The Nebular Hypothesis Creation of the solar system
How was the solar system Created? • Our universe began as a cloud of dust and gas (Hydrogen and Helium)
Phase 2 The Nebula stared to rotate and collapse toward the center. • Heat generated in the middle by friction caused the formation of the sun
Phase 3 Cooling of the Nebula caused smaller rocky/ metallic objects to form
Phase 4 • Mercury • Venus • Earth • Mars • Repeated collisions of Asteroids formed the four inner planets These Planets are • Dense • Solid • Terrestrial
Phase 5 • Lighter materials such as Gas, Dust, Ice, formed the outer planets • Jupiter • Saturn • Uranus • Neptune These Planets are • Gaseous • Colder • Less dense
