Answer:
1. Which process changes igneous rock into metamorphic rock?
The temperature, pressure, or fluid environment change, and the igneous rock changes its form and becomes metamorphic.
2. Which process changes sedimentary rock into igneous rock?
With tremendous heat and pressure, the sedimentary rock will melt and be back again to magma. After some time it will cool and harden and will become Igneous.
3. Which process changes metamorphic rock into sedimentary rock?
Metamorphic rocks change into sedimentary rocks through the process of weathering. The metamorphic rock will weather, then come to a place where it will layer down and sedimentary.
9. Metamorphism involves the addition of heat and pressure to pre-existing rocks.
10. The compaction & cementation of sediments form sedimentary rocks.
