An international geologist travels the globe to study, analyze, and research how land gets created and what affects that had on the past, present, and future. Your duties involve the exploration of the earth. You travel abroad to collect rock samples, collaborate with scientists, run tests on the soil to understand plant and animal life, assess minerals and land formations for mining and oil drilling, and create reports on your findings. An international geologist may handle responsibilities for a company with locations in different countries or perform field work internationally and return to a home base for lab work.
