No. If a rock melts and then re-solidifies the result is counted as igneous, not metamorphic.
It begins with melting.

Yes, the cooling of lava from the volcano creates the process of metamorphism; in this case - the rock.

The process of melting transforms gneiss, a metamorphic rock, into magma by subjecting it to high temperatures and pressure deep within the Earth's crust. This causes the minerals in the gneiss to melt and form a molten liquid called magma.
No, a metamorphic rock cannot be created through melting. Metamorphic rocks form from existing rocks—either igneous, sedimentary, or other metamorphic rocks—through a process called metamorphism, which involves heat, pressure, and chemically active fluids, but not melting. If a rock melts, it transforms into magma, which upon cooling can form igneous rock instead. Therefore, while heat is involved in both processes, melting is a key distinction that separates the formation of igneous rocks from metamorphic ones.
Metamorphic refers to the process by which rocks are changed by heat, pressure, or fluids into new forms, without melting. This process typically occurs deep underground in the Earth's crust.
Metamorphic rocks can form at temperatures lower than the melting point of rock because they do not actually melt during the process. Instead, they recrystallize under high pressure and temperature conditions, causing changes in mineral composition and texture. This process allows metamorphic rocks to form without reaching the point of melting.
The melting of metamorphic or igneous rock forms magma.
