Terrestrial Jovian Other objects pluto Solar system formation $200 $200 $200 $200 $200 $400 $400 $400 $400 $400 $600 $600 $600 $600 $600 $800 $800 $800 $800 $800 $1000 $1000 $1000 $1000 $1000 $200 All terrestrials are denser than jovians Compare Terrestrials densities to Jovian $400 Slowed down about .0015sec/century Is the Earth’s rotation slowing down or speeding up $600 Weak Awhat kind of magnetic fields do terrrestrial planets have $800 Heaavier elements compared to Jovian such as carbon dioxide, nitrogen, and water vapor What are the atmospheres of the terrestrials planets like $1000 Heavier elements, slow rotations, few moons, smaller Describe the terrestrial planets as a group $200 Jupiter, Saturn, Uranus and Neptune What are the Jovian Planets $400 Jovian Which have rings around them, Jovian or Terrestrial? $600 Made of lighter elements (hydrogen and helium), less dense, rings, lots of moons, larger orbits, faster rotations and bigger. How are Jovians different from terrestrial? $800 Near circular orbits, close to the same plane, revolve counter clockwise around the sun and moons revolve counter clockwise. How are Jovians similar terrestrial planets? $1000 A MOON To determine the mass of a planet using Newton’s laws of gravity, the planet must have $200 sun Which body has the greatest gravitational pull on the Earth? $400 Beyond Neptune Where in the solar system does the Kuiper belt lie? $600 In the Asteroid belt between Jupiter and Mars Most asteroid are found $800 SIZE The difference between a meteoroid and an asteroid is the object’s $1000 CERES The largest asteroid and and probably the only one to be a spherical “world” is $200 Plutoids ,icy comet-like bodies The kuiper belt is an outer asteroid belt consisting of what types o solar stem objects? $400 In the Kuiper belt Where does Pluto live? $600 Irregular Which object made scientists rethink Pluto as a planet? $800 Dr. Brown or Neil De grasse Tyson Name one scientist who was to blame for the demotion of Pluto $1000 It has not cleared it’s path What was the reason for Pluto being “Plutoed” $200 Nebular What is the theory that is currently used to describe the formation of the Solar system? $400 Accretion What is the term used when dust and particles accumulate to grow into an object? $600 The early solar nebula flattened into a disk Why do the orbits all lie in the same plane? $800 Shock wave What might have made the original solar nebula contract? $1000 Dust provides the condensation nuclei around which accretion occurs. What is the role of dust in the condensation theory?
