The south face of the mountain was once part of Iceland's coastline, from which, over thousands of years, the sea has retreated some 5 km (3 mi). The former coastline now consists of sheer cliffs with many waterfalls, of which the best known is Skógafoss. In strong winds, the water of the smaller falls can even be blown up the mountain.
The island of South Georgia is unusual among oceanic islands for having pre-Cretaceous sedimentary rocks underlying much of the island and a significant portion of felsic igneous rocks. Two-thirds of the island consists of intensely folded flysch , capped with Aptian age fossils, tuff and greywacke in the Cumberland Bay Series.
Eyjafjallajökull (pronounced [ˈeiːjaˌfjatlaˌjœːkʏtl̥] ⓘ) is one of Iceland's smaller ice caps located in the far south of the island. Situated to the north of Skógar and to the west of the larger ice cap Mýrdalsjökull , Eyjafjallajökull covers the caldera of a volcano 1,666 m (5,466 ft) high, which has erupted relatively ...
There is an ongoing discussion about whether the hotspot is caused by a deep mantle plume or originates at a much shallower depth. [3] Recently, seismic tomography studies have found seismic wave speed anomalies under Iceland, consistent with a hot conduit 100 km (62 mi) across that extends to the lower mantle.

The Alps form part of a Cenozoic orogenic belt of mountain chains, called the Alpide belt, that stretches through southern Europe and Asia from the Atlantic all the way to the Himalayas. This belt of mountain chains was formed during the Alpine orogeny. A gap in these mountain chains in central Europe separates the Alps from the Carpathians to ...
In recent years, the construction of large-scale solar farms in South and Middle Georgia has become a key part of the state’s energy plans — and crucial if Georgia’s coal plants are to be ...
The Alpine orogeny is caused by the continents Africa, Arabia and India and the small Cimmerian Plate colliding (from the south) with Eurasia in the north. Convergent movements between the tectonic plates (the African Plate, the Arabian Plate and the Indian Plate from the south, the Eurasian Plate and the Anatolian Sub-Plate from the north, and many smaller plates and microplates) had already ...
