What Evidence Do We Have That The Granulation Seen On The Sun’s Surface Is Caused By Convection??

What evidence do we have the granulation seen on the sun’s surface is caused by convection? The bright centers of granules are hotter than their dark boundaries AND doplar measurements indicate that the centers are rising and the edges are sinking.

What causes the granulation that is visible on the surface of the Sun?

Close-up views of the photosphere also show patterns of light areas surrounded by darker borders called “granulation.” Similar to the patterns you can see at the top of a pot of boiling water or oatmeal granulation is caused by heat rising upward to the photosphere from the hotter solar interior.

What causes granulation on the photosphere quizlet?

Granules on the photosphere of the Sun are caused by convection currents (thermal columns Bénard cells) of plasma within the Sun’s convective zone. The grainy appearance of the solar photosphere is produced by the tops of these convective cells and is called granulation.

Which of the following is evidence that convection occurs in layers just below the photosphere group of answer choices?

Which of the following is evidence that convection occurs in the layers just below the suns photosphere? The centers of granules are hot and moving upward away from the center of the sun. Helioseismology is the study of the differential rotation and magnetic field of the sun.

What is granulation how is it related to convection?

Thus granulation just represents the tops of convection currents that are transferring heat from below the solar surface to the surface. In that sense granules are a little like the tops of cumulus clouds in the Earth’s atmosphere which are also associated with convection currents.

What is granulation caused by?

They are caused by convection currents of plasma in the Sun’s convective zone directly below the photosphere. The grainy appearance of the solar photosphere is produced by the tops of these convective cells and is called granulation.

What are the three layers of the Sun’s atmosphere in order of increasing distance from the surface?

In order of increasing distance from the center of the Sun they are the photosphere with a temperature that ranges from 4500 K to about 6800 K the chromosphere with a typical temperature of 104 K the transition region a zone that may be only a few kilometers thick where the temperature increases rapidly from 104

Which of these layers of the Sun is coolest? photosphere chromosphere corona photosphere

What is responsible for the sunspots on the Sun’s surface?

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. … These areas are called magnetic fields.

Why granulation is required?

Why is Granulation Necessary? The granulation process allows particles to stick together more firmly. It increases the particle size of the constituents used which are mostly very fine powders. The greater the particle size of a constituent greater will be its compressive or binding ability.

What happens on the surface of the Sun?

The surface of the Sun heaves and boils as pockets of hot gas well up and sink back down. This gives the surface a grainy look which is known as granulation. Violent explosions called solar flares rip through the surface and giant fountainlike eruptions called prominences shoot super-hot gas far into space.

What evidence can you give that granulation is caused by convection quizlet?

The evidence for granulation being caused by convection is that convection is caused by the mottled appearance of the solar photosphere caused by gases rising from the interior of the Sun.

What is granulation in the Sun Group of answer choices?

The solar wind is ionized gas streaming away from the sun. Granulation is caused by convection. The temperature of the corona is millions of degrees. … Due to the required temperatures fusion occurs only in the core of the sun.

What is the reason that the evidence in Part B suggests the type of energy transport in Part A )?

What is the reason that the evidence in part (b) suggests the type of energy transport in part (a)? The sun gives off radiation. There is no evidence of the types of energy transport occurring in the sun. These features are at a much lower temperature than the rest of the photosphere.

What evidence do we have that the sunspots are magnetic?

What evidence do we have that sunspots are magnetic? The spectral lines of sunspots are split by the Zeeman Effect and observations at far ultraviolet show material arched above the sun’s surface from one sunspot to another.

Does the Sun have a solid surface and where or why not quizlet?

Does the Sun have a solid surface and where or why not? no it does not because the Sun is entirely a gas from its surface right to its center. We see more deeply into the Sun at its center than at its limb because of the interaction of the light with atoms of the gas.

In which part of the Sun’s atmosphere is the source of the Sun’s visible light?

photosphere
The photosphere is about 300 km thick. Most of the Sun’s visible light that we see originates from this region. The chromosphere is about 2000 km thick. We only see this layer and the other outer layers during an eclipse.

What does the 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 information is given in a Maunder butterfly diagram?

What information is given in a Maunder butterfly diagram? The location pattern of sunspots during a sunspot cycle with sunspots appearing at higher latitudes early in the cycle and closer to the equator later in the cycle.

What have modern observations shown sunspots to be?

Observations have shown sunspots to be relatively “cooler” areas of the Sun’s surface or photosphere connected with disturbances in the solar magnetic field. … Sunspots usually come in pairs and drift from the high latitudes of the Sun toward the equator.

How do observations of the Sun’s surface tell us about conditions in the solar interior?

How do observations of the Sun’s surface tell us about conditions in the solar interior? Observations of the Sun’s surface can tell us about the Sun’s differential rotation as well as see the oscillations of the Sun which are the result of vibrations from internal pressure waves.

Which layer of the Sun is where fusion occurs?

core

The Sun’s interior domain includes the core the radiative layer and the convective layer (Figure 2–1). The core is the source of the Sun’s energy the site of thermonuclear fusion.

What layer is what we see when we look up at the Sun?

The boundary between the Sun’s interior and the solar atmosphere is called the photosphere. It is what we see as the visible “surface” of the Sun. The photosphere is not like the surface of a planet even if you could tolerate the heat you couldn’t stand on it.

When astronomers describe granulation of the Sun What are they referring to?

(SA) Explain what the granulation of the solar surface is related to. The surface of the Sun is highly mottled or granulated. Each granule is about 1 000 km across. The granulation is produced by the convection (boiling) of the Sun’s gases.

Which layer shown has convection of plasma within it that leads to granulation of the photosphere?

Granules on the photosphere of the Sun are caused by convection currents (thermal columns Bénard cells) of plasma within the Sun’s convective zone. The rising part of the granules is located in the center where the plasma is hotter.

What causes the granular appearance of the surface of the Sun quizlet?

The cells are the tops of blobs of hot gas that have risen from the Sun’s convective zone. The granular appearance of the surface of the Sun is evidence of what phenomenon occurring in or on the Sun? Convection currents. Upward in the bright cell centers and downward around the darker edges.

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.
