Question

which set of factors changes igneous or sedimentary rock into metamorphic rock?
heat and pressure
water and weathering
heat and weathering
water and pressure

Explanation:

Metamorphic rocks form when existing rocks (igneous or sedimentary) are subjected to high heat and pressure. This process, called metamorphism, changes the mineral composition and texture of the rock. Water and weathering are more associated with processes like erosion and sedimentation. Heat and weathering or water and pressure do not accurately describe the formation of metamorphic rocks.

Answer:

heat and pressure
