Answer:
1. Which process changes igneous rock into metamorphic rock?
<u>The temperature, pressure, or fluid environment change, and the igneous rock changes its form and becomes metamorphic.</u>
2. Which process changes sedimentary rock into igneous rock?
<u>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.</u>
3. Which process changes metamorphic rock into sedimentary rock?
<u>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.</u>
9. Metamorphism involves the addition of <u>heat</u> and <u>pressure</u> to pre-existing rocks.
10. The compaction & cementation of sediments form <u>sedimentary</u> rocks.
