An Ocean World The Ocean and atmosphere are a very small portion of the total Earth Age of formation of Earth ~ 4.5 b.y. Big Bang Density Stratification out gassing of the primitive atmosphere and oceans density differentiation (density = gm/cc ) Cosmic coincidences for the existence of water on Earth and in the three states of matter: solid (ice), liquid (water), and gas (water vapor) original material modified by initial heat (lose light elements) vs gravity (retain light elements) position relative to the sun, etc The Nature of Science Tenable Values and the Scientific Method Hypothesis, testing, modification, more testing, theory, more testing, modification, laws Use of in reverse to make predictions Is the scientific method the means to discovering "Pure Truth"?
