What does a geologist do?

Geologists study the Earth, including its materials, processes, physical structure, and history. They analyze rocks, minerals, and fossils to understand how the planet has changed over time and to predict future geological events. Geologists often work in the field collecting samples, in laboratories conducting tests, and sometimes consult on construction projects, environmental issues, or resource exploration. Their work is vital in identifying natural resources, assessing natural hazards, and helping protect the environment.
