What is a weak spot in the earth's crust where magma has come to the surface?
The answer to this question is called an active volcano.
What is a word that means a weak spot in the crust where magma comes to the surface?
In the crust the weak spot we have is the Magma Chamber. But, deep down to the mantle such weak zone is the Asthenosphere.
What is the weak spot in the crust where magma has to come up?
Volcano
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 causes magma to flow out of a weak spot in the earths crust?
Magma flows out of a weak spot in the Earth's crust due to the build-up of pressure from the molten rock beneath the surface. This pressure can result from the heat and movement of tectonic plates, creating pathways for magma to rise and eventually erupt onto the surface as lava.
What is the definition for hot spot?
A hot spot is a location where there is a significant amount of activity or concentration of a particular phenomenon. This term is often used in reference to areas with high levels of criminal activity or intense geological activity, such as volcanic regions.
What is an area where magma melts through the crust in the middle of a plate?
A hot spot is an area where magma from deep within the mantle rises through the crust in the middle of a tectonic plate, creating volcanic activity and forming a chain of volcanic islands or seamounts. The Hawaiian Islands are a well-known example of hot spot activity.
Where is the earth's crust do most volcanoes erupt?
well mostly along plate boundarys but there can be "hot spots" in the mantle that magma come out of. for ex:hawii is right over a hot spot well mostly along plate boundarys but there can be "hot spots" in the mantle that magma come out of. for ex:hawii is right over a hot spot
What causes the magma to flow out the weak spot in the earth surface?
Magma flows out of weak spots in the Earth's surface due to built-up pressure from molten rock beneath the surface. This pressure eventually overcomes the resistance of the weak spot, allowing the magma to rise and reach the surface as a volcanic eruption. The type of volcanic eruption depends on the composition of the magma and the characteristics of the weak spot.
What is a hot spot in relation to volcanoes?
This is a point in the Earth's crust where hot upwellijng mantle material causes significant magma formation and melting to occur within the crust and upper mantle. This in turn causes hotspot volcanism at the surface.
What is an area where magma from deep within the mantle melts through the crust above?
Hot spot.
A weak spot in the crust where magma comes through?
A weak spot in the Earth's crust where magma rises to the surface is known as a volcano. This molten rock can erupt explosively or flow steadily, forming new land formations like lava flows or volcanic mountains. Volcanoes are typically found along tectonic plate boundaries but can also occur in hotspots within the Earth's mantle.
