Dry sand is a poor conductor of electricity, and soil and rock conductivity varies widely based on soil type, season, weather, temperature, and moisture content, making the resistance of the earth connection highly variable and dependent on local conditions.

“dry sand is a pretty good insulator. In fact, soil and rock vary widely in how well they conduct electrical current. The resistivity changes with soil type, seasons, weather, temperature, and moisture content.”
