Sedimentary rock into metamorphic rock What steps can turn sedimentary rock into metamorphic rock? Step 1 Sedimentary rock is exposed to heat or pressure. Step 2 The sedimentary rock changes into metamorphic rock.
5. What type of rock forms when high heat or great pressure act on sandstone? -Quartzite forms
6. What new type of rock can form after quartzite melts? -the igneous rock andesite 7. Lava, sediment and sand are all produced by the rock cycle.
