What is the function of the chromosphere?

The chromosphere may play a role in conducting heat from the interior of the sun to its outermost layer, the corona.

What happens in chromosphere?

The chromosphere is an irregular layer above the photosphere where the temperature rises from 6000°C to about 20,000°C. At these higher temperatures hydrogen emits light that gives off a reddish color (H-alpha emission).

What is the function description of the chromosphere How hot is it?

Chromosphere’s temperature ranges from 6,000 to 20,000 degree Celsius. The temperature rises as chromosphere moves farther away from the Sun unlike other objects of the solar system. … One of the important features of the chromosphere is the presence of spicules on its edges.

What 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.

Where is the chromosphere?

the Sun

Chromosphere – The chromosphere is a layer in the Sun between about 250 miles (400 km) and 1300 miles (2100 km) above the solar surface (the photosphere).

What is chromosphere physics?

The solar chromosphere (color sphere) is a strongly structured and highly dynamic region (layer) of the Sun’s atmosphere, located above the bright, visible photosphere. It is optically thin in the near-ultraviolet to near-infrared spectral range, but optically thick in the millimeter range and in strong spectral lines.

Where is the chromosphere of the Sun quizlet?

Where is the chromosphere on the Sun? It is the layer above the visible surface of the Sun.

What is the color of the chromosphere?

The Sun’s chromosphere appears as a rim of red light during a solar eclipse. The lower region of the Sun’s atmosphere is called the chromosphere. Its name comes from the Greek root chroma (meaning color), for it appears bright red when viewed during a solar eclipse.

What protects the earth from solar winds?

Earth’s magnetic field, or magnetosphere, stretches from the planet’s core out into space, where it meets the solar wind, a stream of charged particles emitted by the sun. For the most part, the magnetosphere acts as a shield to protect Earth from this high-energy solar activity.

What happens in the convection zone layer of the Sun?

Energy from the radiation zone passes into the convection zone, the outer layer of the sun’s interior. In the convection zone, energy is transferred outward mainly by convection currents. Hot gases in the convection zone rise toward the sun’s atmosphere while cooler gases sink downward.

What layer of the Sun is the chromosphere?

The chromosphere is the second most outer layer of the Sun. Several thousand kilometres thick, it resides above the photosphere and beneath the corona. Due to its low density, it is relatively transparent, resulting in the photosphere being regarded as the visual surface of the Sun.

What is the role of the convection zone?

A region of turbulent plasma between a star’s core and its visible photosphere at the surface, through which energy is transferred by convection. In the convection zone, hot plasma rises, cools as it nears the surface, and falls to be heated and rise again.

What are the photosphere chromosphere and corona?

The Sun – our central star

Beginning from the outside, they are: the corona – the outermost, hot shell of the atmosphere. the chromosphere – a transparent layer between the corona and the photosphere. the photosphere – the visible “surface” of the Sun.

What is the differences between chromosphere and photosphere?

The photosphere is the Sun’s outer shell from which light is radiated. It has a surface temperature of about 6,000K. The chromosphere is above the photosphere. I is a low density layer which is about 2,000km thick.

What is photosphere and chromosphere?

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. The corona extends outwards for more than a solar radius.

Why can the chromosphere and corona only be seen from Earth during an eclipse?

Remember, the sun has multiple outer and inner layers. Its outer layers are the photosphere, corona, chromosphere, and the transition region. … Because of the light emitted from the sun’s photosphere, without help from a coronagraph, the corona is only visible by sight from Earth during a total solar eclipse.

When the chromosphere can be seen during a solar eclipse it appears?

When the chromosphere can be seen during a solar eclipse, it appears: red.

How can you identify the chromosphere during a total solar eclipse?

How can you identify the chromosphere during a total solar eclipse? It’s a reddish glow at the end or beginning of an eclipse.

Why does chromosphere appear red?

The chromosphere appears red because of the large amount of hydrogen present. You can see this red color at the very edge of the Sun during a total solar eclipse.

Is the chromosphere heated by the corona?

In the chromosphere, almost all the mechanical energy flux supplied to the outer solar atmosphere by magneto-convection is converted into heat and radiation, leaving a small amount to power the solar wind and the hot corona: the chromosphere requires over 30 times more energy than the corona and heliosphere combined.

Why is the chromosphere hotter than the photosphere?

In 1942, the Swedish scientist Hannes Alfvén proposed an explanation. He theorized that magnetized waves of plasma could carry huge amounts of energy along the sun’s magnetic field from its interior to the corona. The energy bypasses the photosphere before exploding with heat in the sun’s upper atmosphere.

What is the significance of the Maunder minimum?

The Maunder Minimum, also known as the “prolonged sunspot minimum”, was a period around 1645 to 1715 during which sunspots became exceedingly rare. During a 28-year period (1672–1699) within the minimum, observations revealed fewer than 50 sunspots.

What heats the chromosphere and the corona to a high temperature?

The heating of the corona and chromosphere is believed to be caused by the convection of gas, this convection shakes the magnetic field lines and energy is carried up them into the solar atmosphere where the energy is released as heat.

What are the general trends in temperature and density from the corona to the chromosphere to the photosphere?

What are the general trends in temperature and density from the photosphere to the chromosphere to the corona? The temperature increases and density decreases. What physical property of the sun is responsible for “limb darkening”? The lower photosphere is hotter than the upper photosphere.

How can astronomers detect structure in the chromosphere?

How can astronomers detect structure in the chromosphere? Ans: The structure of the chromosphere is studied primarily using filtergrams. Filtergrams are images of the sun taken through a filter that lets in a very narrow wavelength band of light, such as light emitted by the Hydrogen-alpha transition.
