Volcanic crater lake – Lake formed within a volcanic crater; Subglacial mound – Volcano formed when lava erupts beneath a thick glacier or ice sheet; Submarine volcano – Underwater vents or fissures in the Earth's surface from which magma can erupt; Supervolcano – Volcano that has had an eruption with a volcanic explosivity index (VEI) of 8
Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type.Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains ...
Volcanic rock types found on the Canary Islands are typical of oceanic islands. The volcanic rocks include alkali basalts, basanites, phonolites, trachytes, nephelinites, trachyandesites, tephrites and rhyolites. [18] [3] There are lava flows as well as deposits of pyroclastic material, such as tuff (made of volcanic ash or lapilli).
A hotspot volcano is center. [8] Movements of tectonic plates create volcanoes along the plate boundaries, which erupt and form mountains. A volcanic arc system is a series of volcanoes that form near a subduction zone where the crust of a sinking oceanic plate melts and drags water down with the subducting crust. [9]
The volcanic belt also contains three large shield volcanoes that were formed between 8 and 1 million years ago, called the Ilgachuz Range, Rainbow Range and the Itcha Range. The Chilcotin Group in southern British Columbia is a north–south range of volcanoes, thought to have formed as a result of back-arc extension behind the Cascadia ...
The cone itself is a volcanic edifice, representing complex interaction of intrusive igneous rocks with the surrounding salt. [10] Lake "Veľké Hincovo pleso" in High Tatras , Slovakia . The lake occupies an " overdeepening " carved by flowing ice that once occupied this glacial valley.

Satellite image of the Big Raven Plateau in British Columbia, Canada Rangipo Desert of the North Island Volcanic Plateau. Numerous tephra layers are visible. The Pajarito Plateau in New Mexico, United States is an example of a volcanic plateau. A volcanic plateau is a plateau produced by volcanic activity. There are two main types: lava ...
