How can metamorphic rock transform into igneious?

Metamorphic rock can transform into igneous rock through the process of melting and subsequent solidification. When metamorphic rock is subjected to high temperatures and pressures, it may partially melt, forming magma. If this magma rises to the surface and cools, it crystallizes into igneous rock. Thus, through melting and cooling, metamorphic rock can transition into the igneous rock cycle.
