The sun is made up of six layers: core, radiative zone,
What are the 6 layers of the Sun and their descriptions?
The outer layers are the Corona, the Transition Region, the Chromosphere, and the Photosphere, while the inner layers are the Core, the Radiative Zone, and the Convection Zone.
What are the 7 layers of the Sun?
It is composed of seven layers: three inner layers and four outer layers. The inner layers are the core, the radiative zone and the convection zone, while the outer layers are the photosphere, the chromosphere, the transition region and the corona.
Does the Sun have 6 or 7 layers?
The main part of the Sun has three layers: the core, radiative zone, and convection zone. The Sun’s atmosphere also has three layers: the photosphere, the chromosphere, and the corona. Nuclear fusion of hydrogen in the core of the Sun produces tremendous amounts of energy that radiate out from the Sun.

What are parts of the Sun?
There are three main parts to the Sun’s interior: the core, the radiative zone, and the convective zone. The core is at the center. It the hottest region, where the nuclear fusion reactions that power the Sun occur. Moving outward, next comes the radiative (or radiation) zone.
Does the Sun have a corona?
The corona is the outer atmosphere of the Sun. It extends many thousands of kilometers (miles) above the visible “surface” of the Sun, gradually transforming into the solar wind that flows outward through our solar system. The material in the corona is an extremely hot but very tenuous plasma.
What is the corona of the Sun?
The corona is the outermost layer of the sun’s atmosphere where strong magnetic fields bind plasma and prevent turbulent solar winds from escape. The Alfvén point is when solar winds exceed a critical speed and can break free of the corona and the sun’s magnetic fields.
What is the middle layer of the Sun?
Explanation: Chromosphere literally means sphere of color. It is the middle layer and around 2,000km deep. It is just above the photosphere, the first layer of the sun’s atmosphere.
What are the 10 layers of the Sun?
The inner layers are the Core, Radiative Zone and Convection Zone. The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona. IRIS will focus its investigation on the Chromosphere and Transition Region.
What does the chromosphere look like?
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 is the fourth layer of the Sun?
The fourth layer is a zone of boiling, bubbling plasma that transfers energy outward through a process called convection.
What is the coolest layer?
The coolest layer of the earth is the crust. The mantle is hot enough to melt rocks, and the cores are even hotter.
What is the coolest layer of the Sun?
The photosphere, which is outside the core, is the coolest layer. This is as expected, because normally heat passes outwardly from hot to cold. However, the Sun’s outermost atmospheric layer is much hotter than its surface layer!
What are the dark patches on the Sun called?
Sunspots are dark, planet-sized regions that appear on the “surface” of the Sun. Sunspots are “dark” because they are cooler than their surroundings.
What is the third layer of the Sun?
The third layer of the sun’s atmosphere is the corona. Like the chromosphere, the sun’s corona can only be seen during a total solar eclipse (or with NASA’s Solar Dynamics Observatory). It appears as white streamers or plumes of ionized gas that flow outward into space.
What is the name of the core of the sun?
Radiative Zone: The radiative zone of the Sun starts at the edge of the core of the Sun (0.2 solar radii), and extends up to about 0.7 radii. Within the radiative zone, the solar material is hot and dense enough that thermal radiation transfers the heat of the core outward through the Sun.
Which two elements make up the Sun?
Despite the controversy, everyone agrees on the basics: The sun consists mainly of hydrogen and helium, the two lightest elements. It generates energy at its center through nuclear reactions that convert hydrogen into helium.
How many Earths can fit in the Sun?
If you divide the volume of the sun by the volume of the Earth, you get that roughly 1.3 million Earths can fit inside the sun.
Why corona is so hot?
About 80 years ago, scientists found that the temperature of the solar corona is actually much hotter than the surface, at a few million degrees celsius. … The high temperatures of the corona cause it to expand into space as a continuous outflow of plasma called the solar wind.
What does the word chromosphere mean?
Definition of chromosphere
: the region of the atmosphere of a star (such as the sun) between the star’s photosphere and its corona.
What is eclipse of the Sun?
A solar eclipse occurs when the Moon moves between the Sun and Earth, casting its shadow on a part of Earth’s surface. If the eclipse is total, the light from the bright disk of the Sun is completely blocked, and the solar atmosphere (the corona) comes into view.
What causes a lunar eclipse?
During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. … A total lunar eclipse occurs when the Moon and Sun are on opposite sides of Earth. A partial lunar eclipse happens when only part of Earth’s shadow covers the Moon.
What is the thickest layer of the Sun?
The RADIATIVE ZONE is the thickest layer of the sun.
What layer are you looking at an image of the Sun?
What we see as the “surface” of the sun is the photosphere .
What layer of the Sun is the largest?
The core of the Sun is encircled by two other inner layers: the radiative zone and the convection zone. Q: What is the largest part of the Sun? The radiative zone is the largest part of the Sun. It extends from about 25% to 70% of the Sun’s radius.
What is the outer part of Sun?
The corona (Figure below) is the outermost part of the Sun’s atmosphere. It is the Sun’s halo, or “crown.” With a temperature of 1 to 3 million K, the corona is much hotter than the photosphere. The corona extends millions of kilometers into space.
Why does the Sun look hairy?
Our star is a marvelous orb of seething hot gas. It periodically grows sunspots, “cooler” regions where the magnetic field has become tangled and knotted. Tendrils of plasma called prominences unfurl from the solar limb into space, sometimes making the Sun look like a hairy ball when viewed through a telescope.
What color is the corona of the Sun?
The glowing white corona can then be seen surrounding the eclipsed Sun. Caution! Remember to never look directly at the Sun, even during an eclipse.
What is the study of the Sun called?
The science of studying the Sun and its influence throughout the solar system is called heliophysics. The Sun is the largest object in our solar system. Its diameter is about 865,000 miles (1.4 million kilometers).
How thick is the corona of the Sun?
Core | Radius of 150,000 km | 10,000,000 K |
---|---|---|
Convective Zone | 200,000 km thick | 500,000 K |
Photosphere | 500 km thick | 5800 K |
Chromosphere | 10,000 km thick | 4,000 to 400,000 K |
Corona | 5,000,000 km thick | 1,000,000 K |
What is the chromosphere of the Sun?
chromosphere, lowest layer of the Sun’s atmosphere, several thousand kilometres thick, located above the bright photosphere and below the extremely tenuous corona.

What is the hottest layer?
The inner core is the hottest layer, above 9000 Fahrenheit and it is 1250 km thick! Crust: The Earth’s thinnest layer!
What is the thickest layer?
Pressure and temperature increase with depth beneath the surface. The core is the thickest layer of the Earth, and the crust is relatively thin, compared to the other layers.
What is the thinnest layer?
*Inner core
It is the thinnest layer of the Earth. *The crust is 5-35km thick beneath the land and 1-8km thick beneath the oceans.
What is hotter than the Sun?
In terms of temperature, which of the following is hottest? And the answer: lightning. According to NASA, lightning is four times hotter than the surface of the sun. The air around a stroke of lightning can peak at 50,000 degrees Fahrenheit, while the surface of the sun is around 11,000 degrees.
Does the Sun have a solid core?
The Sun does not have a solid surface or continents like Earth, nor does it have a solid core (Figure 1). However, it does have a lot of structure and can be discussed as a series of layers, not unlike an onion.
How did the Sun get its name?
The word sun comes from the Old English word sunne, which itself comes from the older Proto-Germanic language’s word sunnōn. In ancient times the Sun was widely seen as a god, and the name for Sun was the name of that god. Ancient Greeks called the Sun Helios, and this word is still used to describe the Sun today.
