What features form at a hot spot.?
They form volcanic mountains by heating magma that breaks through the crust. On the oceanic plates, these crustal hot spots can form chains of volcanic islands such as the Hawaiian Islands.
At what type of boundary do hot-spot volcanoes form at?
Hot-spot volcanoes form at intraplate boundaries, where a plume of hot magma rises from deep within the mantle, creating volcanic activity away from tectonic plate boundaries.
Is a hot spot a tectonic plate boundary?
it is a hot spot for the boundary because it represents the volcanic eruption
What is a geological hot spot?
A geological hot spot is where hot magma rises from the earth's mantle, which creates volcanic activity.
What evidence would there be that the earth's crust passed over a volcanic hot spot that came from deep inside the mantle?
A string of seamounts or volcanic islands could form.
What is the place where volcanoes form in the middle of plates called?
its called a hot spot, its Region of the Earth's upper mantle that upwells to melt through the crust to form a volcanic feature. Most volcanoes that cannot be ascribed either to a subduction zone or to seafloor spreading at midocean ridges are attributed to hot spots. The 5% of known world volcanoes not closely related to such plate margins are regarded as hot-spot volcanoes. Hawaiian volcanoes are the best examples of this type, occurring near the centre of the northern portion of the Pacific Plate. A chain of extinct volcanoes or volcanic islands (and seamounts), such as the Hawaiian chain, can form over millions of years where a lithospheric plate moves over a hot spot. The active volcanoes all lie at one end of the chain or ridge, and the ages of the islands or the ridge increase with their distance from those sites of volcanic activity.
How is a hot shot formed?
A hot spot is an area of persistent volcanic activity
What is the difference between volcanic island and volcanic arc?
Volcanic arcs form at plate subduction zones. Island arcs are volcanic islands that form over "hot spots" in the Earth's mantle. Because the islands are moving with the oceanic plate, they eventually are removed from the hot spot, forming a chain of islands in the direction of the plate movement.
What is the differences between volcanic island arcs and volcanic arcs?
Volcanic arcs form at plate subduction zones. Island arcs are volcanic islands that form over "hot spots" in the Earth's mantle. Because the islands are moving with the oceanic plate, they eventually are removed from the hot spot, forming a chain of islands in the direction of the plate movement.
When a hot spot stays put but the plate above it keeps moving what happens?
It leaves an island arc or chain if the hot spot is in the ocean. A great example of this is the Hawaiian Island chain. There is another hot spot in the North American plate which now resides in Yellowstone National park. This hot spot simply leaves a chain of extinct volcanic areas as the continental plate moves over it.
How does hot spot form?
A hot spot is formed on a point of the earths surface where strong upward convection currents or plumes of hot magma in the upper mantle push up below the plates of the lithosphere causing volcanic activity. no it doesn'twhen the mantle is weak
Why do oceanic hot-spot volcanos often form a long line of volcanic island?
Because the lithospheric ocean plate moves with plate tectonics over the stationary mantle based hot spot, forming a series of volcanoes.
