Question

The Sun has six regions or layers. Identify the Sun's layers, beginning with the innermost and moving out. 1. Innermost core 2. 2nd innermost radiative zone 3. 3rd innermost convective zone 4. 4th innermost chromosphere 5. 5th innermost corona 6. Outermost photosphere

Answer 1

Answer: Beginning from the inside and moving towards outside the sun has six layers. Sun is the ultimate source of energy for all the living organisms on earth. The heat and light that comes out of the sun is through the various layers that is present in the sun.

1. Innermost core: It is the region from where the sun gets all the energy. Here hydrogen and helium is present. Due to high pressure of the surrounding layers hydrogen fuses into helium releasing high energy photons.

2. Radiative zone: The high energy photons are now transferred from core to radiative zone. Here the high energy photons are constantly absorbed and re-emitted. It takes millions and billions of years for these high energy particles to come out of this radiative zone.

3. Convective zone: The temperature of this region is quite cooler as compared to that of core and radiative zone. The plasma present in this region makes the magnetic field of the sun.

4. Photosphere: It is the region where sunspots are found. These are called by the magnetic field of sun.

5. Chromosphere: This region is red in color. It contains filaments of gas that rise up from the surface of the sun. This region is cooler than photosphere.

6. Corona: It is the outermost layer of sun and the temperature is much higher here. Many kinds of gaseous emissions takes place make the sun bright and hot.

Answer 2

The sun, like the earth, is made up of numerous layers, each with its own set of properties. The core, the radiative zone, the convective zone, the photosphere, the chromosphere, and the corona are the six layers.

What is sun?

The sun is a star which is present in the center of the solar system. All planetary bodies revolve around the sun.

The sun is made up of six layers:

• The core -The core of the sun stretches 20–25 percent of its total radius from its center. This region produces lots of thermal energy.

• The radiative zone -This layer comes after the core. The temperature of this region decrease from 7 million to 2 million kelvin.

• The convective zone -This layer decrease from 0.6 radii to near surface. The density of plasma in this layer is lower than former layers.

• The photosphere -This is the visible layer of the sun, from here the sun become opaque to visible light.

• The chromosphere -The color of this area is red. It contains gas filaments that rise up from the sun's surface. This part of the planet is cooler than the photosphere.

• The corona -The temperature is substantially higher here because it is the sun's outermost layer. The sun is brilliant and hot due to a variety of gaseous releases.

Thus, these are the six layers of the sun.
