the cause of contributing the gravel Pressure, erosion, they can be melted down to form magma, they can cool from magma and form rock, that's a very general question.
Magma is molten meaning liquid-like so it is able to move inside earth. The tectonic plates separate the earth and magma. This explains when the plates move earthquakes and volcanoes occur. Lava is not magma by the way! lava is hardened magma and magma is molten!
Metamorphic rock is not formed directly from magma. Igneous rock is formed from the solidification of magma and lava.
Hot mantle rock rises to fill rift zones. When rock rises, a decrease in pressure causes hot mantle rock to melt and form magma.
Three ways ingenuous rocks form are by magma cooling below, at or beneath the surface. Magma forms when rock is heated, changes composition and/or pressure is released.
The main cause for a rock to melt and form magma is constant pressure and heat in the mantel

the mid ocean ridges cause the magma to form at a convergent plate boundary.

Magma is basicaly the same as lava, except magma is still in the volcano, when magma has come out of the volcano, it has become lava.
Heat and pressure.

they are normally formed inside or very near volcanoes. To form igneous rock magma must cool the it will turn into and igneous rock (intrusive or extrusive)
Yes, all volcanoes erupt because the magma underneath or in the volcano is under pressure, which forces the magma to the surface, where there is less pressure. However, volcanoes form in different places.
