Geology doesn’t end here on Earth, it’s just that most of us are stuck here and can’t look elsewhere. Seriously, how many of us have longed to go rock hunting on another planet but lack the transportation to do so? In this episode, we will meet someone who has found a way around this dilemma. Dr. Elizabeth Rampe, a geologist who is deputy principal investigator on the CheMIn instrument on NASA’s Mars Curiosity Rover joins us to talk about the fascinating world of Martian geology.

Mt. St. Helens is a name that looms large in the mind of any geologist or the mind of anyone who was alive in the USA in 1980. The 1980 eruption of Mt. St. Helens was one of the greatest natural disasters ever to hit the United States of America. The sobering part of it is that it will happen again. This podcast examines the lead up to the 1980 eruption from the point of view of the geologists who met and dealt with the event.

Most geologists are familiar with the Younger Dryas, that somewhat enigmatic period about 12,500 years ago when the northern hemisphere, warming as it came out of the Wisconsin Glaciation, suddenly cooled for a few centuries. As it turns out, this was part of a series of events known as Heinrich Events. Join us for an interview with Dr. Elliott Arnold of West Chester University for a lively interview on Heinrich Events.

We don’t normally think about the relationship between the core of the Earth and the ability of the planet to support life. But it turns out that complex life on Earth would be impossible without a spinning iron-rich core producing the magnetosphere that shields us from the deadly solar wind. Let’s take a look upward and downward and examine the center of the Earth as well as its far-flung outer boundary.
