Document Summary
The earth an all parts of our solar system originated from nebular cloud of gas and dust in milky. Solar nebular model: types of planets: terrestrial (the earth and other planets near the sun). Jovian (planets away from the sun (also known as gas giants)). Earth is formed by deposit of rocky nodules. Nodules are formed by condensation in nebular and solar nebular. The inner part of the solar nebular is composed by: fe, mg, al, ni, ca, na, k. Earth"s reorganization: melting of deposited material and transformation into layered structure: core (dense liquids sink into core. The core is mostly constituted of iron in solid in liquid state, it constitutes about 15% of the volume of earth and 32% of the mass of the earth. The iron is inherited from the nebular cloud. It was produced as a waste product of stellar fusion (present in nebular cloud; origin in star interior; spread around by nova explosions).
