What causes magma to form at hot spots?
A volcanic hot spot forms from upwelling magma usually due to the subduction of a tectonic plate. As plates move over this area new volcanoes are formed. +++ A hot spot alone is the top of a convection plume in the Mantle, not above subduction. This type of hot spot can lead to continental rifting.
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.
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.
Why do volcanoes at a hot spot eventually become extinct?
The plate that the volcano is on moves while the hot spot does not. The volcano is eventually carried away from the hot spot and no longer has a source of magma.
What state was formed from a hot spot?
Hawaii was formed from a hot spot, which is a location where hot magma rises from deep within the Earth and creates volcanic activity on the surface over a stationary point. The magma formed the Hawaiian Islands as the Pacific tectonic plate moved over the hot spot.
What features form a hot spot volcano form?
magma
What causes hot spot volcanoes form?
Magma from deep within the mantle melts through the crust which is what causes hot spot volcanoes to form
How did hawaiin islands form?
The Hawaiian Islands were formed by a hot spot in the middle of the Pacific Plate. Hot magma rises upward until it spills onto the sea floor, forming a hot spot.

Why do volcanoes form in certain regions of earth's surface?
A volcano is technically a weak spot in Earth's crust where molten material like magma reaches the surface. Magma is made near the surface by convergent (colliding) or divergent (spreading) boundaries. Most volcanoes form near convergent boundaries where the oceanic plate submerges because of the density of the plate.Also, a hot spot may form a volcano. A hot spot is where magma from the mantle reaches the surface. As the crust moves from convection currents in the mantle, the hot spot is near the crust. Whenever the hot spot passes under a weak spot in the crust, the pressure in the magma is strong enough to push through. As the crust continues moving, the hot spot makes different volcanoes in a row, called an island arc. An example of this is Hawaii.
What is a geological hot spot?
A geological hot spot is where hot magma rises from the earth's mantle, which creates volcanic activity.

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
What features form a hot spot?
A hot spot is in earths mantle.a hot spot is an area where material from deep within the mantle rises and then melts, forming magma and volcano forms above a hot spot when magma erupts and reaches the surface.
