Each friend shows you one idea by how they act. Meet them all and see how the ideas fit together.
-
Sink Convergent/subduction boundary — the heavier plate finds its way down; it takes a long time; that's okay -
Spread Divergent boundary + new crust — when something pulls apart, something new is forming in the middle -
Slide Transform boundary + stored energy — two plates sliding past; they catch, they hold, then they let go -
Vent Volcanism + magma chemistry — eruptions tell us what was happening below -
Tremor Seismology + earthquake preparedness — earthquakes are the Earth telling its story; we can read the lines; we can be ready -
Churn Mantle convection — the engine that drives the plates — 'Deep heat moves the whole map.' -
Heave Mountain-building — folding + uplift at collisions — 'Push long enough and mountains rise.' -
Remake The rock cycle — igneous, sedimentary, metamorphic — 'Nothing is ever really finished.' -
Scour Weathering + erosion — wearing down the land — 'Water and time win.' -
Silt Deposition + strata — reading rock layers as time — 'Every layer is a page.'
