![]() ![]() If you are interested, talk to your geology instructor for advice. Many of these career options require a college degree and postgraduate work. Additional career pathways are available in the private sector including in mining and natural resource extraction. ![]() Many are employed by universities where they teach and/or do research, and state and federal agencies, including geological surveys, like the California Geological Survey or United State Geological Survey (USGS). Like many other geoscientists, working with other disciplines is common, with a heavy influence from both math and technology. Those who study geologic time can be associated with a variety of disciplines within geology, including sedimentology, paleontology, geomorphology, petrology, structural geology, and many others.

Early geologists (naturalists) were able to piece together a progression of rocks through time to construct the original Geologic Time Scale, and geologists continue to update and make the timescale more accurate ( Figure 14.1). Geologists have used a variety of methods to map major geologic events and their duration to reconstruct Earth’s history during the last 4.54 billion years. For example, if geologic time is relatively short (less than a 100 million years) then catastrophic events would have been required to form the features we see on the surface of Earth whereas vast amounts of geologic time (more than 100 million years) could have produced the slow, steady rate of change we observe around us today.Įxamining geologic time, or deep time, can be challenging for humans, as it is difficult for us to imagine hundreds of millions or billions of years. Different hypotheses about the age of the Earth offer drastically different perspectives of the workings of geologic events that formed and shaped the planet. The amount of time involved in carving a landscape, forming rocks, moving continents is an important scientific question. ![]()
