What Is The Common 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.

What is the common cause of sunspots?

Sunspots occur over regions of intense magnetic activity and when that energy is released solar flares and big storms called coronal mass ejections erupt from sunspots.

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 two main occurrences cause sunspots?

Sunspots are caused by the Sun’s magnetic field welling up to the photosphere the Sun’s visible “surface”. The powerful magnetic fields around sunspots produce active regions on the Sun which often lead to solar flares and Coronal Mass Ejections (CMEs). The solar activity of flares and CMEs are called “solar storms”.

Where do solar flares and prominences occur?

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 causes activity sunspots flares and loops in the Sun?

Sunspots form because loops of the Sun’s magnetic field break through the surface. Sunspots usually occur in pairs. The loop breaks through the surface where it comes out of the Sun. It breaks through again where it goes back into the Sun.

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.

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 causes a prominence?

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!

How are CMEs solar prominences and solar flares similar?

“Sometimes they occur together but they are not the same thing.” CMEs are giant clouds of particles from the Sun hurled out into space while flares are flashes of light—occurring in various wavelengths—on the Sun.

How are solar prominences related to sunspots?

Sunspots occur in pairs because each is one side of a loop of the Sun’s magnetic field that reaches the Sun’s surface. … Solar prominences are the plasma loops that connect two sunspots.

What causes sunspots quizlet?

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

What effect do solar flares have on earth?

Solar flares strongly influence the local space weather in the vicinity of the Earth. They can produce streams of highly energetic particles in the solar wind known as solar particle events. These particles can impact the Earth’s magnetosphere and present radiation hazards to spacecraft and astronauts.

When prominences join they cause sunspots solar flares?

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 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 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.

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 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.

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 a CME?

Coronal Mass Ejections (CMEs) are large expulsions of plasma and magnetic field from the Sun’s corona. … This can result in the sudden release of electromagnetic energy in the form of a solar flare which typically accompanies the explosive acceleration of plasma away from the Sun – the CME.

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.

What causes Coronalholes?

Coronal holes occur when the Sun’s magnetic field is open to interplanetary space. Conversely in regions where the solar magnetic fields loop back to the Sun forming arches X-ray and UV images show bright areas.

What does solar flares mean in science?

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. … Scientists classify solar flares according to their brightness in the x-ray wavelengths.

Do solar flares cause prominences?

Most often these eruptions are in the form of loops and sheets called prominences which remain under the control of the intense magnetic fields associated with solar storms. There are other events which in a matter of minutes can release enormous amounts of energy and eject material out into space.

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 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 causes the cycle of solar activity?

What causes the cycle of solar activity? … Changes in the organization of the Sun’s magnetic field. How does the number of neutrinos passing through your body at night compare with the number passing through your body during the day? about the same.

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.

Do solar flares cause global warming?

Patterns of solar irradiance and solar variation has been a main driver of climate change over the millennia to gigayears of the geologic time scale but its role in the recent warming has been found to be insignificant.
