The melting of surface material, like rock, is a gradual process that occurs as tectonic plates subduct (slide under one another). Extreme frictional forces are applied, and this helps to heat the subducted material. Also it is heated increasingly by Earth's internal heat. As this process continues, all the subducted material becomes hot enough to melt to become magma.

Magma is liquid rock that is underground. When it reaches the surface, as through a volcano, it is called lava.

How does magma form ay divergent boundaries?
Hot mantle rock rises to fill rift zones. When rock rises, a decrease in pressure causes hot mantle rock to melt and form magma.
What three types of rocks can melt to form magma?
All types of rock can melt. Thus potentially ALL types of rocks can form a magma. Your question - asking for 3 types, is therefore meaningless.
Can lava melt rock in the mountain?
Underground molten rock, called magma, does melt some of the surrounding rock.
How does magma become a igneous rock?
Igneous rock, if heated sufficiently by subduction processes will melt to form magma.
How does magma affect the rocks into which in intrudes?
Magma is molten rock that bubbles up along ocean ridges to form new crust. Another way that magma forms new crust is when it is expelled out of a volcano and becomes lava, which cools and hardens into crust.
Does magma form when rock begins to melt?
Yes. Magma is underground molten rock.
Name three things that can cause rock to melt and form magma?
The main cause for a rock to melt and form magma is constant pressure and heat in the mantel
How does magma form ay divergent boundaries?
Hot mantle rock rises to fill rift zones. When rock rises, a decrease in pressure causes hot mantle rock to melt and form magma.

What color rocks does basaltic magma form?
Basaltic magma usually forms a black rock.
Can lava melt rock in the mountain?
Underground molten rock, called magma, does melt some of the surrounding rock.
What rock families can form magma if hot enough?
All the three existing rock families/types/classes (ie, igneous, sedimentary and metamorphic rocks) can form magma, if they become hot enough to melt and change to molten form.
How does magma become a igneous rock?
Igneous rock, if heated sufficiently by subduction processes will melt to form magma.
Does rock have to melt in order to change form?
No, if it's with heat like magma or lava, yes, that's what changes it. (:
When rock melt what kind of rocks do they become?
lava also known as magma which is the more scientific form of the word
How does magma affect the rocks into which in intrudes?
Magma is molten rock that bubbles up along ocean ridges to form new crust. Another way that magma forms new crust is when it is expelled out of a volcano and becomes lava, which cools and hardens into crust.
What can't magma melt?
it's alredy melted rock
