Specific term required. One occurrence of this process in the province of Grenville is characterized by AMCG suites. This process can result in the formation of flysch and molasse layers, which fill the foreland basin. Before the development of plate tectonics, geosynclines were invented to explain these processes. This process occurs in the last phase of the Wilson cycle before the (*) rifting stage. It’s not seafloor spreading, but a type of thermal buoyancy called dynamic topography explains how this process can occur at mid-ocean ridges. The closure of the Iapetus ocean caused the Caledonian one of these processes, which occurred earlier than one named for Laramide. This process occurs at namesake belts when two plates crumple and are uplifted at a convergent boundary. For 10 points, name this geologic process that forms mountains. ■END■
ANSWER: orogeny [or orogenesis; accept the Laramide orogeny; accept the Caledonian orogeny; prompt on mountain formation until read; prompt on tectonic plate collision; prompt on convergence or divergence; prompt on crumpling or folding or deformation]
