Granite is formed by what processes.
A) Heat and Pressure
B) Melting (molten magma) and Cooling
C) Weathering, Erosion, Deposition, Compaction, and Cementation
B) What is Melting (molten magma) and cooling
Granite is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground.
