A hotspot's position on the Earth's surface is independent of tectonic plate boundaries, and so hotspots may create a chain of volcanoes as the plates move above them. There are two hypotheses that attempt to explain their origins. One suggests that hotspots are due to mantle plumes that rise as thermal diapirs from the core–mantle boundary. [2]
Attendees to the Mapping for Change International Conference on Participatory Spatial Information Management and Communication conferred to at least three potential implications of PPGIS; it can: (1) enhance capacity in generating, managing, and communicating spatial information; (2) stimulate innovation; and ultimately; (3) encourage positive social change.
The hotspot's most recent caldera-forming supereruption, known as the Lava Creek Eruption, took place 640,000 years ago and created the Lava Creek Tuff, and the most recent Yellowstone Caldera. The Yellowstone hotspot is one of a few volcanic hotspots underlying the North American tectonic plate; another example is the Anahim hotspot.
Biodiversity hotspots host their diverse ecosystems on just 2.4% of the planet's surface. [2] Ten hotspots were originally identified by Myer; [1] the current 36 used to cover more than 15.7% of all the land but have lost around 85% of their area. [8]
The volcanism is caused by the African plate moving slowly over a hotspot in the Earth's mantle. A hotspot (the Canary hotspot) is the explanation accepted by most geologists who study the Canary Islands. [34] [35] A relatively hot mantle plume associated with this hotspot is thought to be rising through the mantle under La Palma and El Hierro ...
The study of the causal relations of the phenomena present in a region; a comprehensive explanatory study of a region.
