A wonderful, clear, thorough PowerPoint presentation that provides definitions of Porosity, Permeability, and Capillarity or Capillary Action through different particle sizes. This can serve as a presentation for a lecture, or can be printed as a printable handout for students as a reference. There are several questions at the end of the presentation that serve as a checkpoint to see if the material was understood. The questions are old NYS Regents exam questions from Earth Science exams. Animations within this presentation include highlighting areas of charts, and motion arrows that show the speed and direction of water flow through particles of different sizes.
