You just read a rock column the way a geologist does. Take those cross-cutting and superposition instincts back to the lessons behind them.
Lesson
Layers of Time
Return to the home lesson and revisit how geologists use rock layers to reconstruct the order of Earth's history.
Lesson
Earth's Layers
Zoom out from a single outcrop to the whole planet. See what lies beneath the rock columns you just decoded.
Lesson
Plate Tectonics
The folds, faults, and intrusions you sorted come from moving plates. See the mechanism that rearranged the rock.
