U238 -> th234 + 4he (alpha ejected from neuc) Decay chains, begin decay, products are unstable too, keeps going until you get a stable el (usually lead) New el are created when neut (produced by incoming cosmic ray particles) react with existing el. Immanuel kant 1775]solar system condensed from a rotating nebula. Initial rotation of the cloud accentuated by conservation of angular momentum. Gasses in disk condensed, begin to clump together into planetisimals. Gravitational compaction at center to start nuclear fusion the sun. Planetesimals collide to form larger bodies, sweeping their orbits, resulting in planets. Radiation pressure from young sun blew the light, gaseous compounds away from inner planets (h, he, Asteroids are remains of condensed material never effectively collected into planet, possibly because of.
