Explanation
If you’re fascinated by rocks and spend hours digging for interesting samples in the backyard, you might be a budding geologist, a scientist who studies all things related to the Earth. A geologist is an expert in the field of geology, the study of what the Earth is made of and how it was formed. The woman on TV explaining the history of an active volcano that’s ready to erupt? She’s probably a geologist who specializes in volcanoes. Geologists can specialize in many different aspects of the field, ranging from earthquakes to soil erosion. What they all have in common is that they’re trying to figure out how the Earth works.
