Don't Panic Geocast

Episode 35 - "So often we disconnect these things" Why study geology?

September 18th, 2015

This week we discuss how geoscience can enrich anyone’s life. Join the discussion and then learn about how much cosmic dust falls on us every day!

Why Learn Geology

Spatial thinking/reasoning

  • Thinking in 3D is hard… 4D is harder
  • 3D Mouse


  • We need resources for our modern lifestyle
  • Earth is continuously changing (as pointed out in the article), so preserving it as is should NOT be the goal, but preserving a habitable planet.

Place based knowledge

  • Connects you directly to the land. Everyone has a “place” and by further exploring it through geology it can create a deeper connection.


  • “Any good intro geology course is actually a course in time”
  • Geologic time…it’s really big!
  • Pale Blue Dot Photo
  • Puts things in perspective. Carl Sagan’s Pale Blue Dot commentary does a great job of showing spatial and temporal smallness. It doesn’t make you feel small though, it makes you feel free. Chokes me up every time; Watch it here
