How Are Solar Flares Different From Solar Prominences?
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 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.
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.
Do solar flares cause prominences?
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.
How are sunspots and solar flares similar quizlet?
How are sunspots and solar flares similar? How are they different? Sunspots are small cool dark spots that can be seen in the Sun’s photosphere they can last for a few weeks. Solar flares are extremely hot explosions into the Sun’s atmosphere the human eye can not see them.
What are solar prominences?
What is the difference between solar flares and coronal mass ejection?
What are solar flares?
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.
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.
Why do solar prominences occur?
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 are sunspots prominences and flares?
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.
What do we mean by solar activity describe sunspots prominences flares and coronal mass ejections?
Describe some of the features of solar activity including sunspots solar prominences solar flares and coronal mass ejections. Magnetic fields create features on the Sun’s surface and atmosphere. … Coronal mass ejections are when huge bubbles of charged particles from flares or other solar storms escape from the Sun.
Do sunspots originate from solar flares?
A sunspot is a cooler and therefore darker region of the Sun’s photosphere caused by a solar magnetic disturbance. Strong dense magnetic fields generated by circulating plasma sometimes become entangled and surge through the photosphere creating the sunspot.
What killed the Apollo 1 astronauts quizlet?
The Apollo 1 astronauts died during a fire on the launch pad the Challenger astronauts died shortly after launch still low in the atmosphere the Columbia crew and one of the early Soyuz crews died during re-entry.
Which zone 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 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.
What’s the definition of prominences?
: the state of being important well-known or noticeable : the state of being prominent.
How are solar prominences made?
What is the main difference between a solar flare and a CME?
Briefly solar flare is a radiation event observed in the continuous spectrum of X-rays and CME is an event that emits particles (electrons protons etc.). Therefore the main difference between them is the speed (Flare with speed = c and CME with speed from 400 to 1500 Km/s ).
What are the different classes of solar flares?
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. These are logarithmic scales much like the seismic Richter scale. So an M flare is 10 times as strong as a C flare.
What are solar flares made of?
How are solar prominences and filaments similar?
Which of the solar phenomena vary with the solar cycle?
Phenomena that vary with the solar-activity cycle are sunspots flares prominences coronal mass ejections and the corona itself (shape extent).
How do solar prominences affect Earth quizlet?
How do solar flares affect the Earth? … 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.
How do solar prominences affect communication?
Solar flares have been known to affect electronic communication because their energy stirs up the Earth’s upper atmosphere making radio broadcasts noisy and weak. The flares caused by violent storms on the Sun eject a stream of electrically-charged particles some of which reach the Earth.
What is a solar prominence NASA?
What is the difference between a quiescent prominence and an active prominence?
Active region prominences are defined as those having formed within the relatively strong magnetic field at the centers of active regions whereas in contrast quiescent prominences are defined as those having formed in the weak background field far from any active regions.
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 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 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 is a solar flare at what wavelengths is a solar flare observed?
Solar flares are categorized by the power in the 0.1–0.8 nm wavelength range in the X-ray part of the solar spectrum. The highest category of flare (X) has a power > 10−4 W m−2.
