Which of the following best explains the role of heat and pressure in the rock cycle? the molten rocks solidify by this process. the sediments are deposited by this process. they change the mineral composition of rocks. they transport sediments from one place to another.

Heat is essential in melting rocks. Once the preexisting rock melts and then cools inside or on the earth's crust igneous rocks are formed. Heat and pressure are essential in the process of metamorphism. Heat can create new rocks from preexisting rocks by a process called contact metamorphism, forming rocks such as hornfels. Pressure can create foliated rocks such as schist's, slate and gneiss
