Explanation:
Depolarization occurs by the opening of K+ voltage gated channels that cause K+ to leave the cell down a chemical gradient. This makes the inside of the cell less positive until there's reversal of polarity and eventually the resting potential is generated at -70 mV.
This is helped by ATP dependent Na+-K+ pumps.

The primary reason that fossil fuels are harmful to the environment is that their use produces large amounts of greenhouse gasses. These gasses cause heat to build up in the atmosphere and raise the average temperature of the planet. Fossil fuels also pollute the air when they're burned and may cause environmental damage when they're mined
When the soil is dry, it wouldn't be easy to make a footprint so the soil must be moist. Later, the print would harden and that preserves the footprint.
Overall: soil is moist.
