What Is Responsible For The Mottled Appearance Of The Sun’s Surface Known As Granulation??
What is responsible for the mottled appearance of the Sun’s surface known as granulation. convection currents. Which of the following is true about the sun’s rotation. the sun rotates faster at its equator than it does at its poles. How much time passes between two successive sunspot minima.
What causes granulation quizlet?
d) the solar wind flowing away from the corona. e) the heating in the chromosphere. rising gas below photosphere. a) is hotter than the photosphere.
What is granulation in the Sun quizlet?
Granulation. The grainy appearance of the solar photosphere is produced by the tops of these convective cells and is called granulation. Solar Flare. An eruption of gas from the sun’s surface that occurs when the loops in sunspot regions suddenly connect: Similar to prominences but much quicker.
What are the dark regions that give the Sun’s photosphere a mottled appearance?
What does granulation tell us about the layers below the photosphere?
What does the granulation tell us about the layers below the photosphere? Since granules on the sun’s photosphere are constantly growing and shrinking astronomers can assume that convection currents are happening below it where the gas rises and falls due to heat.
What is granulation caused by?
What is the name of a sudden highly energetic eruptive surge on the surface of the Sun?
What causes the bubbling pattern of granulation that we see in the Sun’s photosphere?
the magnetic field of the Sun stops hot bubbles of gas from rising causing the region to cool off. … What is granulation in the Sun? the bubbling pattern on the photosphere produced by the underlying convection. What are (from granulation) granules?
What is the function of the chromosphere?
But the red rim can only be seen during a total solar eclipse. At other times light from the chromosphere is usually too weak to be seen against the brighter photosphere. The chromosphere may play a role in conducting heat from the interior of the sun to its outermost layer the corona.
Which of the following is used to refer to the surface of the Sun quizlet?
the Sun’s “Surface” – the part of the sun that emits the radiation we see – is called the photosphere. The sun’s radius is about 700 000 km.
What causes sunspots quizlet?
What causes sunspots? Magnetic fields breaking through the photosphere inhibit gas motion where the field is strong.
What makes the sun’s surface look mottled like an orange?
Carried by the Sun’s changing magnetic field a filament also known as a prominence of hot gas rose from the star’s surface. … The orange color is especially bright near the Sun’s surface but fainter wisps of orange also appear farther from the star.
Why does the sun emit neutrinos?
Neutrinos are born during the process of nuclear fusion in the sun. In fusion protons (the nucleus from the simplest element hydrogen) fuse together to form a heavier element helium. This releases neutrinos and energy that will eventually reach Earth as light and heat.
What is Sun photosphere?
What do granules tell us about the Sun?
You can observe so-called granules areas of about 1000 km in diameter where hot gas from inside the Sun rises to reach the surface of the Sun. As the gas cools down the gas slides down again into the Sun’s interior. The brighter regions indicate hot rising gas – the darker regions cool and down-welling gas.
How are astronomers able to explore the layers of the Sun below the photosphere?
How are astronomers able to explore the layers of the sun below the photosphere? … By observing solar X rays and gamma rays with space telescopes. These shorter wavelengths are emitted from hotter regions below the photosphere.
What does granulation tissue consist of?
The granulation tissue itself is made up of extracellular matrix proteoglycans hyaluronic acid collagen and elastin. Cytokines and growth factors interleukins and angiogenesis factors are active during this time which can continue anywhere from days to weeks under normal circumstances.
What happens granulation tissue?
In short observing granulation tissue in the bed of the wound means that the wound is progressing from the inflammatory phase of healing to the proliferative phase of healing. Several important cellular developments are occurring.
What is granulation quizlet?
Granulation tissue is best described as. Regeneration. replacement of damaged tissue by similar functional cells is termed. collagen fibers. Scar tissue consists primarily of.
What are the most energetic eruptive events to occur on the Sun quizlet?
What are the most energetic eruptive events to occur on the Sun? coronal mass ejections.
What are the most energetic eruptive events to occur on the Sun?
The origins of space weather are on the Sun where highly energetic explosive events occur in the form of flares and coronal mass ejections (CMEs). These events eject electrically charged particles and radiation into the heliosphere the region of space surrounding the Sun and including the planets of the solar system.
What are sun spots?
What mechanisms do astronomers believe are responsible for making the Sun’s outer atmosphere so much hotter than its photosphere?
What mechanisms do astronomers believe is responsible for making the Sun’s outer atmosphere so much hotter than its photosphere? The Sun’s magnetic field interacting with the charged particles that make up the atmosphere. Why do sunspots appear dark?
What is the visible surface of the Sun called?
Photosphere
Photosphere – The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that.Oct 10 2012
What is a fact about each layer of the Sun?
What is the chromosphere zone of the Sun?
What feature S does the chromosphere contribute to the solar spectrum?
A wavelength of 656.3 nm is in the red part of the spectrum which causes the chromosphere to have its characteristic reddish colour. By analysing the spectrum of the chromosphere it was found that the temperature of this layer of the solar atmosphere increases with height in the chromosphere itself.
What is the chromosphere of the Sun made of?
What is caused by the effect known as limb darkening?
Such limb darkening occurs because the solar atmosphere increases in temperature with depth. At the centre of the solar disk an observer sees the deepest and warmest layers that emit the most light. At the limb only the upper cooler layers that produce less light can be seen.
What causes the cycle of solar activity quizlet?
What causes the cycle of solar activity? Changes in the organization of the Sun’s magnetic field. … The time between eclipses and the average distance between the stars is needed.
What causes the cycle of solar activity?
What causes the cycle of solar activity? … Changes in the organization of the Sun’s magnetic field. How does the number of neutrinos passing through your body at night compare with the number passing through your body during the day? about the same.
What is the cellular granulation pattern seen on the visible surface of the Sun quizlet?
What is the explanation for the bright cells of photospheric gases that make up the cellular granulation pattern seen on the visible surface of the Sun? The cells are the tops of blobs of hot gas that have risen from the Sun’s convective zone.
What is a Plage quizlet?
A plage is a bright region in the chromosphere of the Sun typically found in regions of the chromosphere near sunspots. Coronal Mass Ejection. the most energetic of all solar eruptions which blasts plasma out from the corona and is followed by a solar flare.
What is the common cause of sunspots?
Sunspots occur over regions of intense magnetic activity and when that energy is released solar flares and big storms called coronal mass ejections erupt from sunspots.
