What are examples of volcanic hotspots?
Major hot spots include the Iceland hot spot, under the island of Iceland in the North Atlantic; the Réunion hot spot, under the island of Réunion in the Indian Ocean; and the Afar hot spot, located under northeastern Ethiopia. Volcanic activity at hot spots can create submarine mountains known as seamounts.
How is a hotspot volcano described?
A volcanic “hotspot” is an area in the mantle from which heat rises as a thermal plume from deep in the Earth. This melt, called magma, rises through cracks and erupts to form volcanoes. As the tectonic plate moves over the stationary hot spot, the volcanoes are rafted away and new ones form in their place.
Which of the following is a good example of a hot spot beneath an oceanic plate?
Most hotspots, also known as “mantle plumes,” occur beneath oceanic plates; Yellowstone, however, is a good example of a hotspot beneath a continental part of a plate.
What are two characteristics of volcanic hotspots?
Some hot spots produce volcanoes. molten, or partially melted, rock beneath the Earth’s surface. upwelling of magma within Earth’s mantle. single, upward flow of a fluid, such as water or smoke.
Is Mt Pinatubo over a hotspot?
It was June 15, 1990, when Mount Pinatubo, on the island of Luzon in the Philippines, awoke from its 500-year slumber to produce the second largest volcanic eruption of the 20th century. Like most volcanoes, Mount Pinatubo is located along the boundary of tectonic plates. …
How many hotspots are there?
To be classified as a biodiversity hotspot, a region must have lost at least 70 percent of its original natural vegetation, usually due to human activity. There are over 30 recognized biodiversity hotspots in the world.
What plate boundary is Taal Volcano on?
Taal Volcano is part of a chain of volcanoes lining the western edge of the island of Luzon. They were formed by the subduction of the Eurasian Plate underneath the Philippine Mobile Belt. Taal Lake lies within a 25–30 km (16–19 mi) caldera formed by explosive eruptions between 140,000 and 5,380 BP.
Which is the best example of a hotspot volcano?
A “hotspot” is an area in the Earth’s mantle from which hot plumes rise upward, forming volcanoes on the overlying crust. The best example of a hotspot producing a line of volcanic islands is the Hawaiian hotspot.
Which is the best simile for a volcano?
Volcano Similes. by Shepards “Volcanoes are as beautiful as fireworks” “The plates are like a giant jigsaw puzzle.”. “Magma breaks through by rising through cracks like chimney flues.”. “Some lava flows as quickly as cars in city traffic.”.
How does magma form in a hot spot?
Volcanic hot spots are plumes of molten rock which rise from the mantle and cause the crust to melt, creating magma resulting in volcanic activity. The map below shows the location of volcanic hot spots. The diagram below illustrates the formation of a hot spot and its associated landforms.
Where are volcanic hot spots in the world?
For example, the Hawaiian volcanic islands, located in the middle of the Pacific Plate, are formed due to a hotspot. Volcanic hot spots are plumes of molten rock which rise from the mantle and cause the crust to melt, creating magma resulting in volcanic activity. The map below shows the location of volcanic hot spots.
