What Is A Prominence On The Sun Quizlet


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 are flares and prominences from the sun?

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 does the spectrum of a prominence reveal?

What does the spectrum of a solar prominence reveal? … By measuring and modeling the modes of vibration of the sun’s surface. The sun’s atmospheric layers are all less dense than its interior.

What is the primary difference between a prominence and a flare group of answer choices?

Flares – a solar flare is sudden fast and intense variation in brightness seen on Sun. Solar flare is a result of magnetic field. 3. Prominences – it is a large bright and gaseous feature which extends outwards from the Sun’s surface and falls back on it.

When two prominences connect it is called what?

solar flare. 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. A) solar flares.

What is prominence in the Sun?

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 are prominences?

Prominences are clouds of incandescent ionized gas ejected from the Sun’s surface. They are also some of the most dramatic phenomena in the solar system the equivalent of thousand-mile-high storms that can rage for months.

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 hot is a solar prominence?

The temperature of prominences is 5 000–50 000 K.

How does a solar prominence affect the earth?

The solar flare aspect of a prominence has the most common effect on the earth. Normally the magnetic field surrounding earth deflects harmful solar radiation. … Once detected they take minutes to a few hours to reach the planet. Their most common effect is on radar long-range radio and communications satellites.

What are some differences between solar flares and prominences on the sun?

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 is a solar flare or prominence )? Quizlet?

1. A solar flare is a rapid variation in brightness seen on the sun. Solar Flare Pt. 2. It occurs when magnetic energy built up in the solar atmosphere is released in huge magnetic loops called solar prominences.

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

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.

What causes prominences on the sun?

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 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.

How often do solar prominences occur?

They form over timescales of about a day and may persist in the corona for several weeks or months looping hundreds of thousands of kilometers into space.

What is prominence mountain?

Definition: Prominence is a term in topography that refers to the elevation of a summit relative to its surrounding terrain. … This is because the surrounding Alps are all tall mountains so you would have started at a much higher elevation than if you had hiked up from sea level.

What are sunspots on the Sun?

Sunspots are areas where the magnetic field is about 2 500 times stronger than Earth’s much higher than anywhere else on the Sun. Because of the strong magnetic field the magnetic pressure increases while the surrounding atmospheric pressure decreases.

What is a prominence in anatomy?

(prŏm′ə-nəns) Anatomy A small projection or protuberance.

What causes solar flares and prominences to occur?

Solar flares are a sudden explosion of energy caused by tangling crossing or reorganizing of magnetic field lines near sunspots. The surface of the Sun is a very busy place. It has electrically charged gases that generate areas of powerful magnetic forces. These areas are called magnetic fields.

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.

Which statements describe prominences?

Prominences are composed of cool dense gas. Prominences can disturb radio communications on Earth. Prominences are loop shaped.

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.

Which of these is the most likely impact of solar prominence on Earth?

Answer: Loss of electrical power generation. Explanation: This is because some prominences break apart and may then give rise to coronal mass ejections which will cause far more damages to the electrical power being used on earth.

What will the sun be when it runs out of heat?

Once all the helium disappears the forces of gravity will take over and the sun will shrink into a white dwarf. All the outer material will dissipate leaving behind a planetary nebula. “When a star dies it ejects a mass of gas and dust — known as its envelope — into space.

How many Earths can fit in the sun?

1.3 million Earths
If you divide the volume of the sun by the volume of the Earth you get that roughly 1.3 million Earths can fit inside the sun.

Which of the following best describes a solar prominence?

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.

Why do the sunspots appear dark?

Sunspots are “dark” because they are cooler than their surroundings. … Sunspots have a lighter outer section called the penumbra and a darker central region named the umbra. Sunspots are caused by disturbances in the Sun’s magnetic field welling up to the photosphere the Sun’s visible “surface”.

Are there sunspots today?

What happens when prominences join?

Loops in sunspot regions (prominences) sometimes suddenly connect releasing large amounts of magnetic energy. 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.

What are solar prominences for kids?

A solar prominence (also known as a filament) is an arc of gas that erupts from the surface of the Sun. Prominences can loop hundreds of thousands of miles into space. Prominences are held above the Sun’s surface by strong magnetic fields and can last for many months.

What part of the Sun is the hottest?

Core. The hottest part of the Sun is the core at 28 080 000°F on average.Mar 27 2009

What effect do solar flares have on Earth quizlet?

Particles from solar flares can distort Earth’s magnetic field which in turn disrupts navigation systems cause surges in electrical systems causing damage and blackouts and damage or disrupt satellites.

What are solar flares?

A solar flare is a tremendous explosion on the Sun that happens when energy stored in ‘twisted’ magnetic fields (usually above sunspots) is suddenly released.
