Yes they are .That is why magma which is melted rock material forms Igneous rocks.
Yes, at a sufficiently high temperature, all rocks can be melted.
It is an irreversible change as the rocks break down and we can't bring them back as they were before.
Greenish-black to black.
Many events affect the shape of rocks. They are melted by the heat of the Earth's interior, they are broken by various impacts, and worn away by rubbing against other rocks, etc.
Of coarse, magma is a melted mixture of rocks.
Yes it is
Yes because it can be melted then cooled
no if something is melted then it may be reversible, depending on what it is, but if you cook anything it will be an irreversible change
it is a bit obvious that it is reversible because of when it is hard you burn it and freeze it all the time and it will still be the same.
Yes, at a sufficiently high temperature, all rocks can be melted.
Igneous rocks.
igneous rocks

Yes it is reversible.
igneous rocks- rocks that are formed from melted minerals. ore-a rock that has a large amount of minerals.
Metamorphic rocks
metal melting is a reversible change because as soon as you make the melted metal and freeze it, it might not come back the way it was but at least it is still the same metal material that you had.
