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.

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.
Where does magma come from?
It comes from the Magma Chamber in the bottom of the volcano. :)
What is openings in Earth's crust that allows magma to reach the surface called?
The opening of the crust where magma is allowed to reach to the surface is called a fault line.
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

How is a divergent fault formed?
When magma pushes 2 plates apart. :)
How Do The Plates Move Of The Normal Fault?
Tectonic plates float on the magma of the Earth's mantle, and move because of convection currents in the magma.

Magma that forces its way into rocks and hardens is called a extrusion or fault or unconformity or intrusion?
Magma that forces its way into rocks and hardens is called intrusion.

When magma erupts what does it go through?
It goes through, a fault, crack, vent or hole on a volcano.
When magma is come out known as?
lava
What igneous rocks come from?
