Troll_Wall | TriviaQuestions.online

⭐ In the context of cliffs, which geological process contributes significantly to their formation alongside weathering and erosion?

Cliffs are formed when gravity acts upon rock that has been weakened by weathering and erosion, causing it to break away and create a steep, vertical face.

⭐ Core Definition: Troll Wall

The Troll Wall (English) or Trollveggen (Norwegian) is part of the mountain massif Trolltindene (lit. 'Troll Peaks') in the Romsdalen valley in Rauma Municipality in Møre og Romsdal county, Norway. It is located to the south of the towns of Åndalsnes and Molde inside the Reinheimen National Park.

The Troll Wall is the tallest vertical rock face in Europe, about 1,100 metres (3,600 ft) from its base to the summit of its highest point. At its steepest, the summit ridge overhangs the base of the wall by nearly 50 metres (160 ft). The Rauma River, the Rauma railway and the European Route E136 run just to the east of the wall.

👉 Troll Wall in the context of Cliff

In geography and geology, a cliff or rock face is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs.

An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers.
