Friday Science Motivation:
All terrestrial life on Earth depends on a microbial community that lives in bedrock, eats granite and turns it into soil.
While plant roots & water can *crack* bedrock, only these microbial specialists can fully decompose it into released minerals.

Some iron-reducing bacteria have proteins on their surface that can directly STRIP ELECTRONS from iron-containing minerals, using those electrons to fuel their metabolic systems.
Along the way, they oxidize the surface of the rock into weakened mineral structures that decay more rapidly.
