Sculptors of Earth's Surface | Weathering and Mass Wasting | Week 9 Fall 2020
The objective of today’s episode is to examine how weathering and erosion connect to the human relationship with the environment. Too often, we take for granted the breakdown and movement of Earthly resources. In our discussion, we travel from Heart Mountain, Wyoming, to the North Pacific Garbage Gyre, to Florence, Italy, to Kansas City, Missouri, and finally to Budapest, Hungary.
Debunking Flat Earth Theory, Earthquake Prediction, and Other Myths | Fall 2020
For this week’s podcast, we shall explore some of the misconceptions people have about the Earth’s structure, earthquakes, and volcanoes. Many of the topics discussed here arise from a new book called, Weird Earth: Debunking Strange Ideas About Our Planet, by Donald R. Prothero. Prothero notes that holding bizarre ideas about the world does not necessarily correlate with level of intelligence. In fact, bright people can develop very elaborate, though highly erroneous, rationalizations of their preexisting beliefs.
Timefulness, Geologic Violence, and the Anthropocene | Fall 2020 Week 7
This podcast we will go over the relationship between landscape interpretation and field work, examine why timefulness matters in today’s world, identify how geologists determined Earth’s history, discover the ways in which plates on Earth’s crust interact with one another, and discuss the Anthropocene (Age of Humans).
Seeking Clarity about Climate Change through the Muck of Social Media | Fall 2020 Week 5
In this podcast, we talk about the relationship between climate change and public perception. In the context of climate change, we will be introduced to methods of seeing the signal through the noise of information at our fingertips. We will also explore some ways to generate constructive conversations about climate change.
Episode 3 | Rain Belts, Traditional Ecological Knowledge, and Severe Weather | Fall 2020 Week 4
Today, we are going to talk about severe weather. All of our discussion about atmospheric energy, motion, and moisture has led us to explore the mechanics of extreme weather events—thunderstorms, tornados, hurricanes, droughts, and so on. What will hopefully become clear for you is that learning about severe weather entails learning about the people who experience it, just as much as how storms function.
Episode 2 | Circling the Globe, High/Low Pressure, and Monsoons | Week 3 Fall 2020
Today, we are going to talk about how pressure causes air to move through the atmosphere, how air behaves differently depending on where you’re at, and how the relationship between motion and moisture in the atmosphere interrelate to generate changes in the environment. We will end by identifying the 15th anniversary of Hurricane Katrina and why this event is important to physical geographers.
