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 are sunspots related to prominences and solar flares?
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.
Prominences are usually associated with regions of sunspot activity, and are clearly associated with the Sun’s magnetic field.
What do sunspots have to do with solar flares?
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.
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.
What are both solar flares and prominences associated with?
Such violent events are called solar flares. Solar prominences are typically observed to be high loops of hot ionized gases which follow the geometry of the magnetic fields associated with pairs of sunspots.
What is the difference between Sun flares and prominences?
A prominence, seen from above and set against the Sun’s bright surface, appears as a dark filament. We also went over flares. 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.
How do solar flares affect 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.
What is the solar wind in which region does this wind originate?
The solar wind is a stream of charged particles released from the upper atmosphere of the Sun, called the corona. This plasma mostly consists of electrons, protons and alpha particles with kinetic energy between 0.5 and 10 keV.
How do solar prominences form?
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 sunspots related to the aurora borealis?
Sunspots, located in the Sun’s photosphere layer, are not the only phenomena that are responsible for Northern Lights. The Sun’s outermost layer, known as the ‘corona’, also does its bit to bring about Auroras.
What are solar prominences?
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.
Where do sunspots occur on the Sun?
Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere. The photosphere has a temperature of 5,800 degrees Kelvin.
What causes sunspots quizlet?
What causes sunspots? Magnetic fields breaking through the photosphere inhibit gas motion where the field is strong.
What are sunspots quizlet?
A sunspot is a region on the Sun’s photosphere that is cooler and darker than the surrounding material. Sunspots often appear in pairs or groups with specific magnetic polarities that indicate electromagnetic origins.
Do solar flares originate in sunspots?
A solar flare is an intense burst of radiation coming from the release of magnetic energy associated with sunspots.
What causes sunspots flares and prominences?
Sunspots are areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun’s surface. 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.
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.
How are solar flares caused?
A flare appears as a sudden, intense brightening of a region on the Sun, typically lasting several minutes. Flares occur when intense magnetic fields on the Sun become too tangled. Like a rubber band that snaps when it is twisted too far, the tangled magnetic fields release energy when they “snap”.
How are sunspots and Space Weather connected?
These unusual regions most often produce solar flares. Space weather forecasters use the complexity and shapes of sunspots to make flare forecasts-the more complex the groups of spots, the more likely a flare will occur.
Are solar flares and CMEs the same?
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.
Are solar flares the same as solar wind?
Solar winds constantly occur due to the corona of the sun continually expanding, but solar flares coincide with the sun’s 11-year cycle. At the start of a solar cycle, the sun’s magnetic field is weak, leading to fewer solar flares.
How is the solar activity cycle related to the sunspot cycle?
The 11-year sunspot cycle is actually half of a longer, 22-year cycle of solar activity. Each time the sunspot count rises and falls, the magnetic field of the Sun associated with sunspots reverses polarity; the orientation of magnetic fields in the Sun’s northern and southern hemispheres switch.
How can solar flares affect Earth quizlet?
How can solar flares affect Earth? They emit large amount of X-rays and ultraviolet radiation that travel to Earth and increase the ionization of Earth’s upper atmosphere. Flares also emit large amounts of charged particles that are caught by Earth’s magnetic field.
Does the Sun have corona?
The corona is the outer atmosphere of the Sun. It extends many thousands of kilometers (miles) above the visible “surface” of the Sun, gradually transforming into the solar wind that flows outward through our solar system. The material in the corona is an extremely hot but very tenuous plasma.
What is solar wind quizlet?
Solar Wind. A stream of electrically charged particles that flow outward from the Sun’s corona.
What does the solar wind cause in Earth’s atmosphere?
She explains in more detail how the solar wind disrupts our magnetosphere: “As the wind flows toward Earth, it carries with it the Sun’s magnetic field. It moves very fast, then smacks right into Earth’s magnetic field. The blow causes a shock to our magnetic protection, which can result in turbulence.”
What is a solar prominence quizlet?
Solar prominences. A glowing arch that reaches thousands of kilometers into the Sun’s atmosphere. They can last for a day to several months and are also visible during a total solar eclipse.
How do prominences affect Earth?
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 are flares on the Sun?
A solar flare is an intense localized eruption of electromagnetic radiation in the Sun’s atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other solar phenomena.
Why are sunspots cooler?
As well as being a darker area on the sun, a sunspot is an area that temporarily has a concentrated magnetic field. This magnetic force inhibits the convective motion, which ordinarily brings hot matter up from the interior of the sun, so the area of the sunspot is cooler than the surrounding plasma and gas.
Do solar flares cause aurora?
FORT WAYNE, Ind. (WPTA) ” The Aurora Borealis also known as the Northern Lights may be visible across Indiana and Ohio tonight after a strong solar flare erupted from the sun Monday.
How many sunspots are on the sun?
At Solar Maximum, there will be up to 200 sunspots on the Sun at one time.
Whats the definition of sunspots?
Definition of sunspot : any of the dark spots that appear at times on the sun’s surface and are usually visible only through a telescope.
Do solar flares cause heat waves?
Solar flares don’t cause heat waves, but they do have other impacts on Earth. Consequences include pretty auroras, as well as hazards.
Do sunspots occur in pairs?
Sunspots generally appear in opposite-polarity pairs or in opposite-polarity groups when the magnetic field is fractured.
What is a sunspot and how often do they occur?
Sunspot Number We know that sunspot counts generally rise and fall every 11 years on the average. Interestingly, sunspots often appear in pairs that are aligned in an east-west direction. One set will have a positive or north magnetic field while the other set will have a negative or south magnetic field.
What processes are involved in the sunspot cycle?
Which of the following processes is involved in the sunspot cycle? The winding of magnetic field lines due to the Sun’s rotation. helium, gamma rays, and neutrinos. Based on its surface temperature of 6,000 K, most photons that leave the Sun’s surface lie in which region of the electromagnetic spectrum?
What causes sunspots to move?
As the sunspots are a result of magnetic processes in the Sun, they move in the direction of its magnetic field lines. As shown in Figure 9 the Sun’s magnetic field lines are extended parallel to the Page 14 equator and become twisted. Therefore, sunspots move mainly parallel to the equator.
Where is the Sun’s energy produced?
Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy.
What is affected by the sunspot cycle quizlet?
The sunspot cycle affects. the latitude at which sunspots are visible at a given time. the number of sunspots that are visible at a given time. the magnetic polarity of the sunspots at a given time. The sun’s magnetic field is evident in the looped shapes of.
What is the Sun made of by mass quizlet?
What is the Sun made of? How do we know this? The sun is made of 71% hydrogen, 27% helium, and 2% heavier elements (carbon and oxygen).
What is the relationship between Earth’s temperature and the number of sunspots that occur quizlet?
What is the relationship between Earth’s temperature and the number of sunspots that occur? An increased number of sunspots causes an increase in Earth’s temperature.
How are sunspots related to prominences and solar flares?
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.
What do sunspots solar flares and solar prominences 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.
How do sunspots affect global warming?
Sunspots have been observed continuously since 1609, although their cyclical variation was not noticed until much later. At the peak of the cycle, about 0.1% more Solar energy reaches the Earth, which can increase global average temperatures by 0.05-0.1″. This is small, but it can be detected in the climate record.
