Transformation by Heat
Transformation by Heat is a skill on Pengi from Lesson 3: Subduction and Melting in Amplify Science (California) Grade 7.
Key Concepts
Depth equals heat. As rock descends further during subduction, it absorbs increasing amounts of thermal energy from the surrounding mantle.
Eventually, the temperature overwhelms the rock's solid structure, causing a phase change. The solid rock melts into liquid magma . This completes the loop: material that once existed as cold sediment on the ocean floor is returned to a molten state, ready to begin the cycle again.
