Layers of the Sun
![Picture](/uploads/1/3/1/3/13133061/8619226.jpg)
Core: · Source of the Sun’s energy
· Keeps energy output constant
· Filled with compact hydrogen atoms
· Over 4 billion degrees protons and neutrons bounce around creating plasma, nuclear reactions energy
· High temperature and density create fusions.
Radiation Layer:
· High temperatures 14,000,000°C this is where fusion of hydrogen nuclei takes place
· Energy from the core is passed randomly from atom to atom until it reaches the radiation zone, it takes 170,000 years for energy from the core to reach it
· It is cooler than the core, so, some atoms are able to remain intact and absorb energy
Convection:
· The boiling zone
· 2,000,000° kelvin
· Hot gasses bubble up to the surface causing the rising and falling granules
· Hot energy rises and cooling energy sinks to the bottom
· Much faster than radiation
· Takes just over a week for hot material to move through this layer.
Photosphere:
· Apparent surface of sun
· Completely made of gas
· Not a solid
· Gas becomes dense and we can’t see it
· Coolest part of sun 6,000°C
· Gas is thin so atoms can be absorbed and release energy
· Sun spots are dark cooler spots that can be seen on the surface of the sun
· They are cooler then the surrounding gas
· They can last from 1 hour to several months
Chromosphere:
· Red appearance
· 2,000km thick
· Range from 6,000°C-50,000°C
· Hydrogen layer
· Jagged layers that looks like flames
· 32,000km-400,000km flames reach
· Flames last few days/ weeks
Corona:
· Outer layer only seen when sun is blocked e.g solar eclipse
· Very thin layer stretches out into space
· Keeps energy output constant
· Filled with compact hydrogen atoms
· Over 4 billion degrees protons and neutrons bounce around creating plasma, nuclear reactions energy
· High temperature and density create fusions.
