Answer 1

Temperature.

High Temperatures and pressures is a process called metamorphism, thus, temperature would be the answer

Answer 2

Answer:

Sedimentary rocks are changed to metamorphic rocks due to subduction and temperature.

Explanation:

• Metamorphic rocks are made up of other existing rocks like Igneous rocks and Sedimentary rocks.

• When the existing rocks are subjected to enough pressure and temperature, they undergo permanent deformation and are turned into metamorphic rocks.

• The pressure exerted on the already existing rocks is mainly due to the subduction activity of the plates. The formation of metamorphic rocks mainly occurs below the Earth's surface.
