Fault-block mountain of the tilted type. [16] Sierra Nevada Mountains (formed by delamination) as seen from the International Space Station. When a fault block is raised or tilted, a block mountain can result. [17] Higher blocks are called horsts, and troughs are called grabens. A spreading apart of the surface causes tensional forces.
Examples are mountains, hills, polar caps, and valleys, which are found on all of the terrestrial planets. The scientific study of landforms is known as geomorphology. In onomastic terminology, toponyms (geographical proper names) of individual landform objects (mountains, hills, valleys, etc.) are called oronyms. [4]

Mountains and hills can be characterized in several ways. Some mountains are volcanoes and can be characterized by the type of lava and eruptive history. Other mountains are shaped by glacial processes and can be characterized by their shape. Finally, many mountains can be characterized by the type of rock that make up their composition.
These are new openings formed on the sides of the volcano through which new material is ejected sometimes only on one side. As a result, these mountains lose their ideal conical shape. The formation of an almost perfect conical mountain or hill is only possible where there is a stable, central crater.

The word inselberg is a loan word from German, and means "island mountain". The term was coined in 1900 by geologist Wilhelm Bornhardt (1864–1946) to describe the abundance of such features found in eastern Africa. [3] At that time, the term applied only to arid landscape features.
