Please forgive my ignorance as I learn to read an aeronautical chart.
Looking at the legend it appears Class E is the purple gradient circle
and Class C is the solid line around Nashville. How do you interpret
that 36N 87W is in Class E, as it is outside that gradient circle? Is
Class E space "just everywhere" like Class A? If it is, why label it
separately on charts?


Look at the chart legend under "Airport Traffic Service and Airspace
Information". Just beneath the airspace symbology is the statement, "Class
E Airspace exists at 1200' AGL unless otherwise designated as shown above."
