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.

What are solar sunspots?

Sunspots are temporary phenomena on the Sun’s photosphere that appear as spots darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic flux that inhibit convection. Sunspots appear within active regions usually in pairs of opposite magnetic polarity.

What is the relationship between Earth’s temperature and the number of sunspots that occur?

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. A decreased number of sunspots causes an increase in Earth’s temperature. An increased number of sunspots causes Earth’s temperature to remain constant.

What is the relationship between the number of sunspots and the increase in coronal mass ejections?

… Sunspot numbers are strongly correlated with solar activity such as X-ray flares. Increased numbers of solar flares and coronal mass ejections produce increased fluxes of high-energy solar particles during the maxima [13] [14][15].

What is the sun made of and how does its mass compare with the rest of the solar system?

It holds 99.8% of the solar system’s mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun. … The sun is relatively young part of a generation of stars known as Population I which are relatively rich in elements heavier than helium.

How much weight is the Earth?

5.972 × 10^24 kg

What is the difference between the mass of the sun and the mass of Jupiter?

Jupiter is about 0.001 as massive than the sun but it’s sizeable enough that both the sun and Jupiter orbit that point in space.

How do sunspots affect auroras?

Sunspots are formed when magnetic field fluctuations prevent heat transfer leading to areas of the sun’s surface being cooler than the sun as a whole. … This means that during periods of high sunspot activity auroras occur on Earth with greater strength and frequency due to increased solar wind output.

What is Arora?

The Arora is a community of Punjab comprising both Hindus and Sikhs. The name is derived from their native place Aror. Historically the Arora section of the Khatri community had been principally found in West Punjab in the districts to the south and west of Lahore.

Do solar flares cause aurora borealis?

When solar flares send floods of those particles towards the Earth that causes a geomagnetic storm which can produce particularly stunning auroras. … The inundation of solar particles can also interfere with power grids GPS and radio communications and even affect satellites’ orbits around Earth.

What is the main difference between a solar flare and a coronal mass ejection?

A: The main difference between solar flares and coronal mass ejections (CMEs) is the scale on which they occur. Solar flares are relatively small and local taking place in the low solar atmosphere near sunspots where magnetic field lines are concentrated. CMEs on the other hand are absolutely huge.

What is the difference between a solar flare and a CME?

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 is the effect of variations in the number of sunspots?

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.

What is the difference between a solar filament and a solar prominence quizlet?

Prominence and filament are emission of gas at chromosphere temperature above the surface of the Sun by a magnetic field. A bright loop or string like seen in a hydrogen emission just beyond the edge of the Sun is called Prominence. A filament is also like a prominence seen outcrop the solar disk.

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.

What is a solar flare or 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 sunspots look like?

What do they look like? Sunspots appear as flat darker patches of skin (tan to dark brown) that are found on areas of the body that have experienced high levels of sun exposure such as the face shoulders hands chest and the backs of hands.

What is the common cause of sunspots flares and prominences quizlet?

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.

Why do solar flares occur?

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”. … Solar flares burst forth from the intense magnetic fields in the vicinity of active regions on the Sun.

Is there a relationship between sunspot activity and global temperatures?

A significant correlation between sunspot cycle length and terrestrial global mean temperatures is found. However the results of this study do not support the claim that most of the recent warming is due to the Sun’s activity.

How does the number of sunspots on the Sun vary with time?

How does the number of sunspots on the Sun vary with time? The number of sunspots varies relatively regularly with a period of about 11 years. observing the wavelength splitting of atomic spectral lines by the Zeeman effect. hydrogen nuclei and electrons some He nuclei.

How do solar flares affect the amount of radiation emitted from the Sun?

The most powerful solar flares are huge bursts of x-rays and electrified hot gas called coronal mass ejections (CMEs) which hurl solar matter into space. … The explosion that creates the CME accelerates the protons around the Sun to nearly the speed of light.

How do solar flares affect the Earth?

X-rays and UV radiation emitted by solar flares can affect Earth’s ionosphere and disrupt long-range radio communications. Direct radio emission at decimetric wavelengths may disturb the operation of radars and other devices that use those frequencies.

How hot are solar flares?

As solar flares push through the corona they heat its gas to anywhere from 10 to 20 million K occasionally reaching as high as 100 million K. According to NASA the energy released in a solar flare “is the equivalent of millions of 100-megaton hydrogen bombs exploding at the same time.”

How does the sun compare to other stars?

The Short Answer:

Our Sun is an average sized star: there are smaller stars and larger stars even up to 100 times larger. Many other solar systems have multiple suns while ours just has one. Our Sun is 864 000 miles in diameter and 10 000 degrees Fahrenheit on the surface.

Will the sun ever burn out?

Eventually the fuel of the sun – hydrogen – will run out. When this happens the sun will begin to die. But don’t worry this should not happen for about 5 billion years. After the hydrogen runs out there will be a period of 2-3 billion years whereby the sun will go through the phases of star death.
