Piemont-Liguria Ocean

Piemont-Liguria Ocean 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 Piemont-Liguria Ocean rather than just read about it. In short: The Piemont-Liguria basin or the Piemont-Liguria Ocean (sometimes only one of the two names is used, for example: Piemonte Ocean) was a former piece of oceanic crust that is seen as part of the Tethys Ocean. Together with some other oceanic basins that existed between the continents Europe and Africa, the Piemont-Liguria Ocean is called the Western or Alpine Tethys Ocean.

Key takeaways

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

Reference excerpt

The Piemont-Liguria basin or the Piemont-Liguria Ocean (sometimes only one of the two names is used, for example: Piemonte Ocean) was a former piece of oceanic crust that is seen as part of the Tethys Ocean. Together with some other oceanic basins that existed between the continents Europe and Africa, the Piemont-Liguria Ocean is called the Western or Alpine Tethys Ocean.

Plate tectonic history

The Piemont-Liguria Ocean was formed in the Jurassic period, when the paleocontinents Laurasia (to the north, with Europe) and Gondwana (to the south, with Africa) started to move away from each other. The oceanic crust that formed in between the two continents became the Piemont-Liguria Ocean. In the Cretaceous period the Piemont-Liguria Ocean lay between Europe (and a smaller plate called the Iberian plate) in the northwest and the Apulian plate (a sub-plate of the African tectonic plate) in the southeast. When the Apulian plate started moving to the northwest in the late Cretaceous, Piemont-Ligurian crust began to subduct beneath it. In the Paleocene the Piemont-Ligurian Ocean had completely disappeared under the Apulian plate and continental collision started between Apulia and Europe, which would lead to the formation of the Alps and the Apennines in the Tertiary.

Remains Fragments of Piemont-Ligurian oceanic crust were preserved as ophiolites in the Penninic nappes of the Alps and the Tuscan nappes of the Apennines. These nappes were subducted, sometimes to great depths in the mantle, before being obducted again. Due to the high pressures at these depths, much of the material had been metamorphosed in the blueschist or eclogite facies.

Worked examples

Example 1 — a first encounter with Piemont-Liguria Ocean

Start with the simplest possible case. Write down what Piemont-Liguria Ocean 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 Piemont-Liguria Ocean 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 Piemont-Liguria Ocean 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 Piemont-Liguria Ocean

In research: Piemont-Liguria Ocean 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 Piemont-Liguria Ocean 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: Piemont-Liguria Ocean is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cretaceous paleogeography, Geology of Austria, Geology of Switzerland, so understanding it makes those chapters shorter.
In everyday life: Look for Piemont-Liguria Ocean 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.
