8. GEOL 325 Lecture 22 Appalachians The Earth has a molten interior on which the crust and mantle float Crust 3-70 km Mantle 2900 km Core 3486 km

9. GEOL 325 Lecture 22 Appalachians Mosaic of Drifting Rigid Plates After Dennis. Tassa

10. GEOL 325 Lecture 22 Appalachians Appalachians exhibit Wilson Cycle  Plate tectonic theory divides earth’s crust into plates  Plates diverge apart or rift & a new ocean basin forms  Plate motion reverses & convergence causes collision, & mountain building  The Wilson Cycle records plate motion opening & closing of ocean basins in the rock record
