Worked example
Which process turns magma into solid igneous rock?
Answer & why
Answer: cooling and solidifying
Molten material becomes igneous rock as it cools and solidifies.

Question 1
Which process can transform solid shale into a metamorphic rock while it stays solid?
- melting
- cooling and solidifying
- compaction and cementation
- heat and pressure without melting
A hint
The rock cycle has many possible paths, not a single required sequence.
Answer & why
Answer: heat and pressure without melting
Metamorphism changes rock in the solid state.
Question 2
Which processes bind loose sand into sandstone?
- heat and pressure without melting
- compaction and cementation
- melting
- cooling and solidifying
A hint
The rock cycle has many possible paths, not a single required sequence.
Answer & why
Answer: compaction and cementation
Pressure packs grains, and mineral cement binds them.
Question 3
Buried rock stays solid but recrystallizes under increased temperature and pressure. Which process is described?
- heat and pressure without melting
- cooling and solidifying
- melting
- compaction and cementation
A hint
The rock cycle has many possible paths, not a single required sequence.
Answer & why
Answer: heat and pressure without melting
This describes metamorphism rather than complete melting.
Question 4
A lava flow becomes a new rock layer after losing thermal energy. Which process is responsible?
- melting
- heat and pressure without melting
- compaction and cementation
- cooling and solidifying
A hint
The rock cycle has many possible paths, not a single required sequence.
Answer & why
Answer: cooling and solidifying
The lava cools from a liquid to solid igneous rock.
Question 5
Which process turns magma into solid igneous rock?
- melting
- compaction and cementation
- heat and pressure without melting
- cooling and solidifying
A hint
The rock cycle has many possible paths, not a single required sequence.
Answer & why
Answer: cooling and solidifying
Molten material becomes igneous rock as it cools and solidifies.
Question 6
Which process turns solid rock into magma?
- cooling and solidifying
- compaction and cementation
- melting
- heat and pressure without melting
A hint
The rock cycle has many possible paths, not a single required sequence.
Answer & why
Answer: melting
Melting changes solid rock material into molten rock.
