Sun
- 1. Powerpoint Templates Page 1 Sun Leonardo, Armia P. E-28
- 2. Powerpoint Templates Page 2 • The Sun is a STAR found at the center of the Solar System. What is SUN?
- 4. Powerpoint Templates Page 4 Made up of 74% 24% 4%
- 5. Powerpoint Templates Page 5 hydrogen nuclei + helium = Nuclear Fusion
- 6. Powerpoint Templates Page 6 • Perfectly spherical • Consist of hot plasma
- 7. Powerpoint Templates Page 7 • At around 1,392,000 kilometers (865,000 miles) wide, • the Sun’s diameter is about 110 times wider than Earth’s Add. Info: – the sun’s radius 696,000km – the Earth’s radius is 6, 376km 689,624km
- 8. Powerpoint Templates Page 8 The sun is 150 million km (93 million miles) away from the Earth.
- 9. Powerpoint Templates Page 9 • The sun’s average surface temperature is 5700 Degree Celsius. • the Earth’s average temperature is 20 Degree Celsius.
- 10. Powerpoint Templates Page 10 • The Sun’s core is around 13,600,000 degrees Celsius!
- 11. Powerpoint Templates Page 11 How old is the sun? 4.5 billion years
- 12. Powerpoint Templates Page 12 • The sun changes. • They increase and decrease on a regular cycle of about 10.8 years.
- 13. Powerpoint Templates Page 13 Remember! The Earth orbits is around the sun
- 14. Powerpoint Templates Page 14 • A solar eclipse occurs when the Moon is between the Sun and the Earth.
- 16. Powerpoint Templates Page 16 Where does the sun came from? “GOD” the creator of the universe and all good things.
- 17. Powerpoint Templates Page 17 Why do we need to study about the Sun? • extremely important for life on Earth • The sun provides us with energy, which brings life on our planet
- 18. Powerpoint Templates Page 18 • Without the sun life on Earth would not exist. It would be so cold that no living thing would be able to survive and our planet would be completely frozen.
- 19. Powerpoint Templates Page 19 • Because of the Sun’s huge influence on Earth, many early cultures saw the Sun as a deity or god.
- 20. Powerpoint Templates Page 20 Earth and Sun’s layers
- 21. Powerpoint Templates Page 21 PARTS OF THE SUN Core Radiative Zone Convective Zone Photosphere Chromosphere Corona
- 22. Powerpoint Templates Page 22 Core • Innermost 10% of the Sun’s mass. • It is where the energy from nuclear fusion is generated.
- 23. Powerpoint Templates Page 23 Radiative Zone • Where energy is transported from superhot interior to the colder outer layers by photons. • This also include the core. • Includes the inner approximately 85% of the Sun’s radius.
- 24. Powerpoint Templates Page 24 Convective Zone • Energy in the outer 15% of the sun’s radius is transported by the bulk motion of gas in a process called convection.
- 25. Powerpoint Templates Page 25 Photosphere • The Sun’s visible surface. • The bubbling motion of the convection layers makes the granular patterns we see on the photosphere.
- 26. Powerpoint Templates Page 26 Chromosphere • With huge solar flares and loops of hot gasses shooting up thousand of miles.
- 27. Powerpoint Templates Page 27 Corona • Can only be seen during total solar eclipse.
- 28. Powerpoint Templates Page 28 Other features • Sun spot – dark spots of the sun’s surface • Solar flare – outburst of burning gas
- 29. Powerpoint Templates Page 29 Life expectancy of the Sun
- 33. Powerpoint Templates Page 33 The end. Thank You!
