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 do sunspots solar prominences and solar flares have in common?
What do sunspots, solar prominences, and solar flares all have in common?
They all have about the same temperature
. They are all strongly influenced by magnetic fields on the Sun. They are all shaped by the solar wind.
How are solar flares and prominences alike?
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.
Which do solar flares and coronal mass ejections have in common?
Which do solar flares and coronal mass ejections have in common? …
They are caused by the sun’s changing magnetic field
. They are explosive events that can affect Earth. This sentence explains the production and movement of energy in the sun and the flow of energy from the sun to Earth.
How are prominences different from solar flares quizlet?
A prominence is a loop of relatively cool, incandescent gas, while a solar flare is an explosive release of energy. Therefore prominences are cool,
while solar flares are hot
.
What is the difference between a CME and a solar flare?
CMEs are huge light bulb-shaped structures that propagate away from the Sun expanding as they travel through the interplanetary space. Flares, on the other hand
are smaller in size and more more sudden
.
What is the difference between solar wind and solar flare?
Frequency. Solar winds constantly occur due to the corona of the sun continually expanding, but solar flares coincide with the
sun’s 11-year
cycle.
What is the relationship between sunspots and solar flares?
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.
How long do solar prominences last?
Prominences can last
for several days – or up to several months
! Some prominences erupt and break apart, giving rise to coronal mass ejections (CME). Sometimes we see prominences against the bright background of the Sun itself, instead of at the edge of the Sun’s disk.
What causes the cycle of solar activity?
The solar cycle affects activity on the surface of the Sun, such as sunspots which are caused by
the Sun’s magnetic fields
. As the magnetic fields change, so does the amount of activity on the Sun’s surface. … The beginning of a solar cycle is a solar minimum, or when the Sun has the least sunspots.
Do solar flares affect humans?
Solar storms emit radiations, exposure to which is harmful to humans and can cause organ damage, radiation sickness and cancer. Most experts state that
there’s no significant risk to humans on the ground from solar flare
.
What happens if a solar flare hits Earth?
If the ejection is in the direction of the Earth, particles associated with this
disturbance can penetrate into the upper atmosphere (the ionosphere) and cause bright auroras
, and may even disrupt long range radio communication. It usually takes days for the solar plasma ejecta to reach Earth.
What causes solar flares quizlet?
A solar flare is a rapid variation in brightness seen on the sun. It occurs
when magnetic energy built up in the solar atmosphere is released in huge magnetic loops called solar prominences
.
What are some of the damages that can occur with solar flares quizlet?
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.
What is a possible cause of solar prominences?
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
.
