What is the chromosphere in the Sun?

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. The chromosphere extends for about 2,000 kilometers (1,200 miles) above the visible surface of the Sun.

What is the purpose 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 is the chromosphere called?

The chromosphere (colour sphere), named by the English astronomer Sir Joseph Norman Lockyer in 1868, appears briefly as a bright crescent, red with hydrogen light, during solar eclipses when the body of the Sun is almost obscured by the Moon.

What is chromosphere in chemistry?

Definition: Chromosphere is a reddish and glowing layer of gas above a star's (or Sun's) photosphere. It is actually the transition between corona and the photosphere.

What is the chromosphere made up of?

The chromosphere is mainly made of hydrogen and helium plasma, which is ionized to produce red visible light, as seen during an eclipse.

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.

What is 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.

How hot is the chromosphere?

the chromosphere is the innermost atmospheric layer. It is just above the photosphere. Here the temperature begins to rise again, to about 36,000 degrees F. Above the chromosphere is the transistion layer, where temperatures increase 6000 to over half-a-million degrees.

What is the Sun's corona?

corona, outermost region of the Sun's atmosphere, consisting of plasma (hot ionized gas). It has a temperature of approximately two million kelvins and an extremely low density. The corona continually varies in size and shape as it is affected by the Sun's magnetic field.

Where is the chromosphere of the sun quizlet?

Definition: The photosphere is the visible surface of the sun. Sentence with extra information: The photosphere is the innermost layer of the sun. Definition: The chromosphere is outside of the photosphere and is approximately 2,500 km thick and has a temperature of nearly 30,000 Kelvin.

Where is the chromosphere located?

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).

Why is the chromosphere pink?

The chromosphere represents the dynamic transition between the cool temperature minimum of the outer photosphere and the diffuse million-degree corona above. It derives its name and pink colour from the red Hα line of hydrogen at 6562.8 angstroms (Å); 1 Å = 10⁻¹⁰ metre.

Is the chromosphere hotter than the photosphere?

While the photosphere hovers around 5,800 kelvin, the temperature of the chromosphere varies between 4,500 K and 20,000 K. Even though it's more distant from the center of the Sun, the chromosphere is hotter than the photosphere. ... It has a reddish color, but you can only really see it during a total solar eclipse.

What does photosphere mean in science?

photosphere, visible surface of the Sun, from which is emitted most of the Sun's light that reaches Earth directly. ... Scientists consider the “surface” of the Sun to be the region above which most photons (the quantum carriers of light energy) escape. The photosphere is thus a layer some 400 km (250 miles) thick.

Who discovered the chromosphere?

They were discovered in 1877 by Father Angelo Secchi of the Observatory of Roman Collegium in Rome. They last for about 15 minutes and carry about 100 times the mass density per second as the solar wind.
