Document Summary
Environmental geology looks at the interaction between humans and the geological environment. If the hypothesis gets accepted through experimentation it becomes a theory. No: reject hypothesis (new hypothesis: explain the two main hypotheses of the origin of the universe, primeval atom: the universe was crushed down into a small ball (quarks) Explosion of quarks (big bang): formation of proton and elevtron: singularity: non-dimensional spot filled with energy; empty space. E=mc2 (energy can be converted to matter, and other way around) It from 1 sec to 5 minutes after the big bang. The immense heat of the explosion caused the fusion of the quarks (fundemental particles) and formed the protons (1h) and neutrons. Big bang nucleosynthesis- first stars initiated fusion ~1 billion years after the big bang a- fusion of 2h to 4he. Increased heat allowed for the fusion of helium into carbon : 4he+4he-->8be+4he-->12 c. 3-small amount of 16o is also produced by adding 4he to 12c.
