An extra 10 points to Damian in that piece for using the word "orogeny", which I'm embarrassed to say
Scientist said that Halong bay has experienced at least 500 million years in various of ancient geographic condition such as orogeny, marine transgression and marine regression.
Alternately, the Galician-Portuguese Western extreme of the ecoregion is characterized by lower smooth elevations, which correspond to very old massifs shaped by the late Paleozoic Hercynian orogeny.
Many ridges are formed on well-cemented, relatively resistant material such as sandstone or conglomerate; they are often rather parallel and alternate with valleys but, in central Pennsylvania, they zigzag because resistant strata were compressed into plunging folds during orogeny and later eroded.
Neotropical floristic diversity: Phytogeographical connections between Central and South America, Pleistocene climatic fluctuations, or an accident of the Andean orogeny.
This range was shaped by an intense Alpine orogeny into a complex landscape characterized by steep rocky slopes, amazing canyons, karstic high plains, and high summits.
In this orogeny, compressional forces squished sedimentary deposits that existed between the converging continental plates and rocks at the margin of the Eurasian and Indian plates upward in elevation.
This is the northernmost and wettest of the central Asian depressions, remnants of a Tertiary era inland sea, with relict glaciers, glacier lakes and a wide variety of rock types, the result of a long series of successive eras of deposition and orogeny.
These mountains are part of the western Iberian old Hercynian system, which constitutes medium elevations with a smooth relief, scarcely influenced by the Alpine orogeny.
The Alpine orogeny has shaped the complex Pyrenean landform.
