2. Sun & Solar System
Structure of the Sun:
Core: where nuclear fusion occurs
-this creates the immense heat (15 millionoC)

3. Sun & Solar System
Structure of the Sun:
Core: where nuclear fusion occurs
-this creates the immense heat (15 millionoC)
Radiative Zone: energy radiates through this zone on its way outward
Convective Zone: heat moves outwards by convection while cooler matter moves back towards the core

Structure of the Sun:
Core: where nuclear fusion occurs
-this creates the immense heat (15 millionoC)
Radiative Zone: energy radiates through this
zone on its way outward
Convective Zone: heat moves outwards by
convection while cooler matter moves back towards the core
Photosphere: where light and other forms of
radiation escape (5500oC)
Atmosphere: divides into two layers:
Chromosphere: inner atmosphere (65,000oC)
Corona: outermost layer
-extends millions of kilometres into space

5. Sun & Solar System
Surface of the Sun:
Sunspots: dark spots appearing on the Sun's
surface that are cooler than the area
surrounding them
-caused by disturbance in the Sun's magnetic
field
Solar flares: gases and charged particles
expelled above an active sunspot
Solar prominences: low-energy gas eruptions
from the Sun's surface that extend thousands
of kilometres into space

Sun's Effects on Earth:
Aurora Borealis: a display of shifting colours in
the northern sky caused by solar particles
colliding with matter in the Earth's upper
atmosphere
Aurora Australis: simultaneous display near
the South Pole

Sun's Effects on Earth:
Communication Disruptions: particles ejected
by the sun in solar flares can damage
satellites around Earth
Radiation Hazards: airplane travel can dose a
person with as much radiation as an X-ray
