What differences in soil types exist among north carolina's regions?

Answer 1

"The Carolina and Georgia Sandhills region of the Southeast is an elongated area of sandy soil that is located adjacent to regions of varying soil type. The Piedmont area to the northeast has soils that are mainly loam and clay-loam, while a variety of soil types exists in the Coastal Plain to the southeast. It is the differences in these soil types that create differential heating of the surface. Areas with sandy soil will more easily release their moisture to the area, allowing for a higher sensible heat flux than loam or clay-loam soils. This allows more energy to be used for heating the surface rather than evaporating moisture in the soil. Also, the heat capacity for sand is much less than that of clay or loam, so that given the same amount of energy, sandy soil would increase in temperature more than the loam or clay soils."
