what gives this large prominence its unique shape

What Gives This Large Prominence Its Unique Shape? 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).

What is prominence caused by? 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 is a prominence in the solar surface? solar prominence, dense cloud of incandescent ionized gas projecting from the Sun’s chromosphere into the corona. Prominences sometimes extend hundreds of thousands of kilometres above the Sun’s chromosphere. Their causes are uncertain but probably involve magnetic forces.

What shape does a prominence usually take? A prominence, sometimes referred to as a filament, is a large plasma and magnetic field structure extending outward from the Sun’s surface, often in a loop shape.

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 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 is a prominence eruption?

A relatively large prominence erupted near the northeast solar limb during the afternoon hours of 23 October. Solar prominences are clouds of charged particles (“plasma”) above the solar surface squeezed between magnetic regions of opposite polarity.

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.

How big is a solar prominence?

According to Chaisson & McMillan, the size of a typical solar prominence is on the order of 100,000 km or around 10 times the diameter of Earth. Larger ones can reach a half-million kilometers. Prominences can show surges in time scales of hours, but the quiescent ones can persist for days or weeks.

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 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 a prominence in anatomy?

Medical Definition of prominence : an elevation or projection on an anatomical structure (as a bone)

What is the difference between prominence and solar flare?

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.

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.

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.

How do prominences affect Earth?

Prominences are associated with the release of high energy particles, known as a solar flare. As CMEs and prominences impact Earth, Earth’s magnetosphere may be disrupted through reconnection and/or compression, resulting in geomagnetic storms.

What is a prominence 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 do prominences give visual evidence of?

Erupting prominences provided the first observed evidence of expulsion of mass into the higher coronal regions.

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 part of the Sun produces the most amount of heat and light?

The core is the only part of the sun that produces an appreciable amount of heat through fusion. In fact, 99% of the energy produced by the sun takes place within 24% of the sun’s radius.

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

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.

Why is the sun huge today?

The Sun looks bigger than other stars because it is so much closer to the Earth. The further away an object is, the smaller it appears, even if it is very big.

How is a solar prominence 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. 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.

Is the sun more active?

The activity of the Sun over the last 11,400 years, i.e., back to the end of the last ice age on Earth, has now for the first time been reconstructed quantitatively by an international group of researchers led by Sami K.

What is a prominence astronomy quizlet?

prominence. A loop of gas that protrudes from the sun’s surface, linking parts of sunspot regions. sunspots.

What is the difference between a flare and a prominence 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.
