Question

Quizplus · Accepted Answer

The pressure-release jointing, exfoliation, and sheeting processes result in the development of dome-shaped features and arches in granitic mountain masses. These processes occur due to the release of pressure on the outer layers of the rock, causing them to expand and crack in a particular pattern, leading to the formation of these unique features.
