
In everyday life
Look for Terceira Island 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.

Why does Terceira Island matter?

Because it connects several earth science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Terceira Island?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
