What happens at a hotspot?
Hotspots are locations that are prone to volcanic activity.
Why is Hawaii volcanic even though it does not lie on a fault line?
because it lies on a hotspot inside the pacific plate
What is an example of a sudden geologic process?
volcanic eruption
An example of a caldera is?
It is a cauldron-like volcanic feature usually formed by the collapse of land fallowing a volcanic eruption.
What is a example of a volcanic mountain?
mount Kilimanjaro mount Fuji
How was fernandina formed?
The Galápagos hotspot is a volcanic hotspot in the East Pacific Ocean responsible for the creation of the Galapagos Islands.
What happens at a hotspot?
Hotspots are locations that are prone to volcanic activity.
What is in the north Atlantic Ocean is a volcanic island formed over a hot spot on a divergent plate boundary?
I believe this is Iceland, however it is not necessarily a hotspot as such, as notable hotspots do not occur on plate boundaries. An example of a hotspot is under Hawaii and neighbouring islands.
What is an area of volcanic activity far from a tectonic plate boundary?
mantle plume
What does a fixed volcanic hot spot on Earth tend to produce?
a fixed volcanic hot spot on Earth tends to produce a volcano like chain. take Hawaii as an example, as the Earth's crust moves along, it makes the hotspot seem to move. The hotspot doesn't move, but it just tends to create a different volcanic mountainous structure relatively close to the last location. these volcanoes tend to be very calm, allowing people to live near them if given the right circumstances
Hawaii is on what kind of fault?
Actually, it was a volcanic hotspot in the middle of the Pacific Plate that formed the island chain.
Why Hawaii is made of volcanoes due to?
The Hawaiian Islands formed over a hotspot in the Pacific Ocean, where magma formed a column and rose through the Earth's crust, causing volcanic activity. The hotspot stays fixed as the Earth's plates move over it, which is why, currently, no island but the Big Island experiences volcanic eruptions.
Why is Hawaii volcanic even though it does not lie on a fault line?
because it lies on a hotspot inside the pacific plate
What is the name of Geological hotspot that New Zealand lies on?
The Taupo Volcanic Zone is its formal name, with extensive active centres.
What are groups of volcanoes called?
If it is a single island, it is simply known as a volcanic island! If however it is a chain or string of separate islands then it may be a volcanic island arc (these form parallel to trenches at subduction zones) or a volcanic island chain (these form where a mantle plume creates a hotspot and may be in the centre of a tectonic plate. A good example would be the Hawaiian island chain). They can also form a cluster of islands (an archipelago) such as the Canary Islands (again formed by hotspot volcanism) in the Atlantic of the coast of Morocco.
Is ruapehu a hotspot?
Yes, Ruapehu is indeed a hotspot. Located in the North Island of New Zealand, Mount Ruapehu is an active stratovolcano and is considered one of the most active volcanic areas in the country. A hotspot refers to a location on Earth's surface where volcanic activity is concentrated. This volcanic activity is caused by a plume of hot magma rising from deep within the Earth's mantle. One of the key pieces of evidence supporting Ruapehu's hotspot status is its frequent eruptions. Since 1861, the volcano has erupted at least 60 times, with the most recent eruption occurring in 2007. These eruptions often result in the expulsion of ash, gases, and occasionally lava flows. Furthermore, the presence of geothermal activity in the region also indicates the hotspot nature of Ruapehu. Hot springs, fumaroles, and mud pools are common features found around the volcano. These geothermal manifestations are a result of the underlying heat source provided by the volcanic hotspot. Ruapehu's hotspot status is not only of scientific interest but also has significant implications for tourism and outdoor activities in the region. The volcano's stunning landscape and the availability of skiing and snowboarding opportunities on its slopes attract numerous visitors every year. In conclusion, Ruapehu is indeed a hotspot due to its frequent volcanic activity, the presence of geothermal features, and its popularity as a tourist destination.
Why don't flood basalts build volcanic cones?
Flood basalts build volcanic cones because flood basalts are believed to originate when the head of a mantle hotspot first arrives beneath the base of a plate. Because of this, they are unable to build volcanic cones.
