3. BASIC INFORMATIONS
• The sun is a glowing gasious sphere
• about 500 crore years have passed since it started
glowing in this state
• matter exist in the plasma state in the sun

5. THE STRUCTURE OF THE SUN
1.The core
2.Radiative zone
3.Convection zone
4.Photosphere
5.Chromosphere
6.Corona
6. • The core of the sun is at atemperature of 1½ crore kelvin
and has enormous pressure
7. 2: RADIATIVE ZONE
• The energy produced at the core in the form of gamma
rays comes out through the radirative zone after
absorptionandre emission several times
8. 3:CONVCTIVE ZONE
• The convection zone outside the radiative zone recieves
the energy from radiative zone and transpher it in to
photosphere through convection process
9. OUTER LAYERS
• From
energy comes out as
photosphere
• The thin region
and
the vast outer region
are
considerd as the
athmosphere of the sun
11. • The sunspots are
seen as a black spots
on the surface of the
sun and arerelatively
low temperature
regions
• sun spots are also
the source of strong
magnetic field
12. • From the surface
of the sun ,a large
flow of nuclei of
hydrogen and
helium occures
continuously and
this is called solar
wind
13. • Huge flames rise
up and fall back in
the form of an arch
on the surface of
the sun whichis
known as solar
prominence
15. • Energy is produced in the sun due to nuclear fusion
• Four hydrogen nuclei combine together to form a
helium nuclei and in this process,a large amount of
energy is released
