Maud Rise

Maud Rise 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 Maud Rise rather than just read about it. In short: The Maud Rise (66°S 3°E) is an oceanic plateau, which rises, at its shallowest, to depths of about 1,000 meters. It is located in the Weddell Sea in the Southern Ocean.

Key takeaways

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

Reference excerpt

The Maud Rise (66°S 3°E) is an oceanic plateau, which rises, at its shallowest, to depths of about 1,000 meters. It is located in the Weddell Sea in the Southern Ocean. Its name was approved by the Advisory Committee for Undersea Features in June 1987.

Geology Maud Rise formed part of the south-eastern African large igneous province (LIP), which developed south of Africa 100 to 94 million years ago (Ma). This LIP first formed 140-122 Ma east of South Africa where the Mozambique Ridge is now located. There it reached a maximum extent around 120 Ma when the African-Antarctic spreading zone was located below its eastern flank. Astrid Ridge was possibly part of this LIP as well. The LIP formation then continued intermittently until it finally reached its maximum extent south of South Africa 100 Ma. This volcanism ended 94 Ma, after which seafloor spreading divided the LIP into the Agulhas Plateau (south of South Africa), Northeast Georgia Rise (near South Georgia Island off South America), and Maud Rise.

Worked examples

Example 1 — a first encounter with Maud Rise

Start with the simplest possible case. Write down what Maud Rise 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 Maud Rise 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 Maud Rise 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 Maud Rise

In research: Maud Rise 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 Maud Rise 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: Maud Rise is common in secondary-school and first-year university syllabi. It links to neighbouring topics Antarctica stubs, Large igneous provinces, Marine geography stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Maud Rise 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.

Frequently asked questions

What is Maud Rise in simple terms?

The Maud Rise (66°S 3°E) is an oceanic plateau, which rises, at its shallowest, to depths of about 1,000 meters. It is located in the Weddell Sea in the Southern Ocean.

Why does Maud Rise 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 Maud Rise?

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.
