These are three theorized causes of. answer choices. changing of the climate. movement of the tectonic plates. glacial melting. high and low ocean tides. WitrynaTerranes and Mountain Building Accretion and orogenesis As oceanic plates move, they carry embedded oceanic plateaus, island arcs, and microcontinents to Andean-type subduction zones. Thick oceanic plates carrying oceanic plateaus or “lighter” igneous rocks of island arcs may be too buoyant to subduct.

Witrynaisland arc, long, curved chain of oceanic islands associated with intense volcanic and seismic activity and orogenic (mountain-building) processes. Prime examples of this form of geologic feature include the Aleutian-Alaska Arc and the Kuril-Kamchatka … WitrynaThe most prominent example of this type of mountain building is the Himalayan mountain range. The Indian subcontinent collided with the Eurasian plate, causing the uplift of the Himalayas. ... and they are associated with the formation of volcanic arcs and island arcs.
