The chromosphere is mainly made of hydrogen and helium plasma, which is ionized to produce red visible light, as seen during an eclipse.
Moreover, can chromosphere be seen?
The chromosphere sits just above the photosphere and below the solar transition region. This makes the chromosphere normally invisible and it can be seen only during a total eclipse, where its reddish color is revealed.
Likewise, where is the chromosphere? 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.
Similarly, it is asked, what are the 3 layers of the sun?
The main part of the Sun has three layers: the core, the radiative zone, and the convection zone. The Sun’s atmosphere also has three layers: the photosphere, the chromosphere, and the corona.
What occurs in the 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). The chromosphere is the site of activity as well.

Why is the corona so hot?
These volcano-ish vortices in Sun’s atmosphere may be from twisted mag. Five different wavelengths of light reveal a vortex of gas in the Sun’s atmosphere. This swirling gas may be the result of intense magnetic fields and may explain why the Sun’s corona is so hot.
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.
How hot is the chromosphere?
The temperature in the chromosphere varies between about 4000 K at the bottom (the so-called temperature minimum) and 8000 K at the top (6700 and 14,000 degrees F, 3700 and 7700 degrees C), so in this layer (and higher layers) it actually gets hotter if you go further away from the Sun, unlike in the lower layers,
Does Earth have a Corona?
The corona is usually hidden by the bright light of the Sun’s surface. That makes it difficult to see without using special instruments. However, the corona can be seen during a total solar eclipse. During a total solar eclipse, the moon passes between Earth and the Sun.
How hot is the sun’s corona?
few million degrees
Does the sun rotate?
On average, the sun rotates on its axis once every 27 days. However, its equator spins the fastest and takes about 24 days to rotate, while the poles take more than 30 days. The inner parts of the sun also spin faster than the outer layers, according to NASA.
What is the sun made of?
The Sun is a huge, glowing sphere of hot gas. Most of this gas is hydrogen (about 70%) and helium (about 28%). Carbon, nitrogen and oxygen make up 1.5% and the other 0.5% is made up of small amounts of many other elements such as neon, iron, silicon, magnesium and sulfur.
What is the structure of the earth?
The internal structure of the Earth is layered in spherical shells: an outer silicate solid crust, a highly viscous asthenosphere and mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core.
What part of the sun do we see?
There are 3 main layers of the Sun that we can see. They are the photosphere, the chromosphere and the corona. Together they make up the “atmosphere” of the Sun. The part of the Sun that glows (and that we see with the naked eye) is called the photosphere.
What color is the sun’s core?
It is a common misconception that the Sun is yellow, or orange or even red. However, the Sun is essentially all colors mixed together, which appear to our eyes as white. This is easy to see in pictures taken from space. Rainbows are light from the Sun, separated into its colors.
How does the sun get its energy?
Like most stars, the sun is made up mostly of hydrogen and helium atoms in a plasma state. The sun generates energy from a process called nuclear fusion. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.
Why is the corona hotter than the sun?
The Sun’s corona is much hotter (by a factor from 150 to 450) than the visible surface of the Sun: the photosphere’s average temperature is 5800kelvin compared to the corona’s one to three million kelvin. The corona is 10−12 times as dense as the photosphere, and so produces about one-millionth as much visible light.
How are solar winds formed?
The fast solar wind originates from coronal holes, which are funnel-like regions of open field lines in the Sun’s magnetic field. Such open lines are particularly prevalent around the Sun’s magnetic poles. The plasma source is small magnetic fields created by convection cells in the solar atmosphere.
How many Earths can fit in the sun?
The Sun is 864,400 miles (1,391,000 kilometers) across. This is about 109 times the diameter of Earth. The Sun weighs about 333,000 times as much as Earth. It is so large that about 1,300,000 planet Earths can fit inside of it.
