Here, I build off our discussion of sand to discuss some applications of "aggregate", why it's mined in and near urban centers, and its broad use in drilling wells.
Here, I talk about porosity and permeability as applied to groundwater and introduce some of the contentious issues around water resources, particularly in water-stressed (arid) environments.
Here, I talk about the structure of the Earth, where this data comes from, and how this is related to the natural concentration of valuable minerals and sources of energy.
Here, I discuss the global lithium trade, the geology of lithium ore, hint towards some environmental and cultural considerations, and talk briefly about battery types and recycling!
Here, I continue the lecture about global and US Energy usage, go into some of the units used to describe power and energy, and how energy usage is related to "quality of life".
