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.

Which part of the Earth is the source of magma?
Lava is magma that reaches the surface. Magma originates either from rising plumes of heat at hot spots in the Earth's mantle, where decompression melting takes place as the hot rock nears the surface; or, it originates in the mantle from subduction of oceanic crust, where cold, wet rock speeds melting of the subducting rock and it rises toward the surface.
Why does magma rise through the crust above it?
Pressure builds in the magma chamber forcing it upward through faults in the crust
Lava and magma?
Magma is molten material under the Earths crust with temperatures between 700-1300 degrees. Lava is the magma that reaches the surface and exits the volcano.
What is slow cooling magma far beneath earth's surface?
The slow cooling of magma far beneath earth's surface creates the rock inside earth to change slowly... this means that earths surface changes in times because of this cooling magma.
What word means fractured surface in Earth's crust where a mass of rock is in motion?
Fault.

What are some properties of magma?
Magma has a lot of different properties. it also means lava. It is in the mantlle if it is called magma, lava is when it is on the earths crust.
What causes magma to rise to earths surface?
The magma is in the mantle, the layer under the crust. There is a convection current caused by radioactivity in the inner core which causes the plates to move. Therefore the constructive plates move apart which means magma can rise up. It'll then solidify and this is what makes volcanoes. Hence CONSTRUCTive.
Why is the earths crust is so important for human life to exist?
We live on the earth's crust that floats on molten magma. Which means we couldn't exist if there was no crust!
What is crust?
the outer layer of the earth
What is another word for magma?
Magma doesn't have an antonym, in that there is no word or expression that means its direct opposite.That being said, magma on the surface (as opposed to underground) is called lava; and once it cools, it's called lava rock or igneous rock.The other parts of the planet (i.e. not the magma) are the crust and the core. Perhaps one of these terms is what you were looking for.
What is slow cooling magma far beneath earth's surface?
The slow cooling of magma far beneath earth's surface creates the rock inside earth to change slowly... this means that earths surface changes in times because of this cooling magma.
How does the stress in Earth's crust change the surface?
it means earthquakes will happen more often
What word means fractured surface in Earth's crust where a mass of rock is in motion?
Fault.
What is the difference between a intrusive igneous rock ad an extrusive rock?
instrusive is inside the valcano and exstrusive comes onto earth's crust
