Question

the rock above most likely formed due to heat and pressure hardening of magma or lava minerals precipitating out of solution compaction or cementation

Explanation:

Rocks can form in different ways. Heat and pressure form metamorphic rocks. Hardening of magma or lava forms igneous rocks. Minerals precipitating out of solution and compaction/cementation form sedimentary rocks. Without more details about the rock's texture, mineral - composition etc., it's difficult to be certain, but if it's a non - layered rock with visible crystals, it could be igneous (formed from hardening of magma or lava).

Answer:

hardening of magma or lava
