Magellan Rise (ocean plateau)

Magellan Rise (ocean plateau) 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 Magellan Rise (ocean plateau) rather than just read about it. In short: Magellan Rise is an oceanic plateau in the Pacific Ocean, which covers a surface area of 500,000 square kilometres (190,000 sq mi). There is another geological structure with the same name west from the Marshall Islands.

Key takeaways

Magellan Rise (ocean plateau) 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 Magellan Rise (ocean plateau) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Magellan Rise (ocean plateau) from memory before moving on to harder problems.

Reference excerpt

Magellan Rise is an oceanic plateau in the Pacific Ocean, which covers a surface area of 500,000 square kilometres (190,000 sq mi). There is another geological structure with the same name west from the Marshall Islands. The Magellan Rise has been called a large igneous province by Coffin and Endholm 2001 and was emplaced 145 million or 135-128 million years ago, possibly as a consequence of intense volcanism at a former triple junction. Alternatively, the Rise was formed by a mantle plume linked to the deep "JASON superplume", or from the interaction of a spreading ridge with a plume. Candidate mantle plumes are the Easter hotspot and the Foundation hotspot. The volume of rocks in the Magellan Rise is very uncertain, but may be in the range of 1,800,000 cubic kilometres (430,000 cu mi) to 19,740,000 cubic kilometres (4,740,000 cu mi). It apparently developed first on the Phoenix Plate before being transferred onto the Pacific Plate 125 million years ago. The Magellan Rise has never risen to shallow depths, at least since the Cretaceous, and it is covered by sediments of Tithonian/Berriasian to Quaternary age. The sediments include chalk, chert, limestone (including fossil belemnites, molluscs and polychaetes), phosphorites and volcanic ash from the Ontong Java Plateau, which were emplaced during the Selli Event.

Worked examples

Example 1 — a first encounter with Magellan Rise (ocean plateau)

Start with the simplest possible case. Write down what Magellan Rise (ocean plateau) 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 Magellan Rise (ocean plateau) 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 Magellan Rise (ocean plateau) 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 Magellan Rise (ocean plateau)

In research: Magellan Rise (ocean plateau) 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 Magellan Rise (ocean plateau) 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: Magellan Rise (ocean plateau) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Oceanography stubs, Plateaus of the Pacific Ocean, Underwater ridges of the Pacific Ocean, so understanding it makes those chapters shorter.
In everyday life: Look for Magellan Rise (ocean plateau) 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.
