What Is The Cause Of Sunspots Flares And Prominences??

What is the common cause of sunspots flares and prominences? The helium produced from the fusion of hydrogen has less mass than the hydrogen that goes into its formation. … roughly 200 000km in radius it is the sight of powerful nuclear fusion reactions that generate the sun’s enormous energy output.

What causes solar flares and prominences to occur?

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. … The formation of solar flares from the merging of magnetic fields is called a reconnection event.

What are the causes of sunspots?

Sunspots are caused by disturbances in the Sun’s magnetic field welling up to the photosphere the Sun’s visible “surface”. The powerful magnetic fields in the vicinity of sunspots produce active regions on the Sun which in turn frequently spawn disturbances such as solar flares and coronal mass ejections (CMEs).

What is the cause of prominences?

Prominences sometimes extend hundreds of thousands of kilometres above the Sun’s chromosphere. Their causes are uncertain but probably involve magnetic forces. … Prominences are clouds of incandescent ionized gas ejected from the Sun’s surface.

What are solar flares prominences and sunspots?

Solar prominences are the plasma loops that connect two sunspots. Solar flares and coronal mass ejections are eruptions of highly energetic particles that can erupt from the Sun’s surface and cause problems with power grids and communications on Earth.

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 are prominences on 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 do solar flares cause on Earth?

As more energy is released by a solar flare it can create shock waves that accelerate particles away from the sun causing what is known as a particle storm. These particles can reach Earth almost as fast as solar flares in less than an hour.

What causes sunspots quizlet?

What causes sunspots? Magnetic fields breaking through the photosphere inhibit gas motion where the field is strong.

What are prominences and sunspots?

Summary. Sunspots occur in pairs because each is one side of a loop of the Sun’s magnetic field that reaches the Sun’s surface. These spots are cooler and darker than the rest of the Sun’s surface and they are marked by intense magnetic activity. Solar prominences are the plasma loops that connect two sunspots.

How do solar flares affect the solar wind?

The solar wind can be strongly affected by solar flares and coronal mass ejections both of which fling huge amounts of coronal material and embedded magnetic fields into space. These ejected particles become a powerful “gust” in the solar wind. When they reach the earth they can cause severe space weather storms.

Where do solar flares occur?

the sun

Solar flares occur when a buildup of magnetic energy on the sun is suddenly released. They usually erupt from sunspots temporary dark and relatively cool patches on our star’s surface where the local magnetic field is very strong.

What will happen to the Earth when prominences solar flares and sunspots occur?

If a prominence breaks apart it produces a coronal mass ejection. 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. If not life would be impossible.

What causes solar flares and coronal mass ejections?

According to NASA a solar flare is an intense burst of radiation that comes from the release of magnetic energy linked with the sunspots. Coronal mass ejections or CMEs are massive clouds of particles that are pushed out into space from the Sun’s atmosphere.

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.

Where do prominences originate on the Sun?

photosphere

Prominences are anchored to the Sun’s surface in the photosphere and extend outwards into the Sun’s hot outer atmosphere called the corona. A prominence forms over timescales of about a day and stable prominences may persist in the corona for several months looping hundreds of thousands of miles into space.

What are solar flares?

Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground however — when intense enough — they can disturb the atmosphere in the layer where GPS and communications signals travel.

What causes solar wind?

The solar wind is created by the outward expansion of plasma (a collection of charged particles) from the Sun’s corona (outermost atmosphere). This plasma is continually heated to the point that the Sun’s gravity can’t hold it down. It then travels along the Sun’s magnetic field lines that extend radially outward.

What phenomenon occurs on Earth as a result of solar flares on the Sun?

What phenomenon occurs on Earth as a result of solar flares on the Sun? Northern lights.

What is the cause of the sunspot cycle on the sun quizlet?

What is the cause of the sunspot cycle on the Sun? Subsurface magnetic fields are twisted by the Sun’s differential rotation and break through the surface as sunspots then gradually cancel each other and return below the surface. … its very powerful magnetic field.

What do sunspots solar prominences solar flares and coronal mass ejections all have in common?

What do sunspots solar prominences and solar flares all have in common? They are all strongly influenced by magnetic fields on the Sun. – Sun has a very large and very complex magnetic field. – Solar magnetic field changes overtime and undergoes spontaneous reversals about every 11 years.

What causes the sun’s magnetic field to deform?

Electric currents inside the sun generate a magnetic field that spreads throughout the solar system. … The poles flip at the peak of the solar activity cycle every 11 years. A solar wind composed of charged particles carries the magnetic field away from the sun’s surface and through the solar system.

What is the difference between the 2 types of prominences?

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. Because the large unipolar plates are long-lived the quiescent prominences are as well.

How are sunspots related to solar storms?

If sunspots are active more solar flares will result creating an increase in geomagnetic storm activity for Earth. Therefore during sunspot maximums the Earth will see an increase in the Northern and Southern Lights and a possible disruption in radio transmissions and power grids.

Why does the sun create solar flares?

A solar flare is burst of radiation from the sun from the release of magnetic energy associated with sunspots according to NASA. Flares can last for minutes to hours and can be seen as bright spots on the sun from telescopes.

What produces solar flares quizlet?

A solar flare is a rapid variation in brightness seen on the sun. It occurs when magnetic energy built up in the solar atmosphere is released in huge magnetic loops called solar prominences. … Sunspots cause auroras communication blackouts and usually increased solar flare activity.

How are solar flares categorized?

Scientists classify solar flares according to their X-ray brightness in the wavelength range 1 to 8 Angstroms. Flares classes have names: A B C M and X with A being the tiniest and X being the largest. Each category has nine subdivisions ranging from e.g. C1 to C9 M1 to M9 and X1 to X9.

Do prominences cause auroras?

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.

Why do coronal mass ejections occur?

Bottom line: Coronal mass ejections – also knowns as CMEs – are powerful eruptions on the sun’s surface. Caused by instabilities in the sun’s magnetic field they can launch a billion tons of superheated gas into space. Most drift harmlessly across the solar system but occasionally one is aimed at Earth.

Can CME cause earthquakes?

Electromagnetic variations have been observed after earthquakes but despite decades of work there is no convincing evidence of electromagnetic precursors to earthquakes.

What’s the definition of prominences?

: the state of being important well-known or noticeable : the state of being prominent.

How is a solar prominence formed?

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). Prominences can last for several days – or up to several months!

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.

What is the difference between sunspots and solar flares?

Sunspots range from Earth-size “pimples” to swollen scars halfway across the surface. Sunspot activity generally follows an 11-year cycle called the “sunspot cycle.” A solar flare is a violent eruption of plasma from the chromosphere of the Sun that is whipped up by intense magnetic activity.
