Concept Map: Plate Tectonics - Coggle Diagram
Concept Map: Plate Tectonics
Tectonic Plates “rigid slabs of lithosphere that move on the asthenosphere”
Plate Boundaries “locations where adjacent plates interact”
Convergent Boundaries “plates move toward each other (compression)”
Subduction Zones “denser oceanic plate sinks beneath lighter plate”
Magma “slab melts & rises through mantle”
Volcanoes “eruption of magma at surface”
Earthquakes “brittle failure as plates collide & descend”
Divergent Boundaries “plates move apart (tension)”
Mid‑Ocean Ridges “spreading center where new crust forms”
Seafloor Spreading “steady addition of basaltic crust pushes plates away”
Paleomagnetism “magnetic stripes record symmetric seafloor growth”
Transform Boundaries →“plates slide laterally (shear)”
Earthquakes “energy released when locked faults suddenly slip”
Continental Drift “continents change position over geologic time”
Fossil Records “identical land fossils on now‑distant continents”
Seafloor Spreading (above) “mechanism that moves continents with their plates”
Hotspots “stationary mantle plumes independent of boundaries”
Magma (plume) “columns of melt pierce moving plate”
Volcanoes “age‑progressive island/sea‑mount chains (e.g., Hawai‘i)”
