Natural laws (uniform process) gravity, chemical processes (happen the same way everywhere: the law of uniformitarianism. Some natural laws and processes that operate in the universe now have always operated in the universe in the past and apply everywhere in the universe: other laws. When things get broken down, it lays flat) i. e. rocks. Other forces are needed to make things not flat. Layers of rock, the stuff on the bottom is the oldest and stuff on the top is the newest (cannot change the order geologically) Fractured things are younger than the older material. Volcano its coming up through other rocks, since its coming up, its younger than other rocks. Geological time scale: 88. 3% precambrian eon rocks earth is made up of. The atmosphere: climate and weather, outer shell of earth, made up of gases, often transparent, essential to life on earth for several reasons. Moves thermal energy from equatorial regions to polar regions.
