For 10 points, name these geologic events which form mountains.
Flysch and molasse accumulate in structures that form ahead of and parallel to these events; those structures, which become folded due to dÃ©collement, are called foreland basins. The geometry of this process can be explained using a "critically tapered wedge." Granitic batholiths are usually formed during this process. These events occur in a cyclical fashion in which material is deposited into a geosyncline, then deformed and metamorphosed, and finally (*) uplifted back towards the surface and subjected to erosion. This process, which occurs in namesake "belts," is aided by isostasy, which causes a layer of crust to rise after the collision of two tectonic plates.
