It can also be influenced by local climate conditions, as shown in the next chart showing
soil resistivity by temperature.

The next largest set of factors that influence resistivity are electrolytic, a topic that will be
covered in greater detail in the next chapter.
Summary
Had you ever imagined that there would be a relationship between soil and its composition
with regards to electricity? Who would have known that soils are naturally electric in that
they hold and transport charge? The fact of the matter is that most life is electrical, for
