Specifically, they are the "lithosphere" land, "hydrosphere" water, "biosphere" living things, and "atmosphere" air. hope this helped </span>
<em>Fractional distillation leads to a better separation than simple distillation because the glass beads in the fractionating column provide "theoretical plates" on which the vapors can condense and then re-evaporate, and re-condense, essentially distilling the compound many times over.</em>
