6. Planet: Earth

7. Solar system

8. Milky way Galaxy located on: Orion Spur

9. Galaxy cluster

10. Super cluster Virgo galaxy cluster

12. The Solar System

13. Nebula Theory (our solar system) The solar system started from the spinning and condensing of a cloud of dust and gas. The greatest matter formed the sun with the remaining becoming the planets.

14. Inner Planets Terrestrial planets –Mercury –Venus –Earth –Mars Formed as small rocky material nearest to the protostar(our sun) cooled.

15. Jovian (outer planets) Jupiter Saturn Uranus Neptune

16. Perihelion- when the planet is closest to the sun Aphelion- when the planets are farthest away Planets orbit in ellipses

17. Sun Features: Core –nuclear fusion occurs Radiative zone- energy moves outward in waves

18. Convection zone- warmed gases rise and cool gases sink Photosphere- the visible surface of light

19. CHROMOSPHERE Above the photosphere Reddish in color contains spikes of gas called spicules that rise through it

23. Sunspots: are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. –They are caused by intense magnetic activity, which inhibits convection

24. CORONA Outermost atmosphere of the sun Seen only during a total solar eclipse Very hot but thin

26. Sunspots: are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. –They are caused by intense magnetic activity, which inhibits convection

27. Solar Winds Corona prevents most particles from exiting the sun. However, some Ions/ particles escape as Solar Winds. Causes Auroras (northern lights).

28. SOLAR FLARES- Large Eruptions of Gas Increases Auroras

29. Prominences: large, bright, gaseous feature extending outward from the Sun's surface, often in a loop shape.

30. A coronal mass ejection (CME): is a massive burst of solar wind and magnetic fields rising above the solar corona or being released into space. * Can only see corona during an eclipse

31. An aurora is a natural light display in the sky –Auroras are caused by charged particles, mainly electrons and protons

34. Increased solar flares activity can interrupt communication systems on earth

35. CORONA SOLAR FLARES SUN SPOTS PROMINENCE SPICULES CHROMOSPHERE PHOTOSPHERE CONVECTION ZONE RADIATIVE ZONE CORE

36. Asteroids are small metallic rocks that orbit the sun between Mars and Jupiter

37. METEORS A meteoroid from space that burns up in our atmosphere

39. Meteorites Chunks of rock that have hit the earth’s surface

40. DIRTY SNOWBALL Composed of dust, gas, and ice Has a tail as it approaches the sun COMETS

44. The End
