Amethyst is an igneous rock. It is quartz which has been stained purple by mineral impurities.
Amethyst is a variety of quartz, which is a mineral that is formed in igneous and metamorphic rocks. Amethyst is typically formed in hydrothermal veins within igneous rocks or as a product of metamorphism in rocks rich in silica. Therefore, amethyst is not classified as a specific rock type, but rather a mineral that can be found in both igneous and metamorphic rocks.
The melting of metamorphic or igneous rock forms magma.
An igneous rock can be metamorphosed (changed) into a metamorphic rock but will no longer be an igneous rock. An igneous body can be intruded into metamorphic rocks but will still be an igneous rock that is different from the surrounding metamorphic rocks. Ethier answer work depending on how the question is read.
actually, it truly depends on the type of rock the metamorphic rock formed from. in other words, if it formed from a rock that held basalt in it, the rock has basalt in it. remember that a metamorphic rock can be formed by more than two different types of rock (such as metamorphic quartz, slate, "fool's gold", plus granite). it does not matter which class the metamorphic rock formed from (but if a m. rock such as m. quartz, there is more likely a chance of finding a trace of basalt), as long as it formed from two different class of rock (this does not always apply, for there can be a metamorphic rock made from two or more metamorphic rocks). i would get into geodes...... but that's another answer. :)
No, sodalite is a metamorphic mineral, not a rock. It is a blue mineral commonly found in igneous rocks like syenite or nepheline syenite.

Metamorphic rock becomes igneous rock when it is melted, then solidifies.
A metamorphic rock can become a igneous rock by melting and cooling
Any metamorphic rock can melt and recrystallize and become an igneous rock.
The metamorphic rock melts into magma then cools into igneous rock
The melting of metamorphic or igneous rock forms magma.
No, metamorphic can be formed by either igneous or sedimetary rock.
Yes. A metamorphic rock can melt and the re-solidify as an igneous rock.
if the igneous rock is put under heat and pressure it turns into a metamorphic
metamorphic rock
it is a metamorphic rock
It is a Metamorphic rock
