The planet from its core to its storms, with pins you stick in a 3D globe: four layers down, continents that drift 2.5 cm a year, Iceland, Everest and the San Andreas, the biggest earthquakes on record, Mauna Loa, Fuji and Vesuvius, what to do when the ground shakes or the sea drains away, rocks and their cycle, a 4.54-billion-year-old Earth, the air's five layers, the water cycle, fronts, hurricanes, tornadoes and lightning.
