Structure Process and Time
Adverbs - How, what when where
Spatial Dimension & Scale
Rough geometric shapes = fractals
Vs.
Geometric shapes-classical Euclidean geometry
Earth rotation – spheroid vs. ellipsoid
Based on - density
Time = when = episodic – vs. long term
spontaneous-slow
Geoid vs. ellipsoid & best fit of base level
