Document Summary
The scientific method: compile observations, form hypothesis (provisional theory), test hypothesis. If hypothesis survives repeated testing, form a theory. Theory: a well-substantiated explanation that is repeatedly tested and confirmed through observation and experimentation. Law: a theory/set of theories that is observed to always happen. The findings of scientific research should be open to scrutiny of the scientific community (continual reexamination). Earth system science: the interdisciplinary study of the treatment of the earth as a complex integrated system (many interacting parts) The planet is a layered structure with least dense material on outside and most dense in the core. Atmosphere: the envelope of gasses surrounding the earth. Biosphere: the area of the earth occupied by living organisms (surface, atmosphere, hydrosphere) Crust: about 30 km of rigid material (oceanic about 10km) Lithosphere: crust and uppermost part of the mantle. Mantle: hot layer of semi solid rock, 2900 km thick.
