Hydrology is the study of Earth's water, how it moves, and distributes. Here, we speak with Zachary Heck, a hydrologic technician for the USGS, to learn more.

Hydrogeology is the study of Earth's water within deep, underground cavern systems called aquifers. We talk to Deon Knights, an Earth scientist who studies deltas and estuaries to find out more.

Neotectonics, a subdicipline of tectonics, is the study of how plate motion deforms and affects the Earth's crust in recent geological time. We sit down with Jon Lewis, a geology professor from the Indiana University of Pennslyvania, to find out more.

Paleontology is the study of fossilized remains of past plants and animals. Today, we speak with Blaire Voss, a paleontology graduate student from West Virginia University, to see why he digs fossils so much.

Petroleum geology is the exploration and harvesting of natural gas trapped within our Earth. We interviewed Gretchen Gillis, geologist and current American Association of Petroleum Geologists president, to learn more about this careerpath.
