Answer:
Here is the answer
Explanation:
1-photosphere
2-Chromosphere
3-corona
4-Sunspots
5-Core
6-convection zone
Ans1-Photosphere - The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that.
Ans2-The chromosphere is a thin layer of the sun's atmosphere that lies just below the corona, and about 3,100 miles (5,000 km) above the photosphere. It is only visible during total solar eclipses or with sophisticated telescopes.
Ans3-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. More detail on the outer layers follows: Photosphere - The photosphere is the deepest layer of the Sun that we can observe directly.
Ans4-Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere. The photosphere has a temperature of 5,800 degrees Kelvin.
Ans5-Core. A star's core is the innermost part. It is the densest and hottest area.
Ans6-A convection zone, convective zone or convective region of a star is a layer which is unstable to convection. Energy is primarily or partially transported by convection in such a region. In a radiation zone, energy is transported by radiation and conduction.
Stellar convection consists of mass movement of plasma within the star which usually forms a circular convection current with the heated plasma ascending and the cooled plasma descending.
The Schwarzschild criterion expresses the conditions under which a region of a star is unstable to convection. A parcel of gas that rises slightly will find itself in an environment of lower pressure than the one it came from. As a result, the parcel will expand and cool. If the rising parcel cools to a lower temperature than its new surroundings, so that it has a higher density than the surrounding gas, then its lack of buoyancy will cause it to sink back to where it came from. However, if the temperature gradient is steep enough (i. e. the temperature changes rapidly with distance from the center of the star), or if the gas has a very high heat capacity (i. e. its temperature changes relatively slowly as it expands) then the rising parcel of gas will remain warmer and less dense than its new surroundings even after expanding and cooling. Its buoyancy will then cause it to continue to rise. The region of the star in which this happens is the convection zone.
I am not sure about answer 6 sorry if I am wrong at that one.....
