Protoplanet Hypothesis | A possible explanation for the formation of the solar system |
Hypothesis | A possible explanation for an observed set of facts |
Free oxygen | Oxygen that is not bonded to other elements |
Photosynthesis | Process by which plants produce food & Oxygen from Carbondioxide, Water & sunlight; respiriation is the opposite of this equation |
Revolve | To orbit something |
Rotate | To spin on an axis |
6 Facts about our Solar System | 1. All planets move around the sun (revolve) in the same direction. 2. The paths, or obits of the planets are all elliptical. 3. Most of the orbits are in nearly the same plane. 4. The sun turns on its axis(rotates) in almost the same plane as the planets and in the same direction that the planets revolve. 5. Most of the planets rotate in the same direction as the sun. 6. Seven of the nine planets have moons. Most of the moons revolve around the planets in the same dirction the planet goes around the sun. |
2 Planets lacking moons | Mercury & Venus |
Planet that rotates on its side (tipped 90degrees) | Uranus |
Planet that rotates backward (retrograde rotation) | Venus |
Approximate age of the Solar System | 4.6 Billion years old |
Simple formula for nuclear fusion | H + H = He + Energy |

Who stated E=mc^2 | Einstein |
1st Law of Thermodynamics (def) | matter can neither be created nor destroyed in only changed from one form to |
2nd Law of Thermodynamics (def) | When energy changes it is converted from a more useful, more concentrated form to a less useful, less concentrated form. |
