  1. Adam Marth-Earth Science Solar system formation

  2. Energy can neither be created nor destroyed; Only Transformed

  3. Claims the origin of the solar system came from a rotating cloud of interstellar gas (or a nebula) • Believed to be remnants of dead star systems long before the birth of ours • Formed by supernovas Nebular Theory

  4. Cloud of ice and gas contains a mass amount of gravitational potential energy Cloud collapses inward Gravitational Potential converts to kinetic Spinning Flattens the cloud into a disc Disc spins faster as it is pulled in more Center gets REALLY hot and becomes a star; stellar winds from this blow gas and dust Nebular Theory (contInued)

  5. Terrestrial Planets • Mercury, Venus, Earth, and Mars • Comprised of metal and rock • Smaller planets • Higher Temperature • Few or Zero Moons Planets

  6. Gases condense into rocky materials Accretion Became large clumps of rock called planetesimals Planetesimals collide over time Sun melts away ice and gases How did these Planets Form?

  7. Jovian Planets Jupiter, Saturn, Uranus, Neptune Comprised mainly Helium and Hydrogen Massive planets Rings of ice and rock Many Moons Planets

  8. Gas particles condense to icey particles Particles clump Accretion Planetesimals form-they accrete more Massive clouds of gas form around ice Jovian planets form How Did These Planets Form?

  9. Most extra solar planets detected are “Hot Jupiters” • Gas giants closed to planets opposed to small rocky planets • Venus spins in the opposite direction What is Wrong with this theory?
