Volcanic plateau

Volcanic 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 Volcanic plateau rather than just read about it. In short: A volcanic plateau is a plateau produced by volcanic activity. There are two main types: lava plateaus and pyroclastic plateaus.

Key takeaways

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

Reference excerpt

A volcanic plateau is a plateau produced by volcanic activity. There are two main types: lava plateaus and pyroclastic plateaus.

Lava plateau Lava plateaus are formed by highly fluid basaltic lava during numerous successive eruptions through numerous vents without violent explosions (quiet eruptions). These eruptions are quiet because of the low viscosity of the lava and the small amount of trapped gases. The resulting sheet lava flows may be extruded from linear fissures or rifts or gigantic volcanic eruptions through multiple vents characteristic of the prehistoric era which produced giant flood basalts. Multiple successive and extensive lava flows cover the original landscape to eventually form a plateau, which may contain lava fields, cinder cones, shield volcanoes and other volcanic landforms. In some cases, a lava plateau may be part of a single volcano. An example is the massive Level Mountain shield volcano in northern British Columbia, Canada, which covers an area of 1,800 km2 (690 mi2) and a volume of 860 km3 (210 mi3). Perhaps the most extensive of all the subaerial basaltic plateaus existed during the Paleogene and possibly extended over 1,800,000 km2 (690,000 sq mi) of the northern Atlantic Ocean region. This region, known as the Thulean Plateau, is generally believed to have been broken up by the foundering of the Earth's crust to form the present ocean basin. Earth features numerous subaerial and submarine volcanic plateaus, such as the Columbia River Plateau (subaerial) and the vast Ontong Java Plateau (submarine).

Pyroclastic plateau Pyroclastic plateaus are produced by massive pyroclastic flows. They are underlain by pyroclastic rocks: agglomerates, tephra, volcanic ashes cemented into tuffs, mafic or felsic. Pyroclastic plateaus are also called ignimbrite plateaus. Examples include the Shirasu-Daichi, which makes up almost all of southern Kyūshū, Japan, and the North Island Volcanic Plateau in New Zealand.

Worked examples

Example 1 — a first encounter with Volcanic plateau

Start with the simplest possible case. Write down what Volcanic 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 Volcanic 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 Volcanic 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 Volcanic plateau

In research: Volcanic 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 Volcanic 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: Volcanic plateau is common in secondary-school and first-year university syllabi. It links to neighbouring topics Volcanic landforms, Volcanic plateaus, so understanding it makes those chapters shorter.
In everyday life: Look for Volcanic 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.

Frequently asked questions

What is Volcanic plateau in simple terms?

A volcanic plateau is a plateau produced by volcanic activity. There are two main types: lava plateaus and pyroclastic plateaus.

Why does Volcanic plateau 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 Volcanic plateau?

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.
