Relative Dating - working out what happened first, second...
How does a geologist work out the sequence of events when looking at outcrop? How do uniformitarianism, superposition, fossil sequences, and cross-cutting relationships all tie together to work out what came first and what came last? This episode I talk through the processes for sedimentary, igneous and metamorphic rocks and structures like faults, folds, and unconformities.
All of that in just 12 mins!
