Reducing the risk to people of volcanic eruptions is an important job for geoscientists.  In this episode, we talk about four tools geoscientists can use including earthquakes, deformation, gases, and well water temperatures.

This would make a great introduction to students before having them do the Thunder Island volcano simulation activity.

Rivers are so important as they provide water for drinking and agriculture.   They are also important as they move mountains (over time) to the ocean!   In this episode, we talk about the basic morphology of rivers - bedrock and alluvial rivers as well as the concepts of young, mature, and old rivers.  It is a very basic introduction to ways of looking at rivers.

The formation of Banded Iron Formations (BIFs) are so important as a resource of the element iron, but also as they tell us about how our atmosphere evolved some 2,500 million years ago.  In this episode, we talk about the major theory of the formation of BIFs as well as some alternative theories, and what BIF's can tell us about how the evolution of simple blue-green algae changed our Earth for ever!

What are the six groups of natural geological resources that humans have learned to utilize to build our society into the form that we now live within?    Humans have been using water, ores, aggregates, energy, stones, and soil to live on Earth - and understanding them is so important to be able to keep using them in a sustainable way.

This is a great introduction to natural resources.

The Earth's tectonic plates are made up of the lithosphere - that outer hard rock layer of the Earth.  In this episode, we talk about the lithosphere, the underlying asthenosphere, and the moho boundary between the crust and the upper mantle portion of the lithosphere.  And all in under 9 minutes!

This is essential listening for students learning about Plate Tectonics!

We all live on Earth's continental crust - and so it's the part of our planet we are most familiar with.  But do you know what makes this type of crust so special?  In this episode, we talk about the continental crust, what it is made up from, how thick it is, and why it contains the oldest rocks on Earth.

This is essential listening for students learning about Plate Tectonics!
