Our Beautiful Sun

Chapter 3.2 – the sun: our very own star7th science


The structure of our sun

  • Corona: The Sun’s Outer Atmosphere

    Chromosphere: Thin region below the corona only 30,000 km thick.

  • Photosphere: Visible part of the Sun that we can see from Earth.

  • Convective Zone: Region about 200,000 km thick where gases circulate.

  • Radiative Zone: Very dense region about 300,000 km thick – WOW, THAT’S THICK!

  • Core: At the center of the Sun where the Sun’s energy is produced.

The structure of our sun:

Energy production in our sun

At first, some thought that burning fuel was the source of the sun’s energy.

Others thought the sun was shrinking and that’s where our solar energy came from.

Who was right?

Energy production in our sun:


Nuclear fusion

Sorry to say that “Burning or Shrinking” was not the right theory. 

The ANSWER: NUCLEAR FUSION

What is Nuclear Fusion: Hydrogen and Hydrogen fuse together to form Helium and WALA – ENERGY IS PRODUCED!

HYDROGEN – HYDROGEN = HELIUM

NUCLEAR FUSION


Solar activity

Sunspots: cooler, darker spots of the photosphere of our Sun.

Solar Flares: Areas of extremely high temperature that when enough energy builds up they VENT into the atmosphere.

Similar to a Volcano building up with gases and then EXPLODES.

A GIGANTIC ERUPTION ON THE SUN!
