What Gives This Large Prominence Its Unique Shape

What Gives This Large Prominence Its Unique Shape?

Prominences are shaped by the Sun’s complex magnetic field often forming loops with each end “anchored” to the Sun’s surface (photosphere). Prominences are enormous extending for many thousands of kilometers (miles).

How does each solar prominence get its shape?

How does each solar prominence get its shape? It erupts from the sun’s surface but is pulled back down by the sun’s gravity forming a curve. What are the most violent of all solar disturbances? A sudden outward eruption of electrically charged particles such as electrons and protons.

What causes prominences in the Sun?

The prominence plasma flows along a tangled and twisted structure of magnetic fields generated by the sun’s internal dynamo. An erupting prominence occurs when such a structure becomes unstable and bursts outward releasing the plasma.

What is a prominence also known as?

A solar prominence (also known as a filament when viewed against the solar disk) is a large bright feature extending outward from the Sun’s surface. Prominences are anchored to the Sun’s surface in the photosphere and extend outwards into the Sun’s hot outer atmosphere called the corona.

What does a prominence look like on the Sun?

Quiescent prominences tend to emerge smoothly and subside much more slowly so they may be visible for several months. Prominences appear either as flame-coloured projections when the disk of the Sun is totally eclipsed or as dark ribbons (called filaments) when viewed through a spectroscope.

What is a prominence on the Sun quizlet?

A prominence is a solar prominence (also known as a filament when viewed against the solar disk) is a large bright feature extending outward from the Sun’s surface. Prominences are anchored to the Sun’s surface in the photosphere and extend outwards into the Sun’s hot outer atmosphere called the corona.

What causes prominences to join?

The energy heats gas on the Sun to millions of degrees Celcius causing the gas to erupt into space. A sudden release of energy occurs when prominences link together. This is what these eruptions are called. Solar flares cause solar wind particles to be released from the Corona into Earths upper atmosphere.

What does prominence mean?

Definition of prominence

1 : something prominent : projection a rocky prominence. 2 : the quality state or fact of being prominent or conspicuous. 3 : a mass of gas resembling a cloud that arises from the chromosphere of the sun.

What is the prominent gas that the Sun is made of?


Instead the sun is composed of layers made up almost entirely of hydrogen and helium. These gases carry out different functions in each layer and the sun’s layers are measured by their percentage of the sun’s total radius.

What are the two types of prominences and their differences?

There are two basic types of prominences: (1) quiescent or long-lived and (2) transient. The former are associated with large-scale magnetic fields marking the boundaries of unipolar magnetic regions or sunspot groups.

What is prominence in phonetics?

Prominence (phonetics) stress given to a certain syllable in a word or to a word in a sentence.

What is the form of prominent?

Also prom·i·nen·cy. the state of being prominent conspicuousness. something that is prominent a projection or protuberance: a prominence high over a ravine.

What does achieved prominence mean?

In movies music and sports the most successful people have great prominence — they’re prominent or famous. Anything that juts out or sticks out has prominence. Whether prominence comes from being widely known or just being hard to miss you can’t really ignore anything or anybody that has achieved prominence.

What is the difference between a prominence and a filament?

When viewed spewing from the edge of the Sun against the darkness of space astronomers call the feature a prominence. But when seen against the background of the Sun from a different perspective the feature appears darker than its surroundings and is called a filament.

Why is the solar prominence important?

These prominences can last for days sometimes even months and are often associated with a very powerful surge of gas that flows outward in a giant solar “belch” — a coronal mass ejection that can light up Earth’s skies with an aurora and even interfere with our technology. For solar observers prominences are a joy.

How are sunspots and prominences related?

How are prominences and sunspots related? Sunspots are the lowest visible part of the magnetic disturbance and prominences are the higher arches. What happens as the bases of magnetic field loops are twisted? The loops reconnect and release energy into the upper atmosphere.

What is the difference between a prominence and a solar flare quizlet?

What is the difference between a prominence and a solar flare? A prominence is a loop of cool incandescent gas that extends above the photosphere. A solar flare is an explosive release of energy that comes from the sun and causes magnetic ditrubances.

What is the difference between a solar filament and a solar prominence quizlet?

Prominence and filament are emission of gas at chromosphere temperature above the surface of the Sun by a magnetic field. A bright loop or string like seen in a hydrogen emission just beyond the edge of the Sun is called Prominence. A filament is also like a prominence seen outcrop the solar disk.

What are the huge arching columns of gas that sometimes appear on the Sun’s surface called?

The most recognizable prominences appear as huge arching columns of gas above the limb of the Sun. Like sunspots prominences are cooler in relation to the much hotter background of the Sun’s outer atmosphere the corona. Prominences can erupt from the Sun with tremendous energy.

How do prominences differ from solar flares?

A prominence is a bright relatively dense and relatively cool arched cloud of ionized gas in the chromosphere and corona of the Sun. … A solar flare is a sudden brief (typically lasting only a few minutes) and explosive release of solar magnetic energy that heats and accelerates the gas in the Sun’s atmosphere.

What do prominences and solar flares have in common How are they different?

A typical solar flare may last from few minutes to few hours and can be observed as bright areas on the Sun. … A prominence is anchored to the Sun’s surface unlike a flare and is often characterized by a loop shape. A prominence is bound by the Sun’s magnetic field and can last for months.

What happens when prominences connect?

photosphere. These sun features are explosions of hot gas that occur when prominences connect. They shoot from the Sun’s surface releasing tremendous amounts of energy into space.

What does prominence mean in geography?

Definition: Prominence is a term in topography that refers to the elevation of a summit relative to its surrounding terrain. This is different from its overall elevation which measures the height of the summit above sea level.

What does special prominence mean?

1 distinguished set apart from or excelling others of its kind. 2 prenominal designed or reserved for a particular purpose. a special tool for working leather. 3 not usual or commonplace. 4 prenominal particular or primary.

What is prominence example?

Prominence is the state of being important being famous or being obvious. When an artist becomes famous and well-known this is an example of prominence. When a mountain is higher than the mountains around it this is an example of prominence. … Quiescent prominences form more smoothly and can last for several months.

What gas makes up space?

While hydrogen and helium make up most of the gases in interstellar space tiny traces of other elements such as carbon oxygen and iron also exist. Scientists who study interstellar space use spectrometers to identify trace amounts of other molecules between the stars.

What is responsible for the vast amount of heat and light produced by the sun?

The Sun produces light by a nuclear reaction called fusion. As atoms of hydrogen combine to form helium they produce vast amounts of heat and light.

How are photons created in the sun?

Fusion occurs in the sun’s innermost core when two atoms merge releasing energy and light in the process. Photons of light are first created in the sun’s center. Over tens of thousands of years the photons travel a “drunken walk ” zigzagging their way from atom to atom until they reach the surface.

Which statements describe prominences?

A prominence refers to a bright large gaseous feature projecting externally from the surface of the Sun usually in a loop shape. Prominences are attached with the surface of the Sun in the photosphere and elongate outwards into the corona of the Sun.

What was the shape of tongue of matter ejected from Sun?

11. What was the shape of tongue of matter ejected from sun ? Ans. Cigar shaped.

Do prominences look dark in regular photographs?

The pictures show ultraviolet light the hotter the temperature the brighter the light. Although the gas in a prominence is unimaginably hot by human standards it is actually cool compared to the Sun’s surface. Compared to the mottled yellow of the surface the filament looks dark.

What makes a syllable prominent?

Prominence is determined by a combination of factors including vowel length amplitude stress high pitch accents vocal quality and degree of vowel articulation (unstressed vowels tend to be reduced meaning they are pronounced closer to the relaxed mid central vowel ə (schwa).

What is prominence linguistics?

Prominence means that the element is perceived as standing out of the linguistic context. According to the standard definition prominence is a product of the length loudness pitch (and its movement) and quality of the designated element.

What is prominence in communication?

Prominence is marking of particular syllables as salient in English speech. This marking is accomplished by the pitch duration and intensity of the voice and is multi-functional in English.
