How can a metomorphic rock become an igneous rock?

Metamorphic rocks can become igneous rocks through a process called remelting or partial melting. When metamorphic rocks are subjected to extreme heat and pressure, they can melt and form magma or molten rock. This magma can then cool and solidify to form igneous rocks. The type of igneous rock that forms depends on the composition and conditions of the magma, such as temperature and pressure. For example, if the magma cools slowly underground, it may form plutonic igneous rocks such as granite or gabbro. If the magma cools quickly on the surface, it may form volcanic igneous rocks such as basalt or rhyolite.
