Most fault movement is not directly associated with magma release. Some faults are caused by magmatic forces. These are usually closely associated with volcanoes. Besides these, so called normal faults are often associated with the extension or stretching of continents. Africa's rift valley and the American Basin and Range province are zones of extension. The stretching thins the crust and provides passageways for magma. Dikes, metal deposits, and lava eruptions can result, and they will be closely associated with faults. Besides these cases, over a wider range fault zones and volcanic zones often coincide because plate collisions produce both features.
What else can I help you with?
Why do volcanoes don't form along the San Andreas Fault?
Volcanoes don't form along the San Andreas Fault because it is a strike-slip fault. This means that neither plate is being subducted under the other--they are just sliding past each other. Because of this, there is no magma, or a way for the magma to come up.
When the break in the inner crust is not filled with magma it is called a?

Where does granite come from?
magma
What happens to the surface at a strike slip fault?
The rock gets farther a part from the fault
What is a volcanic fault?
A volcanic fault is a fracture in the Earth's crust that occurs due to the movement of molten rock or magma beneath the surface. These faults can cause earthquakes and volcanic eruptions when there is significant pressure and stress built up along the fault line.

How is a divergent fault formed?
When magma pushes 2 plates apart. :)
Where does granite come from?
magma

When magma erupts what does it go through?
It goes through, a fault, crack, vent or hole on a volcano.
What igneous rocks come from?
Magma
When magma is come out known as?
lava
Why volcanoes do not form along San A ndreas fault?
The San Andreas fault is a transform fault, meaning that two plates are sliding pas one another. This sort of movement does not force magma toward the surface.
WHEN MAGMA reachesthe surfacegases out of it?
Yes, gases do come out and then the magma under the Earth's crust.
What type of fault line is the mid-Atlantic ridge and why?
Divergent. This is because the two fault lines are pushing away from each other which allows the magma to come up through the crust from the mantle and core. This is what makes the volcanos which create islands such as Iceland.
