List of extraterrestrial volcanoes

List of extraterrestrial volcanoes 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 List of extraterrestrial volcanoes rather than just read about it. In short: This is a list of active, dormant, and extinct volcanoes located beyond planet Earth. They may be designated mons (mountain), patera (an irregular crater) or tholus (small mountain or hill) in accordance with the International Astronomical Union's rules for planetary nomenclature.

Key takeaways

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

Reference excerpt

This is a list of active, dormant, and extinct volcanoes located beyond planet Earth. They may be designated mons (mountain), patera (an irregular crater) or tholus (small mountain or hill) in accordance with the International Astronomical Union's rules for planetary nomenclature. Many of them are nameless.

Io, a moon of the planet Jupiter, is the most volcanically active body in the Solar System. Its volcanoes are believed to eject sulfur and sulfur dioxide, as well as basaltic and ultramafic silicate lavas.

Mars

Mars has many shield volcanoes, including the largest known volcano of the Solar System, but they are all dormant if not extinct. The most famous of these volcanoes is Olympus Mons, which is the largest known volcano in the Solar System.

Venus

On Venus, volcanic features are very numerous and quite diverse, but, like on Mars, none are known to be currently active. These volcanoes range from several to several hundred kilometers in diameter; a majority of them are shield volcanoes. In addition, Venus has unusual types of volcanoes: pancake domes and scalloped margin domes. Most small volcanoes on Venus are nameless.

The Moon

Due to the low viscosity of most lunar lava, volcanic mountains were seldom created. Instead, basaltic lava flooded large areas, which became lunar maria. Shield volcanoes are known from a few areas on the Moon; they are called lunar domes. Some areas of the Moon are covered with a usually dark coating, which is interpreted as pyroclastic deposits. Sometimes they form a dark halo around rilles. See also:

Mercury

Many of Mercury's basins contain smooth plains, like the lunar mare, that are believed likely to be filled with lava flows. Collapse structures possibly indicative of volcanism have been found in some craters. Eleven volcanic domes were identified in Mariner 10 images, including a 1.4-km high dome near the centre of Odin Planitia.

Other planets and moons

Saturn's moon Enceladus has fissures that spew water which have been photographed erupting by NASA's Cassini–Huygens spacecraft. Reports from NASA's Cassini–Huygens mission indicate that Saturn's moon Titan probably has volcanoes that eject water (cryovolcanoes). Triton, a moon of the planet Neptune, has cryovolcanic geysers that are believed to eject nitrogen, dust, or methane compounds, as well as possible cryovolcanic features. Pluto has features that may be cryovolcanoes, including Wright Mons and nearby Piccard Mons.

Worked examples

Example 1 — a first encounter with List of extraterrestrial volcanoes

Start with the simplest possible case. Write down what List of extraterrestrial volcanoes 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 List of extraterrestrial volcanoes 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 List of extraterrestrial volcanoes 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 List of extraterrestrial volcanoes

In research: List of extraterrestrial volcanoes 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 List of extraterrestrial volcanoes 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: List of extraterrestrial volcanoes is common in secondary-school and first-year university syllabi. It links to neighbouring topics Extraterrestrial volcanoes, Lists of volcanoes, so understanding it makes those chapters shorter.
In everyday life: Look for List of extraterrestrial volcanoes 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.
