Which process contributes to the formation of metamorphic rocks when hot magma or lava contacts other rocks?

The process that contributes to the formation of metamorphic rocks when hot magma or lava contacts other rocks is fusion. This process involves the melting of existing rocks due to the intense heat of the magma or lava. As the surrounding rocks are heated, they begin to partially melt and undergo chemical changes, leading to the formation of metamorphic rocks.

The result is the transformation of the mineral composition and texture of the original rock, distinguishing metamorphic rocks from their parent rocks. This process is critical in regions where igneous intrusions occur, allowing geological formations to evolve and develop new characteristics.
