Study Notes

Introduction to Geology

  • Geology studies Earth (and other space bodies), its composition, and its processes
  • Explains similar processes on other extraterrestrial bodies
  • Deals with small and large scales, like using maps to find location

Complexity of Replicating Natural Phenomena

  • Scientists use similar examples to simplify natural events
  • Replicating natural events to understand scientific knowledge

Branches of Geology

  • Physical Geology: Examines rocks, minerals, and the processes beneath and on Earth's surface.
  • Historical Geology: Studies Earth's evolution and origin throughout time

Physical Geology - Subdivisions

  • Mineralogy: Studying minerals, the building blocks of rocks (macro and micro)
  • Petrology: Studying rocks, a key focus of geologists
  • Volcanology: Studying volcanoes
  • Structural Geology: Studying Earth's structures, like faults and folds

Issue of Scale

  • Distinction between small-scale and large-scale geological phenomena is important
  • Understanding scale is crucial for civil engineers to map areas successfully

Geology as a Discipline

  • Encompasses a wide range of processes and bodies, including extraterrestrial bodies
