Between a Rock and a Hard Place:
Squishing Rocks to Study the Earth's Interior

Assistant Professor of Earth and Planetary Sciences

Moderated by: Cynthia Wichelman, M.D.

Philip A. Skemer, Ph.D.

In everyday experience, rocks may seem hard, brittle and inflexible, but deep in the Earth's interior, elevated temperature and pressure transform rigid rocks into soft, viscous blobs. These flowing rocks give rise to plate tectonics and ultimately most of the geology observed at the Earth's surface. Direct observation of planetary interiors is essentially impossible, so how do we know what's going on down there? We will discuss how rocks can be deformed in the lab and how these experiments provide new insights into the structure and evolution of the Earth and other planets.

Science On Tap highlighted on St. Louis Public Radio and Voice of America!

Science On Tap is a place where, for the price of a beverage, anyone can come to explore the latest ideas in science and technology. Meetings take place outside a traditional academic context, at the Kirkwood Station Restaurant & Brewing Co.

Meetings are held on the last Wednesday of the month during the academic year, usually from 7:00 - 8:30 PM. The standard format is as follows: about 45 minutes of presentation, followed by discussion until 8:30 PM.
