  1. The Solar System

  2. List the 9 planets in our solar system. • Mercury • Venus • Earth • Mars • Jupiter • Saturn • Uranus • Neptune • Pluto (dwarf planet)

  3. 2. List each planet and the main facts about each.

  4. Mercury • 2nd smallest planet • no atmosphere • craters • smooth terrain • deep slopes • 1 rotation = 59 days • Temp: 800 F to -279 F

  5. Venus • Orbits sun every 255 days • Thick clouds • Volcanic activity • Tectonic activity • 80% plains covered by volcanic flows • Temp: 887 F • Atmosphere is 97% CO2

  6. Earth

  7. Mars • The red planet • White polar caps • Large dust storms • Hurricane force winds • Large volcanoes • Large canyons • Temp: - 94 F to – 148 F

  8. Jupiter • largest planet • 1 rotation = 10 hours • great red spot – a cyclonic storm • hydrogen-helium atmosphere • winds cause light and dark bands • immense gravity • gigantic ocean of liquid hydrogen • 28 moons

  9. Saturn • 29.46 years to make one revolution around the sun • Rings made of ice and rock particles • Winds up to 637.5 mph • Large cyclonic storms • 31 moons

  10. Uranus • Rotates on its side • Has rings • Takes 84.01 years to make one revolution around the sun

  11. Neptune • Winds up to 625 mph • Great dark spot – a large rotating storm • 13 moons

  12. Pluto • 248 years to orbit the sun • classified as a dwarf planet • Average temp: 346 F • Dirty ice ball

  13. List the terrestrial planets. • Mercury • Venus • Earth • Mars

  14. 4. What does the term, “terrestrial” mean? Earth-like

  15. 5. List the jovian planets. Jupiter Saturn Uranus Neptune

  16. 6. What does the term, “jovian” mean? Jupiter-like

  17. 7. What are the terrestrial planets made of? Rocky and metallic substances

  18. 8. What are the jovian planets made of? Gases – hydrogen and helium Ice

  19. 9. Nebula Cloud of dust and gas in space

  20. 10. What is the nebular theory? The sun and planets formed from a rotating disk of dust and gases

  21. Nebular Theory

  22. 11. Planetesimals Small, irregular shaped bodies resulting from colliding bits of matter.

  23. Planetesimals

  24. 12. How did the distance from the sun affect the creation of planets? • Planets closer to the sun formed from materials with higher melting points – metals and silicate minerals. • Planets further from the sun formed with solid materials and ices.

  25. 13. Asteroid Small rocky bodies

  26. 14. Comet Pieces of rocky and metallic materials

  27. 15. Coma The glowing head on a comet

  28. 16. Meteoroid A small solid particle traveling through space.

  29. 17. When is a meteoroid called a shooting star? When it enters the earth’s atmosphere.

  30. 18. Meteor A meteoroid that does not enter the earth’s atmosphere.

  31. 19. Meteorite A meteoroid that reaches the earth’s surface.
