## What do you learn in Geomicrobiology

Geomicrobiology explores how microorganisms interact with geological processes. You'll study how bacteria and other microbes influence rock formation, mineral dissolution, and element cycling. The course covers microbial metabolism in extreme environments, biomineralization, and the role of microbes in shaping Earth's history. You'll also learn about biogeochemical cycles and how microorganisms impact environmental remediation.

## Is Geomicrobiology hard?

Geomicrobiology can be challenging because it combines concepts from geology, microbiology, and chemistry. You'll need to wrap your head around complex interactions between microbes and minerals. The course often involves lab work and field studies, which can be time-consuming. That said, if you're into Earth science or biology, you'll probably find the material fascinating and worth the effort.
