This air shower consists of a cascade of interactions producing more particles that subsequently undergo further interactions. This air shower consists of a cascade of interactions producing more particles that subsequently undergo further interactions.
Thus, the number of particles rapidly increases further down the air shower. Thus, the number of particles rapidly increases further down the air shower.
This happens until the mean energy per particle is sufficiently lowered such that these particles are absorbed by the atmosphere. This happens until the mean energy per particle is sufficiently lowered such that these particles are absorbed by the atmosphere.

Due to the large inertia of the positively charged ions with respect to their light, negatively charged electrons, a negative charge excess is created.
