Rocks, plates and the planet's deep history.
Geology deals in timescales that make human history look instantaneous, and reading a landscape properly means learning to see the process behind the shape. This category covers the structure of the planet from crust to core, the three rock families and how each forms, and the plate movements that arrange continents and cause most earthquakes and volcanoes. It also covers how the record is dated and read. The explanations connect surface features to the slow processes underneath, which is the point at which landscapes stop looking arbitrary.
