Ourique (meteorite)

Ourique (meteorite) is a 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 Ourique (meteorite) rather than just read about it. In short: Ourique is a H4 meteorite that fell in 1998 in Portugal. History During the night between 27 and 28 December 1998, a brilliant fireball and loud noises were reported by several people in Beja region.

Key takeaways

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

Reference excerpt

Ourique is a H4 meteorite that fell in 1998 in Portugal.

History During the night between 27 and 28 December 1998, a brilliant fireball and loud noises were reported by several people in Beja region. António Silva recovered the first fragments two days after the fall and, subsequently, local villagers recovered other pieces. The meteorite made an elliptical crater 20 centimetres (7.9 in) deep, 60 centimetres (24 in) long and 30 centimetres (12 in) wide. Most of all fragments were found within an elliptical area long 55 metres (180 ft).

Composition and classification It is a H4 type ordinary chondrite with a well-developed chondritic structure. Chemical analysis reported: olivine Fa18.3 and pyroxene Fs16.4.

Worked examples

Example 1 — a first encounter with Ourique (meteorite)

Start with the simplest possible case. Write down what Ourique (meteorite) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 Ourique (meteorite) 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 Ourique (meteorite) 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 Ourique (meteorite)

In research: Ourique (meteorite) appears in 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 Ourique (meteorite) 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: Ourique (meteorite) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1998 in Portugal, 1998 in science, Chondrite meteorites, so understanding it makes those chapters shorter.
In everyday life: Look for Ourique (meteorite) 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.
