Anyone who enjoys being outdoors, and wonders about the nature of things would enjoy geology. Geology, especially field work, is a lot of fun if you don't mind a little sweat, a few snakes and scorpions, occasional heat and cold. And geology is not confined to political boundaries. It is a global science. Geologists use the principals of chemistry and physics to study rocks and minerals as well as natural hazards such as earthquakes and volcanoes.
Geologists also use the principals of biology to study paleontology.
It is important to get a firm background in chemistry, physics, biology and math for the understanding of the earth sciences. Field work on Lake Bikal in Siberia, in western and southern Spain, the California deserts, and Rocky Mountains are incredibly interesting. The mix of policy and physical science every day was very exciting. The basis for study and mitigation of natural hazards such as earthquakes and volcanoes rests on the study of geology. Non-renewable resources can only be explored through an understanding of the geology of ore deposits.
