When granite is subjected to high heat and pressure without melting, it transforms into a metamorphic rock.

Here's why:

* Heat and pressure: These conditions cause the minerals within the granite to recrystallize. This means the existing minerals change their structure and sometimes even their chemical composition.

* No melting: If the temperature doesn't reach the melting point of granite, the rock doesn't become liquid magma.

* New rock type: The recrystallized minerals create a new rock type with different textures and sometimes even new minerals.

Examples of metamorphic rocks formed from granite:

* Gneiss: A banded metamorphic rock with distinct layers.

* Schist: A metamorphic rock with a flaky or platy texture.

* Migmatite: A mixed rock with both igneous and metamorphic characteristics.

So, the answer is metamorphic rock.
