Etymology
Origin of geologic
Explanation
Anything that's geologic has something to do with the structure of the Earth and the way it has changed over time. Scientists who study geologic features — including rocks in the earth's crust, volcanoes, sandy beaches, and all the other non-living things that make up our planet — are called geologists. If you're interested in geologic formations like the long, pointy mineral deposits that grow in caves, stalagmites and stalactites, you might consider a geologic career path too! Geologic is from geology and its Greek roots geo, "earth," and -logia, "a science."
