Document Summary

The science of geology: rise in population led to move geology and geological engineering, need to asses hazards and mitigate where people live, more geology due to need for natural resources (mining) Water, soil, metallic and non-metallic minerals, and energy: need more resources for the rising amount of people. Earths landscapes were shaped primarily by catastrophes. Led to geologic time scales, how old the earth is from looking at catastrophes. The physical, chemical, and biologic laws that operate today have operated throughout the geologic past. Volcanoes erupting today also erupting up to 3. 7ga. Processes going on in and on the earth. The geologic time scale: magnitude of geologic time involves millions and billions of years. A view of earth: earths 4 spheres. Thin solid crust around: formation of earth"s layered structure, uniformitarianism. Molten rock rose to produce a primitive crust. Chemical segregation made the three basic divisions: formation of moon.
