Which part of the Sun is more hot - interior or exterior ?

Answer 1

The interior of the sun is much hotter than its exterior. The outer layer called the photosphere has a temperature of 6000 degree Celsius. Where the core of the sun has the temperature 15,000,000 degree Celcius

Answer 2

interior
Although the Sun is gaseous, it can be seen only to the point at which the density is so high that the material is opaque. This layer, the visible surface of the Sun, is termed the photosphere. Light from father down reaches the Earth by repeated absorption and emission by the atoms, but the deepest layers cannot be seen directly. The surface is actually not sharp, but the Sun is so far away that the smallest distance that can be resolved with the best telescope is about 300 km (200 mi). Since the density e-folding height (scale height) is less than 200 km (120 mi), the edge appears sharp. See also Photosphere.

Above the photosphere the atmosphere is transparent, and its density falls off much more slowly because magnetic fields support the ionized particles. The atmosphere can be seen by using a narrow-band filter or a spectrograph to pick out the isolated wavelengths absorbed by the atmospheric gases. In the upper photosphere it is cooler, and the lines are dark. If the light is imaged in the strongest lines, such as those of hydrogen, a region higher still is seen, called the chromosphere. The light from this region is dominated by the red hydrogen alpha (level 2 → 3 transition) line, which gives it a rosy color seen at a solar eclipse. The chromosphere is a rapidly fluctuating region of jets and waves coming up from the surface. When all the convected energy coming up from below reaches the surface, it is concentrated in the thin material and produces considerable activity. Where the magnetic field is stronger, these waves are absorbed, and raise the temperature to 7000–8000 K (12,000–14,000°F). The scale height of the chromosphere is 1000 km (600 mi) or more, so there no longer is a sharp edge. See also Chromosphere; Eclipse.

When the Moon obscures the Sun at a total solar eclipse, the vast extended atmosphere of the Sun called the corona can be seen. The corona is a million times fainter than the photosphere, so it is visible only when seen against the dark sky of an eclipse or with very special instruments. Its density is low, but its temperature is high (more than 106 K or 1.8 × 106°F). The hot gas evaporating out from the corona flows steadily to the Earth and farther in the solar wind. See also Solar corona; Solar wind.


Coronal holes

Early coronal observations showed that the corona was occasionally absent over certain regions. In particular, at sunspot minimum it was quite weak over the poles. X-ray pictures revealed great bands of the solar surface essentially devoid of corona for many months. These proved to be regions where the local magnetic fields were connected to quite distant places, so the fields actually reached out to heights from which the solar wind could sweep the gas outward. Analysis of solar wind data showed that equatorial coronal holes were associated with high-velocity streams in the solar wind, and recurrent geomagnetic storms were associated with the return of these holes. Thus the relative intensity of the corona over sunspot regions is partly due to their strong, closed magnetic fields which trap the coronal gas.

Answer 3

Interior

Answer 4

Interior.

Answer 5

Interior,from the inside out.

Answer 6

Sun's interior part is hotter than exterior.

Answer 7

The solar's rays are very damaging to the motor vehicle's indoors. They reason fading, drying and cracking, fairly on the dashboard. If possible, get a sort of window colour issues (they are made up of cardboard and embellished with countless scenes or now and lower back coated with aluminum foil-type textile) and consistently use it while the motor vehicle is pointed on the solar. An extra earnings is that the interior will proceed to be cooler and you will not burn your decrease back, butt or palms once you enter the vahicle.

Answer 8

In the Sun's outer layer (down to approximately 30% of solar radius), the solar plasma is not dense enough or hot enough to transfer the heat energy of the interior outward via radiation. As a result, thermal convection occurs as thermal columns carry hot material to the surface (photosphere) of the Sun. Once the material cools off at the surface, it plunges back downward to the base of the convection zone, to receive more heat from the top of the radiative zone. Convective overshoot is thought to occur at the base of the convection zone, carrying turbulent downflows into the outer layers of the radiative zone.

The thermal columns in the convection zone form an imprint on the surface of the Sun, in the form of the solar granulation and supergranulation. The turbulent convection of this outer part of the solar interior gives rise to a "small-scale" dynamo that produces magnetic north and south poles all over the surface of the Sun.

he visible surface of the Sun, the photosphere, is the layer below which the Sun becomes opaque to visible light. Above the photosphere visible sunlight is free to propagate into space, and its energy escapes the Sun entirely. The change in opacity is due to the decreasing amount of H- ions, which absorb visible light easily. Conversely, the visible light we see is produced as electrons react with hydrogen atoms to produce H- ions. The photosphere is actually tens to hundreds of kilometers thick, being slightly less opaque than air on Earth. Because the upper part of the photosphere is cooler than the lower part, an image of the Sun appears brighter in the center than on the edge or limb of the solar disk, in a phenomenon is known as limb darkening. Sunlight has approximately a black-body spectrum that indicates its temperature is about 6,000 K, interspersed with atomic absorption lines from the tenuous layers above the photosphere. The photosphere has a particle density of about 1023 m−3 (this is about 1% of the particle density of Earth's atmosphere at sea level).

During early studies of the optical spectrum of the photosphere, some absorption lines were found that did not correspond to any chemical elements then known on Earth. In 1868, Norman Lockyer hypothesized that these absorption lines were because of a new element which he dubbed "helium", after the Greek Sun god Helios. It was not until 25 years later that helium was isolated on Earth.

Answer 9

Interior part is more hotter because the interior part contains radiation zone which releases gases of high temp.

Answer 10

Sun is more hotter from interior . Like the core of the earth . the earth is hotter from interior
