Mountain formation occurs due to a variety of geological processes associated with large-scale movements of the Earth's crust (tectonic plates). [1] Folding , faulting , volcanic activity , igneous intrusion and metamorphism can all be parts of the orogenic process of mountain building. [ 2 ]
Lagoon – Shallow body of water separated from a larger one by a narrow landform; Lake – Large inland body of relatively still water; Lava dome – Roughly circular protrusion from slowly extruded viscous volcanic lava; Lava – Molten rock expelled by a volcano during an eruption; Lava lake – Molten lava contained in a volcanic crater
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]
[3] Queen Victoria's Rock on the Isle of Barra is a rock formation near Northbay on the north side of the A888, looking toward the west, which resembles the profile of the elderly Queen Victoria. [4] The Winking Man Rock formation (also known as the Winking Eye [5]) is part of the Ramshaw Rocks section of The Roaches.
Fold mountains form in areas of thrust tectonics, such as where two tectonic plates move towards each other at convergent plate boundary.When plates and the continents riding on them collide or undergo subduction (that is – ride one over another), the accumulated layers of rock may crumple and fold like a tablecloth that is pushed across a table, particularly if there is a mechanically weak ...

Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') is the scientific theory that Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago. The model builds on the concept of continental drift, an idea ...
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.
