It was the most interesting thing I'd ever done. So I kept taking geology courses. Dr. Mora is a geochemist. Geochemists use their knowledge of chemical processes in nature to study the way the Earth formed, how it has changed over time, and how it might change in the future. Dr. Claudia Mora discusses geology with a group of girls.
Geologists study different parts of the Earth.
Some study volcanoes or earthquakes. Others study the oceans. Still others consider how life on Earth evolved and has changed over time. Get a good background in math and science. Then, if you change your mind, you'll be ready.
